Fiber optic communication systems are revolutionizing our ability to transmit data, far surpassing conventional copper wiring and other transfer mediums in a number of ways. Utilizing lightwave technology to transmit data in the form of light, fiber optics are used to transmit voice, video, telemetry, and data over local area networks and long distances.

When an aircraft is parked at a terminal and is awaiting its next flight operation, it is crucial that servicing can quickly be conducted to ensure rapid turn-around times for maintaining tight airline scheduling. With the use of ground support equipment (GSE), various operations may be carried out while the aircraft is on the runway. Ground support equipment can serve many needs, including ground power operations, loading operations for passengers and cargo, aircraft mobility, and much more.

Gears are machine components that mesh with toothed parts to transmit torque, and they serve as a crucial part type for countless machinery equipment, vehicles, appliances, and more. Bevel gears in particular are a specific gear type that are used in applications where there is a need for changing the axis of rotation for a shaft. A bevel gear system can feature various bevel gear variations, though most are cone-shaped gears which transmit their power between two intersecting axes. Bevel gears are used in many powered tools and automotive assemblies, thus being aware of their common types and how they are used can be very beneficial.

Hydraulic power units (HPUs), a type of ground support equipment, are crucial for the testing and maintenance of aircraft systems. But like any machine, they cannot be used if they are not in peak condition. This is where preventative maintenance comes into play. By maintaining your HPU prior to its breaking down, you will be able to rely on it whenever you need it. In this blog, we will look at the four most important aspects of HPU maintenance: checking and changing oil, cleaning filters and strainers, checking for leaks, and lubricating the motor.

The aircraft radar system has become a critical asset to countless operations ranging from air traffic control to general navigation. Through their implementation and use, radars have increased the safety and operational efficiency of the entire industry. While some may be familiar with the basics of radar technology, others may not be aware of how they are used for aviation and what benefits they can provide.

Temperature sensors have a wide range of uses in many different applications. Some devices, like the equipment used to produce life-saving medicine, require highly accurate and responsive temperature sensors. On the other hand, applications like the thermometer in your car do not need to be as accurate or responsive. As such, there are many types of temperature sensors with varying accuracy and responsiveness. The four most common types of temperature sensors are negative temperature coefficient thermistors, resistance temperature detectors, thermocouples, and semiconductor-based sensors.

Since the advent of aviation, a great number of aircraft engine types have come about to achieve heavier-than-air flight. With types such as the turboprop engine, radial engine, and other combustion engines all common to aviation, a variety of aircraft with varying applications and designs may be accommodated for. The radial engine in particular is one of the oldest forms of aircraft engines, and it can still be found on a number of models to this day. Due to its importance and continued use for general aviation, understanding the radial engine’s functionality and make-up can assist in the operation and maintenance of such engines.

The role of an aircraft fuel system is to store fuel and supply it to the engines and auxiliary power unit. Aviation fuel is converted into heat energy and subsequently kinetic energy in the engine to power an aircraft. All engine-powered aircraft must have a fuel system onboard, the basic requirement of which is to provide a continuous flow of uncontaminated fuel to the engines at a pressure and flow rate to sustain operation at any attitude. The aircraft fuel system is not a single system, but rather a collection of various subsystems. The exact configuration varies from aircraft to aircraft, but the basic principles remain the same.

A pneumatic system is a power transmission system that uses compressed air as a working fluid similar to the way hydraulic systems use liquids. Hydraulic systems are more popular, but there are many advantages to using its pneumatic counterpart to transmit power. The principles in using air are the same as those in using hydraulic fluids, but the results are quite different.
