While years of research and innovation went into making the first aircraft, early designs, and still current designs, are far from perfect. The aviation industry continues to evolve, making constantly better designs. One major shift in aircraft design was the change in the location of the engine. Aircraft once had engines attached to the nose, above the wings, blended into the wings, and the rear fuselage. Today, most aircraft engines are stored under the wings for better overall performance. Many factors contributed to this shift in design, so this blog will explore the reasoning behind the engine’s new location for your better understanding.

Aircraft are highly advanced flying machines, and they feature a wide variety of technology and systems that make them one of the safest ways to travel by far. With large, complex aircraft like Boeing and Airbus wide-body airliners, there are many systems spread across assemblies that are crucial for flight, and having the ability to monitor their health and respond to issues is paramount to avoid any hazards. Generally, pilots and crew members will rely on altering systems such as the EICAS to maintain awareness and safety, and having a general understanding of such systems can be beneficial for anyone involved in the industry or those who hold an interest in aviation.

With the constant demands placed upon general aviation aircraft, it is critical to have a robust ground operations network. With multiple actions needing to be accomplished between flights, owners often look for entities capable of efficiently providing a wide range of services. With the current air transportation model, owners of both private and commercial aircraft have numerous options for ground service operators, but most choose to depend upon a fixed-base operator (FBOs). To provide a better understanding of the role that FBOs play, we will discuss some of the services they offer, as well as the equipment that supports them.

The introduction of the turbojet engine brought about a revolution in the operating capabilities of many aircraft. Producing more power, faster speed, and higher fuel efficiency, turbojet engines became the staple for commercial and military aircraft. The turbojet is equally complex as it is impressive, but anybody with an interest in aviation should take the time to understand the fundamentals of these machines. In this blog, we will discuss the operating principle behind turbojets while also highlighting the various forms that may be found in standard aircraft.

Whether you are flying a simplistic trainer aircraft or a robust military fighter jet, most modern aircraft rely on the combustion of fuel and air to create the power necessary for flight. Fuel combustion takes place in the engine of the aircraft, making it an essential element for aviation. While there are a diverse set of engines that exist for varying types of planes, most share a standard set of components that work together to make fuel combustion possible. In this blog, we will provide a brief overview of the most common engine components that are found in the aircraft engine.

Propellers are aerodynamic devices that change rotary motion from an airplane engine or other related power source into propulsive force, allowing the aircraft to traverse the sky with ease. They can be fastened directly on a crankshaft of a piston engine or powered through a reduction gear box (RGB) attached to a piston or jet engine. The RGB converts the high rotation speed of the engine into the appropriate speed for propeller operation.

One of the leading reasons aircraft incidents occur in cold weather is due to aircraft icing. Aircraft icing is defined as the coating or deposition of ice on any part of the aircraft, caused by the freezing of liquid hydrometers. Such occurrences make it hard for pilots to efficiently and safely navigate aircraft.

In order to carry out safe and efficient flight operations, it is crucial that pilots have the ability to properly track the amount of fuel that is on board. While a vehicle such as an automobile could simply pull off a road and stop in the case that it runs out of fuel, such safe stops are not possible for aircraft due to their airborne operation and average speeds. As aircraft may vary in the amount of fuel tanks they have, the placement of their tanks, and the general design of the fuel system, fuel quantity measurement must be accurate and accommodate for the construction of the aircraft. In this blog, we will discuss fuel quantity indication systems, allowing you to better understand how they are designed and how they function.

Auxiliary power units (APUs) are specialized devices installed in vehicles to provide energy for various functions. Found in large aircraft, naval ships, and large land vehicles, APUs allow them to operate autonomously without the need for GSE such as ground power units, external air-conditioning units, or high-pressure air start carts. That being said, this blog will cover APUs, how they work, and their importance.

For an aircraft to remain airworthy and safe to operate, it must meet stringent quality guidelines and regulations that focus on part conditions, maintenance, and approval. To prevent damage to various parts and systems and their subsequent failure, aircraft engineers take advantage of a process known as heat treatment. Generally, this process will cover a wide variety of parts ranging from landing gear components to the individual bearings and joints of assemblies, ensuring that they all perform with high reliability and integrity. In this blog, we will discuss the heat treatment of aircraft components, allowing you to better understand how such processes are carried out for a number of items.
