Control systems
Stator
Aerospace; Control systems
Part of assembly that remains stationary with respect to a rotating part. Stator vanes are a stationary set of airfoils in a compressor.
Thermodynamic cycle
Aerospace; Control systems
Succession of processes which involve changes in temperature, pressure, and density in which the substance acts as a means of transformation ofenergy. See Otto and Brayton cycles.
Test cell
Aerospace; Control systems
Building, usually concrete, that contains both a control room and an engine room, used for testing engines. The test cell is at the manufacturer's; a mobile engine-test unit is used in the field.
Thrust, net
Aerospace; Control systems
The effective thrust developed by the engine during flight, taking into consideration the initial momentum of the air mass prior to entering theinfluence of the engine.
Thrust, reverser
Aerospace; Control systems
A device used to partially reverse the flow of the engine's nozzle discharge gases and thus create a thrust force in the rearward direction.
Tachometer generator
Aerospace; Control systems
Device that supplies power at a frequency proportional to the driven speed which drives the synchronous motors in the indicator.
Thrust, specific fuel consumption
Aerospace; Control systems
The fuel that the engine must burn per hour to generate 1 pound of thrust.
