Screws are a type of threaded fastener used to join objects and hold them together. A screw consists of a head and threaded section which, depending on the design, may or may not flush out with the surface during fastening. There are many different types of screw heads including flat head, round head, raised head, truss head, bugle head, and more, each designed and used for a specific purpose. This blog will cover the many types of screw heads and their unique characteristics.

In their most basic form, screws are divided into two groups: countersunk screw heads and non-countersunk screw heads. In a countersunk screw head, there is an angular shape beneath the beneath the head, while in non-countersunk screw heads, there is a flat shape. To create the countersunk head, a countersink bit is drilled into the screw to provide the correct head angle. In non-countersunk screw heads, there is no pre-drilled hole necessary. In each group, there are many further classifications. Countersunk screw heads include flat heads, oval heads, and bugle heads, while examples of non-countersunk screw heads are pan heads, button heads, round heads, binding heads, flange heads, and socket heads.

Countersunk Screw Heads

The first type of countersunk screw head, the flat head, sits entirely in the same plane of the mating surface. These screw heads feature a flat top surface and a cone under the bearing surface with a standard of 82 degrees. These are ideal for use in areas where protrusion is unacceptable, such as in a bookshelf. Other applications of flat head screws include steel applications and door hinges. Oval heads are the same as flat heads but feature a dome-shaped head rather than a flat top, making them slightly more aesthetically pleasing without affecting performance. Finally, bugle heads have a flat top surface and a concave curve shape below the bearing to reduce surface damage. These heads are capable of distributing bearing stress over a wider area and are most commonly used in drywall.

Non-countersunk Screw Heads

Pan heads are the first type of non-countersunk screw heads. These feature a flat or slightly round head with chamfered edges and a flat load-bearing surface on the underside. Pan heads have moderate head height and diameter and provide high tightening torques. Button heads are domed, large diameter heads with high resistance to slipping and stripping. These are ideal for lighter fastening operations and will not be suitable for high strength applications. Round screw heads have a high profile and deep drive cut, but a smaller diameter. These were once the most popular types of screw heads but many now consider them outdated.

Binding heads are similar to pan heads, but feature a much thicker bearing surface and deeper slot, both of which increase the screw’s bearing capacity. A flange head can be considered a combination of a screw and washer. The head can be circular or hexagonal with a washer underneath the load bearing surface. This distributes pressure to help keep the screw in position and increase its bearing capacity. Finally, socket heads are the strongest type of screw head. Known for their quality and reliability, they are made from high grade carbon and stainless steel. Screw heads of this type feature a cylindrical head and long vertical sides. Their head height and shank diameters are equal, allowing them to be used in very high-strength endurance applications.

While computer hardware was often expensive and fairly unobtainable for the standard consumer during the technology’s infancy, prices have since seen a steady drop leading into the present. Now, consumers have much easier access and ability to create more complex and powerful systems with common components available on the market. With a number of consumer motherboards now offering more than one slot for CPU attachment, shared-memory processors can be used to achieve higher system performance for a number of applications.

Shared-memory processors are a type of system that contains multiple processors that may carry out their operations together. Through a shared interconnection network, the processors can utilize the same pool of memory and communicate with one another to carry out various procedures. As such, computers with shared-memory processors can exhibit a significant difference in their computation power as compared to standard work stations with only one processor. As these assemblies are typically geared more towards demanding applications and processes that may require large amounts of program execution, many casual users may not find much use in running a shared-memory processor set-up.

In the case of an internet, database, or network server, however, having the most processors possible is paramount to smooth operations and ensuring that the servers are able to accommodate periods of high usage and user loads. Additionally, shared-memory processors can also serve to streamline certain applications, as a computer system can utilize large amounts of power to conduct a single job rather than computing a high number of small jobs at the same time. When connecting processors together, each processor is joined from their independent data caches to a shared memory pool through a single interconnection network.

Known as symmetric multiprocessing hardware, such components allow for the assembly and pairing of multiple processors so that each CPU has equal control over memory and peripherals. Across most symmetric multiprocessing hardware assemblies, buses and crossbars serve as the primary method for interconnection. In regard to computer hardware, a bus is a component that allows for data to be transferred, and they are commonly seen on many motherboards for the connection of memory, CPUs, and more. A crossbar, on the other hand, is a component containing a series of switches that may be used to conduct information processing applications. Out of the two symmetric multiprocessing hardware pieces, the bus serves as the most convenient and common approach for establishing a shared-memory multiprocessor assembly. With the bus, connections for parts, protocols, and hardware are all provided to facilitate operations with ease. As buses are limited in their ability to handle high amounts of data traffic, it is important that loads do not exceed the performance standards of the bus as to avoid bottlenecking.

With the use of a crossbar, bottlenecking is avoided as multiple paths may operate simultaneously on a grid-like system. As an example, a 4x5 crossbar could allow for up to four active data transfers to be conducted at the same time. By having a higher number of active paths as compared to a singular shared bus, more performance can be achieved. While these advantages are clearly desirable, crossbar components typically range much higher in price, and their cost only increases as the load raises. Due to this, crossbars are mostly reserved for the most high-end applications.

A chip detector is an electronic instrument that attracts ferromagnetic particles such as iron chips. Chip detectors are frequently used in aircraft engine oil chip detection systems, where they can offer an early warning of imminent engine failure, thus greatly reducing the cost of an engine overhaul. This blog will provide an overview of chip detectors and their functions.

