A washer is a thin plate with a hole in the middle that is used in tandem with a threaded fastener like a screw, bolt, or nut. The uses of washers can vary greatly, from helping distribute the load of a fastener to serving as a spacer, spring, wear pad, locking device, and to reduce vibration. The hole in the middle of the washer, known as the inner diameter, is usually half of the washer’s outer diameter, but this can vary greatly depending on the type of washer and its intended use.

It's incredible to think about all the ways air has been used by mankind. The importance of aircraft engine air/fuel mixture aside, another beneficial way air is utilized in the aerospace industry is through air compressed hydraulic systems. In this article, we will discuss a small yet key component of aircraft hydraulic systems, hydraulic fittings, and go over various types and uses or ways these fittings are applied.

When a GPS system’s service is interrupted, an aircraft’s Inertial Navigation System (INS) is there to save the day. This self-contained flight management system provides aircraft locale without the need for input radio signals from ground navigation facilities or transmitters. The location of an aircraft is continuously updated through calculations based on the forces experienced (altitude, velocity, direction, accelerations) by INS accelerometers. An interface control head is used to input a starting location and from there any movement force data recorded by an accelerometer is then used to calculate an aircraft’s location based on that starting point.  A minimum of two accelerometers are used, one referenced to the north and one referenced to the east. In older units (due to gravity), accelerometers are mounted onto a gyro-stabilized platform that averts the introduction of error. An accumulated error of less than one mile after one hour of flight is possible.

When readying aircraft for flight, one of the most important procedures is bringing the aircraft to a position on the taxiway for clearance. This procedure is often conducted by using pushbacks, or tugs, which are low profile vehicles that can move around aircraft to a desired position. This can be done to bring aircraft out of a hanger, or away from an airport gate. While many aircraft hold the ability to do this operation themselves, there are many possible risks as the aircraft would need to use reverse thrust, possibly causing damage to buildings, equipment, and more. As this method is not practical, utilizing tugs is highly beneficial for preparing aircraft for flight.

Forklifts are a significant component in the supply chain sector, as they’re found in virtually every warehouse in existence—and for good reason. They’re extremely useful in carrying and transporting heavy stacks of items from one to another. Without them, the supply chain process would be a much lengthier process. If you’re looking to invest in a forklift for your company, be sure to do your research first. There are many different categories of military forklifts, each of which require different certifications and are designed to meet specific demands. See below to read about the different types of forklifts available in the market.

Adhering to proper maintenance practices is of utmost importance in the aerospace industry. No aircraft is so tolerant of neglect that it is exempt from deterioration in the absence of inspection and maintenance programs. Corrosion, wear and tear, natural fatigue, and chance failures all contribute to the overall functioning and safety of aircraft.
