Control systems

Airbleed actuator

Aerospace; Control systems

Device that operates the interstage bleed system, to improve compressor acceleration characteristics by unloading small amounts of compressed air.

Air inlet

Aerospace; Control systems

Large, smooth aluminium or magnesium duct at mouth of engine which conducts air into the compressor with minimum turbulence and restriction.

Air density

Aerospace; Control systems

Total mass of air per given volume, the weight of a given volume of air. Air is denser at lower altitude, at lower temperature, and lower humidity.

Air-fuel ratio

Aerospace; Control systems

Ideal mixture of 15 parts of air to 1 part of fuel by weight; the mixture to be burned in the combustion chamber.

Ambient

Aerospace; Control systems

Condition of atmosphere existing around the engine, such as ambient pressure or temperature.

Airfoil section

Aerospace; Control systems

Cross section of an airfoil parallel to a specific reference plane.

Gearbox mounted on engine inlet housing and driven from the power shaft. Overspeed governor, fuel control part of the torque metre system, an individual pumping unit which, with the tachometer drive ...