Chip detectors consist of small plugs that can be installed in an engine oil filter, oil sump, or aircraft drivetrain gearbox. Over time, engine wear and tear causes small metal chips to break loose from engine parts which then circulate in the engine oil, causing damage. A detector contains magnets incorporated into an electric circuit. Magnetic forces attract ferrous particles and collection of these particles continues until the insulated air gap between the magnets (in a two magnet configuration) or between the magnet and housing (in a single magnet configuration) is bridged, thereby cutting off the circuit. The result of this is an electronic signal for remote indication which activates a warning light on the instrument panel, indicating the presence of metal chips in the oil.

In applications with a self-closing valve/adapter, chip detectors can be positioned in the application through a bayonet or threaded interface. When the chip detector disengages from the valve, the valve closes, keeping any fluid loss from the system to a minimum.The chip detectors used on aircraft are inspected in every level of check. Inspection may also be done at specified intervals such as every 30 to 40 hours for an engine unit and 100 hours for an auxiliary power unit.

            There are many advantages to using a chip detector. For one, no additional tools are needed to inspect and remove debris. Additionally, chip detectors enable BIT capability by integrating a resistor at the chip gap. Chip detectors utilize blade-type retention, which eliminates much of the wear associated with common ‘pin-in-slot’ type retention methods. Furthermore, strong magnet integrity provides high ferrous capture efficiency as well as significant retention.

To further increase capture efficiency, chip detectors are equipped with flow directional screens. In order to support resistor-based wire-fault, built-in-test functionality, chip detectors feature a circuit board integrated with the chip detector. Finally, chip detectors feature an electroless nickel plating for superior wear and corrosion protection, as well as an axial design which improves the detector’s capture efficiency and ease of chip removal.

To save weight, the chip detector assembly is primarily made from aluminum. There are five main parts of a chip detector’s construction: the flying lead, chip gap, ECD-to-valve- retention lugs, seals, and springs. The flying lead construction features three insulated conductors with an overbraid shield. The chip gap is the area where debris is held. An axial chip gap design is able to collect more debris than a radial type. Retention lugs are designed to FAA approval and are integrated in the valve body where they eliminate assembly errors and provide increased bearing area. The seals, usually o-rings, are used to seal the circuits and connections from oil. Lastly, the chip detector features stainless steel valve piston springs to assist in installation and operation.

Within a fluid system, a ball valve serves as a form of quarter turn shut-off valve that may be used to manage the flow of liquids. With a rotary ball that has a straight bore cut through it, fluids can easily pass through the bore while it is positioned along the direction of flow. Once turned 90 degrees, the passage of fluid is removed, blocking liquids from continuing through the system. With this simple operation, ball valves serve as useful components for a great number of residential and commercial fluid applications.

In general, all types of ball valves consist of five main components which are the valve stem, o-ring, valve housing, rotary ball, and valve seat. The valve stem of the ball valve is the rotary shaft that attaches the lever to the ball, allowing for the user to adjust and control flow as necessary. With an o-ring, the stem and housing of the valve can be sealed, ensuring that no fluids escape the system to prevent leakages. To construct the o-ring, various soft materials such as nitrile rubber or plastic may be used.

 The valve housing of the ball valve is what protects the internal components, as well as serves the point in which the valve may be connected to other parts. Metals such as brass and stainless steel are the most common for the construction of the housing, though PVC is also often used. Depending on the application, the housing construction can be one-, two-, or three-piece. The one-piece ball valve is the most cost efficient type, and welding is used to conjoin the valve. As such, they cannot be taken apart for any maintenance and are typically reserved for applications with low demands. Within two-piece style ball valves, parts are connected through threading. As such, these types of ball valve components may be taken apart for conducting maintenance, and the valve can be disconnected from the pipe for disassembly. Three-piece ball valves are those that are clamped together with a bolt connection, and they may not have to be entirely removed for maintenance. While remaining the highest in cost, three-piece ball valve types are the greatest for sanitary needs.

As the rotary ball provides the primary operation of the valve itself, the design of the ball is the most important. Floating ball designs are those that have valve seats that support the ball, and they can serve a diverse set of temperature applications. With a reduced bore type, the flow of liquid is reduced, and thus friction loss is caused. Despite this, the amount of loss is less than other valves and reduced bore design serves as the most common type. Trunnion ball types have support provided to the ball from the top and bottom, thus minimizing the amount of load that the valve seats are subjected to. As such, trunnion ball valve components are useful for high and low pressure applications. The full bore valve design implements a bore size that is equal to the pipe diameter, and this allows for easier maintenance and less friction. Lastly, the V-shaped bore is a design that has a V-shape profile, and this permits precise flow rates that can be optimized for linear flow.

With their simplistic design, reliability, and optimal sealing capabilities, the various types of ball valve components remain beneficial for a number of water and gas applications. No matter your operational needs, the experts at Aerospace Unlimited can help you secure everything you are searching for with ease. As a premier supplier of components for the aviation, defense, marine, medical, electronic, and IT hardware industries, we provide customers rapid lead-times and competitive pricing on all that we carry for their benefit.

Ice can quickly accumulate, as you can usually tell just by looking or using your car on a very cold day. In cold climates, the ice can stick to your windows, blocking your windows. Not only that, but they can also make certain mechanisms stuck (such as a door or a gear) and result in your car not functioning at all, leaving you stranded where you are. These same issues can also affect an aircraft. As an aircraft needs to be functioning at full capacity in order to safely transport its passengers across the skies, the need to apply an anti-icing solution is even more detrimental. The process of using an anti-icing system is somewhat akin to someone applying a deicing solution to the windows of a vehicle before driving. In principle or idea, they are the same, but as you go through the process, you start to notice the differences. In this article, we will break down the process of using an anti-icing system, and also discuss why using these tools is so important.

