Welding is a process of joining two or more parts together through the application of high heat that causes fusion through the cooling of melting surfaces. Electrical resistance welding in particular is a process in which an electric arc and pressure are used for the joining of elements. With the use of a powerful arc, metal pieces may be melted down and forged together through fusion. First invented in the 19th century, electric resistance welding still remains a popular procedure for many applications due to its various advantages over other welding types.

For a majority of modern aircraft, flight is made possible through the continuous combustion of fuel-and-air mixtures that drive turbines, create propulsion, and more. While the power needed for flight is created through such methods, the resulting exhaust from ignited fuel-and-air mixtures needs to be efficiently expelled from the system to avoid major pressure and heat build-up. Exhaust can also be harnessed for increased propulsion in some aircraft after being used to drive systems, making the engine exhaust system a very crucial aspect of any aircraft. In this blog, we will provide a brief overview of common engine exhaust systems and their designs, allowing you to better understand the role they play in powered flight.

The flight line of an airport or airfield is the area near hangars where aircraft may be unloaded, offloaded, and serviced. As a high-level activity space that may have running aircraft, operating APUs, fuel trucks, baggage handling equipment, and other objects present, maintenance technicians and workers must be on constant alert and aware of their surroundings for the means of safety. In this blog, we will provide an overview of the common hazards associated with flight lines, allowing you to understand best practices to keep yourself and others safe.

The induction system is crucial for the operation of a reciprocating aircraft engine, ensuring that air is brought into the system for the means of combustion. As air is brought in from the outside, it is mixed with fuel before being delivered to the engine cylinder assembly for ignition. Due to the relation of the induction system’s ability to draw in air and the general performance of the aircraft, it is important that such assemblies are well-designed and maintained. In this blog, we will discuss how the induction system works and how it supplies the engine with sufficient airflow.

Welding is a process in which two or more parts may be joined together through the use of high heat, pressure, or a combination of the two. While a significant portion of an aircraft may be conjoined with fasteners, many assemblies are also made possible through the use of welding. Depending upon the parts being fused and the materials present, a number of welding processes may be carried out to produce a rigorous and reliable fusion. In this blog, we will discuss some of the primary welding methods used by aircraft manufacturers for the production of components and structures.

The radial engine is a type of reciprocating internal combustion engine in which the cylinders radiate outward from a central crankcase like the spokes of a wheel. When viewed from the front, radial engines resemble a star. For this reason, they are sometimes called star engines. The radial configuration was commonly used for aircraft engines prior to the rise of gas turbine engines. In this blog, we will discuss the operation of radial engines in detail.

The most common type of air conditioning system found in aircraft is the aircraft vapor cycle system. Within this system, there are six major components: the refrigerant, receiver dryer, expansion valve, evaporator, compressor, and condenser. In this blog, we will discuss each component and its role within the system as a whole.

Though it is not necessary for flight, the aircraft electrical system remains one of the most important onboard systems. Exactly how critical electricity is for the aircraft depends on the aircraft design. Some airplanes do not have electricity at all, while in commercial aircraft, electricity is used for safety equipment, cockpit instruments, environmental systems, entertainment functions, and more.

Motor controllers and drives are electrical devices used to regulate motor speed, torque, and position outputs. The drive alters the power input to the motor to realize a desired output. Controller circuits are frequently consolidated with the drive circuits to form a single stand-alone unit, and as such, the terms motor drive and motor controller are frequently used interchangeably. The four basic motor controller and drive types are AC, DC, servo, and stepper. Each type has its own input power type adjusted to the desired output function to match with its intended application.

The aircraft fuel system is crucial to flight operations, providing the engines with a stable flow of fuel from the fuel tanks. As aircraft are constantly in changing environments with extreme conditions, the fuel system must ensure that there is always enough fuel to accommodate for any altitude, attitude, and more. For smaller aircraft, fuel systems often come in one of two types, those being the gravity-feed and fuel-pump system.
