any object such as a tool, piece of equipment, engine part (nut, bolt, lockwire) that could in any way damage the engine.

Foreign object damage --
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.

shaped by hammering. Only the malleable metals are worked successfully. The application of heat increases plasticity.

Free-power turbine engine --
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 gas producer rotor. The rest of the energy is converted to shaft horsepower to drive the output shaft of the engine.

Frictional loss --
resistance to the relative motion of air flowing along a duct.

Frontal area --
front part of a gas turbine engine, smaller than that of a reciprocating engine, therefore producing less drag.

Front of engine --