Plane deicing is a strategy that consists of warming and applying deicing fluid onto the plane windows and wings. The significance of doing this is pivotal because this method ensures the eventual melting of snow that has been cemented onto the plane and, if not removed, could bargain the security of its next flight. The basic idea behind an anti-icing system is to tackle the cause that is making the outer atmosphere conditions to result in ice that can damage your vessel. You can take steps to prevent this by simply hangaring your plane. Hangaring the plane can shield it from ice and precipitation. Before leaving the plane in the safe space, you would need to ensure that there are no traces of water left on its surface, as these surfaces could be at risk of accumulating ice even inside the capacity. That is why it is ideal to clear any traces of water before you store the plane. Various habits by which you can shield ice from forming is by putting wing canvases or covers onto the plane. While it may not be 100% secure against ice, this procedure, notwithstanding the hangaring and water ejection philosophy, can spare time and costs.

There are also some parts and components of the aviation anti icing process and equipment that are important to have for deicing a plane. These constitute stream control valve, deicing boots, heat spread, and pitot tube. The stream valve is significant because it  utilizes a solenoid valve that engages air from the direct to stream into the gadget system. The valve opens once the device is enabled by the de-icing switch. This enables the contraption to work and warm the ice off from the vessel’s edges. Other tools that you can use include deicing boots. They are stretchy rubbery parts that are placed onto the corners of the fuselage, vertical stabilizer and the wing. They work by breaking down any ice accumulating at any point on the plane. Deicing boots are bulky pieces of rubber that are fastened onto the leading edges of an aircraft, typically the vertical stabilizer and the wing. They work by inflating any time there is an accumulation of ice buildup.

Once they’re inflated, snow or ice begin to crack on the surface. Eventually it flies off entirely, leaving no residue of snow. A heat blanket can also be used to cover the surface of an aircraft. The blanket works by trapping heat onto the surface and thus preventing any snow or ice from accumulating. Lastly, the pitot tube is significant because the freezing of these tubes can cause your airspeed indicator to fail. The airspeed indicator receives data on ram pressure but if the pitot tube is frozen over, that can alter the numbers. You may be flying slower than the airspeed indicator perceives. In this case, it is the pilot’s responsibility to descend to altitudes that are free of icing conditions and land, after which aircraft personnel can focus on deicing the pitot tube.

Not only do we provide anti-icing systems in airplanes, but we also stock pneumatic systems and systems for wing leading edge. Get in touch with us today!

Rivet nuts are a type of internally threaded fastener that is often used for materials that are brittle or thin, allowing for fastening solutions for components that are intolerable of hole tapping. The rivet nut features a one-piece design, allowing for it to be anchored from one side of the component. Rivet nuts were originally developed in 1936 for attaching rubber deicing boots to the leading edge of an aircraft wing, and they have since expanded their use to many more applications. In this blog, we will discuss the various types of rivet nuts and rivet materials that may be chosen from, enabling you to find which is best suited for your needs.

Also known as blind rivet nuts, such fasteners may either feature an open end or a closed end. With a closed end nut, the back end of the fastener is completely sealed out, preventing debris and contaminants from entering. To further protection, sealants may also be implemented to deter moisture and lubricants. When choosing which types of rivet nuts are best suited for your application, it is important to consider the torque value, grip range, rivet material, body style, parent material, environment, strength of the rivet, and size of the rivet.

Aluminum rivet nuts are a type that provides the means for facilitating simple connections and provides clean internal threads once installed. They are fairly easy to establish within components and often do not need finishing as well. In general, aluminum rivet materials have benefits such as resistance to corrosion, decreased weight, and high electrical and thermal conductivity.

Where there is a need for a fastener that provides high strength capability and resistance to corrosion, rivet materials such as stainless steel is very beneficial. Stainless steel is very durable, and its resistance extends to corrosion, fire, and heat. It also provides optimal strength to weight ratios, allowing for powerful fastening solutions without greatly increasing overall weight.

Brass rivet nuts are often reserved for implementation in applications where there is a need for a very versatile metal. For sheet metal, brass rivet nuts may be installed very quickly and provide an effective fastening solution, and they are favorable for a wide range of applications. In regards to their capabilities, brass rivet nuts feature good malleability and resistance to corrosion, as well as exceptional tolerance to temperature.

To install rivet nuts, a compression process is used to attach the fastener to the component. This is typically carried out with the use of a special rivet nut tool which squeezes the nut with in-line forces. Depending on whether the rivet nut body is smooth, swage, hex, or ribbed, various torque values may be utilized to ensure a proper installation that will be strong and effective. As various rivet nut types and materials each provide their own benefits, it is important to consider all aspects of the application so that you may find the perfect fit.

Over the course of a product’s life cycle, the device may require certain changes. Before these changes can be made, a manufacturer must acquire a PMA (Premarket Approval) supplement. A PMA supplement is the submission required for a change regarding the safety or effectiveness of a device for which an applicant already has an existing PMA. Similar to PMA supplements, PMA amendments include all additional submissions to a PMA or PMA supplement prior to approval of the PMA, PMA Supplement, or all additional correspondence after the PMA or PMA supplement.

The type of PMA submission depends on a number of factors, the most common of which is the data needed to demonstrate the safety and effectiveness of changes. Despite this, there are many different changes that require a PMA supplement as well as a number of types of PMA supplements. This blog will explain the changes that trigger the need for a PMA supplement, as well as a few of the many types of PMA supplements.

