When it comes to aviation, safety is paramount, and with millions of passengers traveling by air every day, providing a secure and comfortable flight experience is of the utmost importance. One crucial aspect of maintaining an aircraft airworthy and compliant with aviation safety standards is the aircraft engine fire extinguishing system. This system plays a vital role in preventing and extinguishing engine fires, in addition to safeguarding both passengers and crew. For this reason, in today’s blog post, we will explore the key components and considerations of aircraft engine fire extinguishing systems in more detail.

Commuter aircraft certified under 14 CFR part 23 must be equipped with, at minimum, a one-shot fire extinguishing system, whereas all transport category aircraft are required to have a two-shot system. Regardless of the type of system in question, each produces ample agent concentration. An individual one-shot system can be utilized for auxiliary power units (APUs), fuel burning heaters, and other combustion equipment. Meanwhile, for “other” designation fire zones, two-shot systems are used, each of which generates sufficient agent concentration as well.

Spark plugs are installed in vehicle engines in a way so that there is usually one spark plug per cylinder. They are small, conductive devices through which energy flows and creates a spark for ignition purposes, making them useful in airplanes, in addition to other vehicles. Typically constructed of electrically conductive materials like copper, the inner core of a spark plug allows electricity to flow through it, creating a spark on the other end as a result. In short, spark plugs deliver electric current from the ignition system to the combustion chamber of an engine, and this current is used to ignite the fuel mixture in the combustion engine to propel the plane forward.

Modern commercial aircraft often consist of a plethora of parts that come together to create their assemblies; models like the Boeing 747 consist of around six million components alone. Each of these parts will play a specific role that benefits the vehicle as a whole, making even the most minute items important. One such part type is the hose clamp, those of which are used to secure hoses that transport oil, coolant, fuel, and other such fluids. During standard operations, hoses can become pressurized, potentially expanding as a result of heat or other such forces. To ensure the safety of assemblies and the prevention of leaks, it is important that the right types of hose clamps are chosen. As such, we will discuss the main factors that one should consider when making a purchasing decision, ensuring that you make an optimal investment.

Hose clamps function as a fastening device for hoses of various sizes. Whether the application calls for affixation to an engine block or a simple housing, hose clamps can be used to prevent leaking and disconnection. Since these devices can be manufactured to fit the needs of virtually any industry, it is no surprise that hose clamps are among the most popular fasteners on the market. Despite their widespread use, it is easy to make mistakes when purchasing a hose clamp for the first time. Installing the wrong fastening element leads to downtime and higher costs which is why it is critical to choose the correct item from the start. In this blog, we will talk about the several considerations one should have in mind when purchasing a hose clamp for their operations.

Of the many elements on a plane, the control surfaces on an airplane’s tail are one of the most essential components to maintain steady flight. A conventional aircraft tail consists of two flat surfaces oriented at right angles to one another: a horizontal stabilizer and a vertical stabilizer. Together, they are referred to as the “empennage,” a word with French origins that translates to “feather an arrow.” This is a good description of the tail section, as just like a feather on an arrow, the empennage stabilizes the aircraft in flight. However, the tail is not simply there to stabilize the plane, but also to control its pitch and yaw. To accomplish this, the tail has control surfaces called the elevators and the rudder, both of which can be moved up-and-down or left-and-right to adjust airflow across the fuselage. To learn more, read on as we discuss two of the most important components on aircraft.

Modern aircraft are incredibly powerful with their ability to travel great distances across sea and land at incredible speeds thanks to the invention of the jet engine. Initially, the only jet engines available on the market were turbojets; however, today, the most common type of jet engine is the turboprop, that of which is used to power the Boeing 787 to the Airbus A850, some of the most popular commercial jets. These propulsion systems burn both fuel and air by moving larger volumes of air at lower speeds to increase efficiency compared to the turboprop. For your better understanding of the driving force behind most modern air travel, this blog will explore the ins and outs of a turbofan jet engine.

Wingboxes are an integral part of many fixed-wing aircraft, wherein they form the structural center of aircraft wings while simultaneously allowing for the use of other wing parts, such as flaps and wingtips. Serving as the primary load-carrying structure in aircraft, the wingbox runs along the wings and into the fuselage. To better understand these complex devices, this blog will cover five facts about wingboxes you may not be familiar with.

Engines are complex apparatuses equipped with numerous components and assemblies that allow them to work optimally. One feature in particular is called the air entrance, and it is designed to conduct incoming air to the compressor with a minimum energy loss, ensuring that air flow is free of turbulence. To achieve such ends, proper inlet design contributes significantly. It improves aircraft performance by increasing the ratio of compressor discharge pressure to duct inlet pressure.

While many aspects of aircraft are becoming ever increasingly electrical, there are still countless mechanical devices that perform operations paramount to conducting a standard flight operation. For many aircraft, pulleys are a common mechanical device that is able to apply a pulling force through the use of a wheel and cable assembly. With a pulley, connected objects can be pulled and provided tension with ease, allowing for pilots to manage various important assemblies and systems. In this blog, we will discuss the most common aircraft applications that pulleys serve so that you may better understand their importance and uses.

An emergency locator transmitter (ELT) is an independent battery-powered transmitter that is activated by the excessive G-forces exerted during an aircraft crash. They have the ability to transmit a digital signal every 50 seconds on a frequency of 406.025 MHz at 5 watts for a minimum of 24 hours. This signal can be received anywhere in the world by satellites in the COSPAS-SARSAT satellite system.

Engine mounts are probably one of the most important parts in a vehicle or industrial machinery and can be found in airplanes, cars, trains, boats, buses, and any other equipment that necessitates a motor or engine. They are tasked with keeping engines in place, allowing any moving machine to optimally function. For example, when putting fragile components into a box and shaking the box around, the items inside will inevitably become damaged. However, if the components inside are secured with a mount, they will remain intact.
