Airframe Systems
P1 – State three purposes of pneumatic supply system for a typical piston engine powered light aircraft, and give the functions of the piston engine air compressor and receiver, within the system.
An aircraft powered by a piston engine usually tends to have a pneumatic air supply system. This allows the function of different systems on the aircraft that are essential to the flight of the aircraft.
In a newer system the supply system will provide a vacuum of air for the gyro’s, so that the de icing boots on the leading edge of the wings can inflate, for example, the boots on the jet stream wings inflate. The vacuum sometimes provides for some of the flight controls. An example of these flight controls would be the auto pilot system. The piston powered aircraft tend to consist of a receiver and a compressor. The compressor collects the air from the intake of the engine, creating a high volume of compressed air and storing it, acting like a storage tank. The receiver is there to make sure that the volume of air is consistent and smooth, else parts may move with too much force and damage themselves.
In modern day aircraft, the only pneumatic system used is there to drive the autopilot system and the gyros.
P2 – describe how air is supplied to the cabin pressurization system pre-cooler, for a typical passenger aircraft that’s powered by gas turbine engines, include in your answer where the air supply is taken off the engine
The cabin pressurization system is designed to keep the pressurization of the inside of the aircraft to a higher level than outside the aircraft, this is done by taking air from the ram stage of the gas turbine. This air is then supplied to the heat exchanger at minimum pressure. When the aircraft is in flight, the air is bled from the low pressure stage of the compressor, this supplies air to the aircrafts pneumatic systems. But when the aircraft is on the ground at a standstill, there is no pressurization in the gas turbine. The high