After the FDA has approved a PMA, the applicant must submit an PMA supplement for review and approval before making the proposed changes. Changes for which an applicant must submit a PMA supplement are vast, including but not limited to:

  • New indication for use of the device.
  • Labeling changes.
  • The use of a different facility for the manufacturing, processing, or packaging of the device.
  • Changes in manufacturing methods or quality control procedures.
  • Changes in sterilization procedures.
  • Changes in packaging.
  • Changes in performance or design specifications, circuits, components, principles of operation, or physical layout of the device.
  • An extension of the expiration date of the device based on data obtained under new or revised testing protocols that have not been approved by the FDA. If the protocol has been previously approved by the FDA, a supplement is not needed but the change must still be reported to the FDA.

While there are many types of PMA supplements, the four most common are the PMA Panel-Track Supplement, PMA Supplement (180 Days), Real Time Supplements, and Special PMA Supplements. Panel-Track Supplements are specific to changes that request a significant change in design, performance, or usage of the device. To gain a panel-track supplement, substantial clinical data of assurance of safety and effectiveness is required. 180-day PMA supplements are required for changes relating to the safety and effectiveness of a device, as well as changes in the components, materials, design characteristics, specification, software, or labeling.

Real time supplements are needed when a minor change to a device, such as a change in its design, is requested and the FDA has granted a meeting or similar exchange to review the status of the supplement in real time. Special PMA supplements are required when any changes enhance the safety of a device or the safety in use of the device, or for certain labeling and manufacturing changes that enhance the safety of the device. Special PMA supplements can be placed into effect by the applicant prior to the receipt of a written FDA order approving the PMA supplement.

PMA supplements are critical in any highly-regulated industry. At Aerospace Unlimited, owned and operated by ASAP Semiconductor, we can help you source all types of FAA PMA supplements parts through our PMA supplement list and deliver them with some of the industry’s best lead times.

As we continue to move through these unprecedented times during the COVID-19 pandemic, more United States manufacturers are stepping up to aid in the supply shortage of ventilators and masks that are desperately needed by medical professionals and other affected sectors. Leading into June, car manufacturer Ford has joined companies such as 3M and General Electric to aid the medical community in this initiative.

Currently, Ford is not the only carmaker to contribute to the pandemic efforts, as similar decisions have also recently been made by companies such as Tesla and General Motors. Medical equipment such as medical masks and ventilators are a crucial need to treat an increasing number of symptomatic carriers, and shortages have proven to be a major issue currently. With the help of Ford, 3M’s output of powered air-purifying respirator (PAPR) masks is to be expanded. With an increase in production, state governments and other sectors may see more supply of needed medical equipment.

Together with 3M, Ford hopes to increase the manufacturing and supply of PAPR masks as quickly as possible, and they seek to utilize established technologies and products from their respective companies to aid in the effort. Ford also claims to be working alongside the health care division of GE in order to create a more simplistic ventilator. Without furthering information, Ford claimed that ventilators could be produced at both Ford and GE locations concurrently. As droplets from a person’s coughing or sneezing may lead to infection with the novel coronavirus, Ford also seeks to begin testing and production of new face shields that may further protect the medical professionals who are in close proximity with affected patients and individuals.

Other car manufacturers, such as General Motors and Tesla, have also been making strides in the production and supply effort with their respective initiatives. Recently, GM announced that they are partnering with Ventec Life Systems, a manufacturer of ventilators, to increase their logistics, manufacturing, and issues to improve output. Tesla has also been aiding in supply, providing ventilators to the state of California in March. For the University of Washington’s Medical Center, Tesla sent around 50,000 3M produced N95 surgical masks.

While companies such as Ford, General Motors, and Tesla have recently joined the fight against the pandemic, they are not alone in their efforts. Through the past months and moving into the future, we are seeing a great increase in United States companies working to fortify the strained medical infrastructure and medical care system. From boosting the supply chain for sourcing supplies and hastening production of highly needed medical materials, many American companies are spearheading manufacturing initiatives to combat COVID-19. As we continue to protect people and various sectors from the devastating effect of the virus, we may see even more companies step in to provide support.

Within a plumbing or fluid system, valves are important components that are implemented to regulate, control, and direct the flow of fluids within the system. Solenoid valves are a special type of valve that is operated electromechanically, and they may perform many of the same functions of a standard valve automatically. With various types available that offer diverse sets of capabilities, solenoid operated valves may benefit a number of plants, equipment, and applications. In this blog, we will discuss the functionality of solenoid valves, as well as the applications that they benefit.

Unlike standard valves, solenoid valves do not need to be operated manually, and thus they open up the capability of remote control to serve as externally piloted valves. The main components that form the solenoid valve assembly are the subassembly, core tube, bonnet, hanger spring, backup washer, diaphragm, disk, and valve body. Within the solenoid subassembly, there is typically a retaining clip, solenoid coil, core tube, plugnut, shading coil, core spring, and core. Altogether, these parts provide for the automatic control of fluids within the system.

Solenoid valves operate by opening and closing orifices within the body of the valve, either permitting or denying the flow of fluids. The opening and closing of these orifices is done by the plunger within the sleeve tube that is actuated by a magnetic field. Such magnetic fields may be produced by having a current run through the coil of the solenoid, energizing it to create the magnetic field. This magnetic field and energizing of the solenoid is harnessed to convert electrical energy into mechanical energy for valve operations. The seals of a solenoid valve may be metallic or rubber, and electrical interfaces may be present to create an ease of control.

The main benefit of a solenoid valve is the ability to remotely control functions, as well as permit more complex processes within a system. Solenoid valves create the ability to easily shut off, release, dose, distribute, and mix fluids within a system. On top of their capabilities, solenoid valves also tout high reliability and service lives, as well as permit fast switching, low control power, and are compact in design.

