Control systems
Free-power turbine engine
Aerospace; Control systems
The turbine engine used by the Army. Sixty percent of the energy produced by combustion is extracted by the gas producer turbine to drive the gasproducer rotor. The rest of the energy is converted to ...
Foreign object damage
Aerospace; Control systems
Commonly called FOD, harm or destruction to the turbine engine caused by foreign objects sucked into the inlet area of the engine with the required air.
Fuel controls
Aerospace; Control systems
Devices to control fuel flow. They are usually hydromechanical and include speed governors, servo systems, valves, metering systems, and sensingpickups.
Front of engine
Aerospace; Control systems
End from which power is extracted. An exception is the T73 engine on the CH-54, in which the power is extracted at the end where the exhaust gas is expelled.
Fuel divider
Aerospace; Control systems
Device that metres fuel to the engine nozzles according to a predetermined schedule of secondary flow versus primary flow.
Frontal area
Aerospace; Control systems
Front part of a gas turbine engine, smaller than that of a reciprocating engine, therefore producing less drag.
Forged
Aerospace; Control systems
Shaped by hammering. Only the malleable metals are worked successfully. The application of heat increases plasticity.
