Despite needing power for tests, turnovers, and other processes, engine operations can put surrounding individuals and buildings at risk with various safety hazards. As a result, operators must take advantage of either an Auxiliary Power Unit (APU) or an Aircraft Ground Power Unit (AGPU). Despite these options, some aircraft may not feature an APU, and APUs are loud during operation and utilize engine fuel. As such, the AGPU is the optimal option for powering aircraft electronics while the aircraft is situated on the ground.

Rotors are components that are found in various assemblies and machinery, used to transform electric or electromagnetic energy into rotational motion. In order for such equipment pieces to perform optimally, they must maintain an even balance and distribution of weight across their rotational axis. The unbalancing of weight on a single side can happen to rotating parts of any assembly, and uneven mass distribution will result in the misalignment of a component’s rotation center in regard to the geometric axis. This can deter proper efficiency and safety, and as thus proper balancing should always be maintained. With rotor balancing, noise, vibration, and other various issues can be deterred for the health of a system.

Aircraft tires, unlike the typical car tires, need to withstand an incredibly wide scope of temperatures that go from short 60 degrees Celsius at an elevation of 10,000 meters to very high temperatures when arriving on the ground. It is also important that airplane tires are treated with much more care than your ordinary vehicle tires. Airplane tires are tubeless, have a weight of approximately 12 to 18 bar, and are loaded up with nitrogen rather than simply air. At the point when every one of these factors are assembled, the outcome is that airplane tires should be changed after each 120 to 400 landings depending upon the airplane model and factors (for example, the runway, the climate, and the pilot).

There are some valid proponents and points made on the case for public and commercial aircraft travel. Some experts say that it is “better” for the environment or that it “produces less carbon emission” than if people were to use private air travel. Some yet claim that it is “elitist.” And while there may or may not be a semblance of reason to those points, here are some counterpoints that may well sway the opinion of the general public. In the case of public vs. private travel, there are many pros and many benefits that outweigh the few concerns and reservations that argue against it. Read on below for more information on private air travels and the different types of private air travel that are available.

Typical aircraft achieve flight with the use of an internal combustion engine that ignites air and fuel mixtures, generating propulsion and thrust. This process generates intense amounts of heat within the engine area, and the aircraft engine cooling system ensures that temperature can be kept at a level that protects components and maintains efficient operation of systems. The cooling system may be based on air or liquid cooling, or may be a combination of the two. Each also has their various advantages and disadvantages, and understanding these can make an investment decision easier.

Aircraft engines are an indispensable part of an aircraft, creating the ability for heavier-than-air flight for many planes, both small and large. They most often come in the form of piston engines and gas turbines, though some may be electric. In both piston engines and gas turbines, propulsion for flight is achieved through the combustion of fuel, and then the various engine parts work together to generate mechanical power. While aircraft engines are very advanced and well developed, they still face problems just like any other machine and are prone to failures over time with constant use. When these instances happen, it can pose issues affecting time and money to get them back up and running. While one could simply replace an engine, there are various benefits to having an engine rebuilt instead. In this blog, we will discuss some of the common reasons that engines fail, as well as the benefits of rebuilding them instead of replacing them.

When conducting inspections and maintenance of an aircraft, there are often two categories it can fall into. The first category is scheduled maintenance which is conducted annually, before flights, on timed intervals, or any other pre-scheduled time by the pilot and/or technician. The other type is unscheduled maintenance and is conducted whenever a problem arises and needs to be checked and solved. Understanding the two is very important for pilots for safe flight and preservation of their equipment.