Within industries and applications, the use of solenoid valves may range from simple on and off control of dishwashers to plant control loops. Common uses of solenoid valves include applications such as water supply, fuel supply, wastewater treatment, oil and gas burner control, blood analysis instruments, gas mixture regulation, pressure relief and drainage, large heating systems, machine engineering, and much more. Depending on the application, various solenoid materials may be used, such as brass, stainless steel, aluminum, and plastics. Solenoid valves may also be direct current or alternating current powered, as well as may be one or two solenoid valves. Since their debut in the 1910, solenoid valves have been greatly beneficial to a number of hydraulic and pneumatic systems.

When it comes time to begin sourcing the solenoid operated valves and aerospace components that you need for your next project or operation, Aerospace Unlimited has you covered with everything you are searching for. Aerospace Unlimited is owned and operated by ASAP Semiconductor, and we can help you find the aircraft and marine parts that you are searching for, new or obsolete.

Aircraft ground support equipment (GSE) refers to the equipment and components that are used to provide servicing and operations for aircraft in-between flights while they are grounded. GSE components and equipment may be used for aircraft mobility, loading operations, ground power operations, and other operations as needed. As commercial aircraft and airliners adhere to strict flight schedules, the efficiency and speed of aircraft ground support services is always a facet that providers strive to improve in order to minimize turnaround times. Over the forecast period of 2019 to 2025, the market for aircraft ground support equipment is expected to increase by $2.2 billion, equaling a compound annual growth rate (CAGR) of 4.45%. Altogether, this forecast puts the total market value at $9.7 billion by 2025. From technological advancements of GSE equipment to steadily increasing passenger air traffic, many factors contribute to this upwards growth. In this blog, we will discuss how ground support equipment aids in aircraft servicing, as well as the factors contributing to the market growth for the 2019-2025 forecast period.

In general, aircraft ground support equipment and services are not only tied to maintaining the aircraft’s ability to fly, but also encompass many other services and operations. In-between flights, GSE operations ensure that passenger comfort and safety is established and well maintained. This includes cleaning passenger cabins to remove trash and waste, as well as the restocking of consumables. GSE services also include cycling items such as blankets, pillows, magazines, tissues, and soap to maintain cleanliness for passengers. During this time, security of the aircraft can be established as personnel check for any concerning paraphernalia left behind after a flight. During their normal routines, GSE services will also remove waste from lavatories, cater food and drinks, and even provide electricity and air conditioning for terminal gates for crew and passenger comfort.

Nevertheless, aircraft ground support equipment will also be used for many normal in-between flight tasks. During this time, GSE personnel aid with the loading and unloading of cargo and passengers, refuel the aircraft, examine engines and the fuselage, and perform other ground operations to ensure safety and optimal operation of the aircraft before its next scheduled flight. Often, all of these ground services will be fulfilled by a subcontracted airport or handling agent. With smaller airlines, larger carriers may be subtracted, or they may establish a Maintenance and Ground Support Agreement with another airliner. To perform their operations, ground services utilize GSE components such as dollies, chocks, tripod jacks, service stairs, refuels, tugs, tractors, ground power units, buses, container loaders, and other vehicles and equipment.

Due to their benefits and services for aircraft preparation and operation, combined with an increased amount of air traffic, demand for GSE components and equipment is on the rise. Electric ground support equipment has been seeing increased amounts of interest, especially with the advent of more automated equipment options. Automation with robotic technology is slowly being introduced, allowing for streamlined operations such as automatic shut downs, ID cards for authorization, and electronic check-ins such as seat belt requirements before equipment can be turned on.

Within the realm of aviation, landing gear proves to be one of the most important systems of the entire aircraft. Through the many aircraft landing gear components working together, an aircraft is able to touch ground and come to a stop safely and efficiently, avoiding damages. This is due to their specifically engineered designs that are in place to meet various requirements of weight, size, performance, and beyond as per FAA regulations. In this blog, we will discuss the aircraft landing gear system and how it helps bring an aircraft safely to a stop after flight.

Aircraft landing gear components work together to aid the aircraft during taxiing, landing, and take-off operations. Due to various needs and requirements surrounding these operations, landing gear is more often than not the first consideration and designed component of an aircraft. Designing and manufacturing landing gear can be a lengthy process due to having to uphold various required airworthiness regulations and to best serve the aircraft they are intended for. Depending on the type of aircraft and its application, different designs and equipment may be utilized as well.

To achieve a successful landing, each of the aircraft landing gear components have their own functionality and purpose. Piston landing gear, such as airplane wheels, are often fitted with shock absorbers to take the impact forces of landing off of the fuselage, and wheels also allow for taxiing around a runway. Disc brake and other brake types on the wheels have the important function of slowing down the aircraft speed until it can safely stop or taxi. Airplane wheels may also be installed in various numbers and arrangements, the most common being the taildragger and tricycle undercarriage. Often, landing gear may have the ability to be retractable and can be deployed and/or retracted into the fuselage while in flight with the aid of hydraulic systems. With retractable landing gear, aircraft can reduce drag that would be caused by the wheels and other systems.

Future plans for developing landing gear technologies include using high strength materials, damping systems, and electronic actuation. With high strength materials, fatigue and corrosion can be reduced for longer equipment lifespan. Damping systems are important to reduce fatigue and wear as well, as these electronic systems are slowly proving to be a very viable alternative for the replacement of hydraulic actuation systems. This is due to the fact that electric actuation systems are beginning to compete in weight, and do not have the problem of flammability and leaking that hydraulic systems have. Beyond these examples, there are many other goals of the aviation community to bring improvements to landing gear design and functionality.

PMA stands for Parts Manufacturer Approval. This approval is what allows for manufacturers to produce and sell articles for installation on type certification products. The approval can only be given by the United States Federal Aviation Administration. Simply put, the FAA is required to utilize the PMA process to greenlight the design and manufacturing of certain aviation and aerospace parts. Designing, manufacturing, distributing and operating with such a part that has not gone through the approval process is illegal and subject to severe punishments. For more information on how the PMA process works, you can read more about it in the article below.

You can observe a great example of the PMA process when aviation companies need to acquire replacement parts (such as an aircraft brake) for a commercial or corporate jet. In order to procure these parts, they must ensure that the desired piece passes the PMA phase. This involves the FAA identifying airworthiness standards before applying them to the part and then determining the criticality of this part. The two FAA branches involved in implementing this are the Aircraft Certification Offices (ACO’s) and the Manufacturing Inspection District Offices (MIDO’s). Afterwards, aviation authorities would submit a test plan for its design approval and if passed, establish an inspection system to scrutinize the nooks and crannies of the piece.

If the piece passes this phase of the process, the PMA part would then need established instructions for repair and inspection, followed by instructions for a continued operational safety plan. Once everything has been set in place and tests have been run enough times to prove the airworthiness of the part, only then can the ACO and MIDO give the final approval that the part is suitable enough to fly the skies.

Aircraft wings are airfoils that attach to the body of an aircraft at different angles and shapes to create lift and sustain flight. Different wing configurations provide variant flight characteristics like the amount of lift generated, the level of control at different operating speeds, aircraft stability and flight balance. Aircraft wings may be attached at the bottom, mid or top of the fuselage. The wing tip can be pointed, rounded or square and the wing can extend out from the fuselage perpendicularly , angled down or slightly up. The angle at which a wing extends out from the fuselage’s horizontal state is called the dihedral angle and this affects an aircraft’s lateral stability.

Wings are mostly constructed using aluminum, but they can also be made using wood covered with fabric, magnesium alloy, carbon fiber, and in modern aircraft, stronger and lighter materials like titanium. The framing of aircraft wings are outlined by beam like spars. The ribs of a wing are connected to these spars and provide sound structure and stability. Lastly, the entire aircraft from fuselage to wingspan is covered in a skin that ensures the aircraft moves through the sky as one unified body.

There are 9 types of wing design that each offer their own unique capabilities. The rectangle wing (not aerodynamically efficient) is your basic non-tapered, straight wing, mostly used in small aircraft, extending perpendicular to the fuselage. Elliptical wings (most aerodynamically efficient) induce the lowest possible drag and their thin wing structure was initially designed to house landing gear, ammunition and guns inside the wing. The chord of a tapered wing varies across it’s span for approximate elliptical lift distribution.

Delta wings are triangular in shape and lay over the fuselage. Their low aspect ratio makes them ideal in supersonic, subsonic, and transonic flight. These wings have improved maneuverability and reduced wing loading but due to their low aspect ratio, do have a high induced drag. Trapezoidal wings offer outstanding flight performance, highly efficient supersonic flight, and have great stealth characteristics. Ogive wings are designed for very high speeds, have minimal drag at supersonic speeds, but are very complex and difficult to manufacture. Most high-speed commercial aircraft use a swept-back wing design that reduces drag at transonic speeds. Forward-swept wings have controllability issues and because of the flow characteristics the outboard wings stall before the flaps. Variable sweep wings were designed to optimize flight experience over a range of speeds and have three modes of extension: straight out to the side, slightly back, and farther back to create a triangle shaped aircraft.

Aircraft are defined by their wings. The shape, size, and configuration will affect all aspects of an aircraft’s performance and specifications. Wings are airfoils, shapes designed to create lift when moving rapidly through the air. This lift, combined with the thrust generated by the aircraft’s engine or engines, is what allows an aircraft to fly.

Wings come in various different configurations and shapes, depending on the requirements of the aircraft and its intended use. A wing’s shape will determine how much lift it generates, how the aircraft controls at various operating speeds, stability, balance, and more. Both the trailing edge and leading edge of an aircraft wing can be curved or straight, and wings can attach at various points on the fuselage- bottom, middle, or on the top. There is also the wing dihedral angle, which is the angle at which the wing is set, either perpendicular, or angled up or down.

Aircraft wings are typically built in a complete cantilever design, meaning that they do not require external bracing or support, and are internally supported by structural members and the aircraft’s string. Some designs, however, do feature external wires or struts to prevent vibration and maintain structural integrity. Most wings are built from aluminum, but older aircraft will use wood frames covered in fabric. Modern aircraft often use carbon fiber materials in their construction as well. Wings typically consist of stringers and spars that run spanwise, and formers, bulkheads, and ribs that run chordwise, from leading edge to trailing edge.

Common wing shapes include:

Rectangular:

The rectangular wing is easy to manufacture, and features a non-tapered, straight design used mostly in small aircraft that extends from the fuselage at a 90 degree angle. However, rectangular wings are not very aerodynamically efficient.

Elliptical:

These wings are very aerodynamically efficient and induce minimal drag. However, they are very difficult to manufacture. Elliptical wings were originally designed for military aircraft to house landing gear, guns, and ammunition inside a wing. The ellipse shape was designed to offer the thinnest possible wing, all while holding all these components.

Tapered:

Created as a compromise between elliptical and rectangular designs, tapered wings feature a chord that gradually grows smaller closer to the tip. While not as efficient as elliptical wings, tapered wings offer a compromise between efficiency and manufacturability.

Swept-wing:

Most modern aircraft feature swept-back wings, as they reduce drag and maintain controllability while flying at transonic speeds.

Delta:

Essentially a massive triangle-shaped wing, delta designs are a very low aspect ratio wing used in supersonic aircraft. Delta wings are efficient in all phases of flight, subsonic, transonic, and supersonic, and offers a large surface area which improves maneuverability and reduces wing load. Delta wings are also structurally sound, possess a large volume for fuel storage, and are simple to manufacture and maintain. However, delta wings create lots of drag, and at low speed operations they force a high angle of attack because of vortices creating lift, which makes take-offs and landings challenging.

Variable sweep:

These designs feature wings that are mounted on mechanical hinges that let them alter their profile mid-flight that can sweep the wing back and forth. This lets the wings alter their profiles to be more suitable for low speed or high speed operations. However, these wings are very mechanically complex, and require lots of maintenance.

RC helicopters have been a fairly popular hobby for many for a long time. They allow many to simulate what it is like to fly a real helicopter and can provide much enjoyment. While the complexities of an RC helicopter may be much less than their real counterpart, there are similar components and controls. For the purpose of an RC helicopter, there are five main components which are the main and tail rotors, swashplates, cyclical control, and collective control.

Attached to the fuselage, the main rotor consists of two or more blades and is what enables the lifting power of the RC helicopter. This amount of lift is dependant on the inclination angle of the blades, as well as their velocity. Often, the RPM of the main rotor ranges anywhere from 1500-3000. By increasing the main rotor’s pitch, increased push and lift force can be achieved. The tail rotor is also important as it is what keeps the helicopter from spinning around in circles due to the force of the main rotor. By increasing or decreasing the thrust of the tail rotor, one can then steer the helicopter.

The swashplates are important as they are what translate the flight control input for the main rotor of the RC helicopter. A swashplate consists of two discs, one that is stationary and another that is moving. With cyclical controls, the swashplate can be tilted in any direction, as well as up and down through the use of collective controls.

Cyclical control allows for the helicopter to have 360 degree movement through the tilting of the oscillating plate and separately elevating the rotor pitch. The helicopter will begin to tip towards the direction of the side that has the lowest altitude. Collective control, on the other hand, changes the rotor blade pitch in unison to the same degree. The RC helicopter’s radio transmitter is able to control and translate the cyclic and collective movements.

A helicopter is a type of rotary aircraft in which thrust and lift are achieved through the use of spinning rotors. This allows the aircraft to take off and land vertically and hover at a fixed altitude. Despite helicopters being far smaller than most airplanes, the rapidly-spinning rotors make it very hard to control. Each helicopter is made of five main parts: the cockpit, main rotor, tail rotor, landing gear, and engine. This blog will explain each of the five main parts in further detail.

The cockpit is the brain of the helicopter. It serves as the central control unit and determines all the activity of the helicopter. The pilot and co-pilot reside in the cockpit, however some helicopters do not require two people to control. The four most important control the pilot uses in the cockpit are the cyclic, collective, anti-torque pedals, and throttle.

Just as the cockpit is the brain of a helicopter, the main rotor is the heart. It is perhaps the single most important component of the helicopter. The main rotor allows the pilot to control which way the helicopter turns, changes altitude, and moves laterally. The pilot commands the rotor with the cockpit controls linked to the swash plate assembly. The tail rotor is found at the rear end of a helicopter and is necessary to counteract the torque caused by the main rotor. If the tail rotor were not present, the aircraft would spin in the inverse direction of the main rotor.

Landing gear comes in a variety of types but skids and wheels are the most common. Floats, pontoons, and bear paws are also used. Bear paws are an attachment to skids used when the helicopter is landing off airport on unstable terrain providing more stability. The two types of helicopter engines are reciprocating and turbine. Reciprocating engines use pistons to convert pressure into motion thereby creating power. Turbine engines create power by mixing compressed air with fuel to create high-speed gas to turn the turbine blades.

A rough look at history will show you that it took humanity more than 10,000 years to invent flying machinery. Yet it was only 66 years later in 1969 that humanity accomplished aeronautical aviation and landed a human on the moon. This goes to show that the more we discover and create, the faster it enables our world to grow. You need only look at these recent years to see that technology is advancing at a rapid pace and the next years are sure to unveil amazing advancements in flight. Read on below for some new concepts emerging in the aviation industry.

Electric Aircrafts

Among the most exciting news to come out in aviation is the optimistic potential for aircraft to be powered by electricity. Currently, airplanes are being designed to use exclusively electricity when on the ground. Professionals are working soon to extend this feat into the air. Having electrical aircrafts replace fuel running airplanes could greatly benefit our environmental health by reducing fuel consumption, as well as air and ground pollution. An electric aircraft would also emit little if any noise, meaning communities near airports could potentially see value rise.

Automation

Smart technology and machine learning have made great strides in the last five years and now that self driving cars have been released into the market, it’s very possible that self driving aircraft will become a standard in the coming years. Remote controlled aircraft is currently being used, but tests with self learning machinery have proven that the latter shows less likeliness of collisions.

Improved Aircraft Experience

Part of what has improved aircraft experience is the increased connectivity that there now is between passenger and cabin crew. While the first years of commercial flight saw passengers having to flag down the newest steward or stewardess, these recent years now have cabin crew and passengers connected via touch screen computers. Some experts speculate that the rise of automation may even present opportunities for the pilot crew to connect with the passengers.

Every airport, from the largest international to the smallest regional, needs ground service equipment to support and operate fleets of aircraft flying in and out of it. Ground service equipment needs to be regulated, however, so that crews always know what they are dealing with, no matter where in the world they are. Over four decades, standards for GSE have evolved, culminating in the international standards that are applied worldwide.

The ISO TC20/SC9, air cargo and ground equipment subcommittee was started in the late 1960s to define the standards for the new and developing types of GSE needed to service new wide-body commercial aircraft like the Boeing 747. This task is never truly completed, as there are always new generations of aircraft with new generations of ground service equipment accompanying them. Over the years, the ISO TC20/SC9 has had to respond to containers and aircraft towing, the introduction of regional commercial aircraft, and even the enormous A380 produced by Airbus, the first aircraft with full length double-deck.

Significant market changes have occurred over the years as well. Sub-contracting has led to more and more service providers, while airlines have dropped their own specifications for purchasing equipment and begun to buy off-the-shelf equipment instead. This has forced ISO standards to be applied at the design stage by equipment manufacturers instead. Airborne equipment like unit load devices have needed to be regulated to ensure they comply with civil aviation regulations, while ground service equipment TC20/SC9 standards have had to be expressed in terms of function and performance requirements to leave the wide variety of technical designs open.

Recent TC20/SC9 projects have involved the advances in aircraft de-icing technologies, replacing forty year old criteria used to certify air cargo ULDs with a more streamlined and modernized document, and updating the regulations and standards for baggage handling to improve the health and safety of workers involved. This last example is part of a major trend recently of trying to improve human resources and reducing the overall cost to operators, which are heavily burdened by the cost of work accidents and professional disabilities. Work interruptions, early retirements due to disability, and health insurance costs can be ruinously expensive for both workers and employers, a cost that can be lowered with proper regulations and standards.

Future challenges that the TC20/SC9 program might face include performance standards for passive and active aircraft interface protection systems that shield aircraft from damage from GSE due to collisions, better ground electrical supply requirements, improved function and safety requirements for aircraft bulk loading systems (ABLS), higher standards for safety in dispatch towing, and more.

The NSN system can be dated back to the WWII era when the military would use a specific component that had several different names depending on who supplied or manufactured the component. This made it difficult for the military to locate suppliers, or share items between the different organizational branches. An item could be in short supply in one location, but in surplus in another. To overcome this sourcing issue, the Department of Defense created the NSN system. National Stock Numbers or NSNs, are 13-digit serial numbers assigned to all standardized items within the federal supply chain. All components that are used by the U.S Department of Defense are required to have an NSN, the purpose of which is to provide a standardized naming of components.

Also known as NATO stock numbers, NSNs are recognized by all NATO countries. The NSN can be further broken down into smaller subcategories, each providing individual information about the component. To begin, the first four digits of the NSN are known as the Federal Supply Classification Group. The FSCG determines which of the 645 subclasses an item belongs to. The FSCG is further split into the Federal Supply Group (FSG) and the Federal Supply Classification (FSC). The FSG is made up of the first two digits of the NSN which determines which of the 78 groups an item belongs to. The second 2 digits make up the FSC, which determines the subclass an item belongs to. In the aerospace industry a key federal supply group is FSG 15: Aircraft and Airframe Structural Components. The remaining 9 digits are made up of the 2-digit country identifier followed by the 7 National Item Identification Number (NIIN). The US for example, has the country identifier 00.

A manufacturer can not simply request an NSN. An item must first be formally recognized by one of the following bodies; Military service, NATO country, federal or civil agency, or various contractor support weapon systems. Once they have a specific need for the specific part, the details are then sent over to the DLA for assignment. There are 10s of millions of items with NSNs. They aren’t just assigned to one component either. In fact, entire systems are assigned their own NSN. Aircraft turbine engine have one NSN, while the smaller components of the system have their own. The purpose of this system is to help expedite maintenance and repair programs. To help manage the vast amount of NSNs, each NSN is assigned an item manager, who monitors the stock and supply of the NSN, ensuring that it is readily available military purposes.

Due to the sheer amount of NSNs, the DLA relies on suppliers to source and stock NSNs for various applications. Aerospace Unlimited, owned and operated ASAP Semiconductor, is a premier supplier of NSNs for the aerospace and defense industries. Our large inventory is conveniently listed on our website under various categories such as Federal Supply Groups, CAGE codes, and the manufacturers. Our team of dedicated staff can help find the exact NSN that you need. Visit our website, https://www.aerospaceunlimited.com/, or call us at +1-412-212-0606 to source NSNs today.

Exciting news from Honeywell about the iconic T55 turboshaft engine surfaced in mid-April. A pair of T55 engines powered a Sikorsky-Boeing SB-1 DEFIANT in a Vertical Lift demonstration intending to revolutionize the U.S. Army Aviation branch.

 
This new and improved engine has been in the final stages of development and will be showcasing new technology to increase reliability, availability ,and decrease operational costs. John Russo, senior product director at Honeywell, claims it is a new era for T55 engines. He told reporters at a press release that this new aircraft engine will lower fuel burn while simultaneously increasing aircraft load and flight range. This is exciting for manufacturers and civilians alike.
 
The T55 has already been used in the U.S. Army’s Chinook helicopters for some time now, but this latest advancement will take the Army into a new modernized generation of technology and infrastructure. In addition to all the aforementioned benefits to this engine, there is also a downstream result of greater overall horsepower. The T55 can be incorporated by a kit at overhaul by Honeywell or the Army location in Corpus Christi, Texas or as a new production, forward fit option.
 
Honeywell is in a great position. Testing will continue on the DEFIANT as the U.S. Army weighs their decision on its future Vertical Lift platform. Honeywell will now offer a common, but equally extraordinary, engine for both the Chinook helicopter and the aircraft eventually chosen by the Vertical Lift procurement team.
 
John Russo adds that the T55 engine is now brought up to the latest certification standards to set a long-term growth pattern for power increases, decreased fuel needs, and airframe weight increases. John Russo finishes by saying that he looks forward to powering many more flights in the years to come.
