- Company Profile:
A turbofan engine whose bypass ratio is between 2:1 and 4:1.
Industry:Aviation
A turbofan engine with the fan mounted behind the compressor section. The blades of an aft-fan are normally extensions of the free turbine blades.
Industry:Aviation
A turbojet or turbofan engine with the fan and/or exhaust nozzles mounted in such a way that they may be rotated in flight to produce forward, vertically upward, or rearward thrust.
Industry:Aviation
A turboprop engine in which the propeller reduction gears are driven by the same shaft that drives the compressor for the gas generator.
Industry:Aviation
A turboprop engine whose allowable output power is less than the engine is physically capable of producing.
Industry:Aviation
A twin-engine airplane with both engines mounted in the fuselage. One is installed as a tractor in the front of the cabin. The empennage is mounted on booms.
Industry:Aviation
A type of air and/or seal used around the main –shaft bearings in a gas turbine engine. The seal consists of a series of rotating blades that almost contact the seal land. A small amount of air flows between the seal and the land to prevent oil flowing past the seal.
Industry:Aviation
A type of air-breathing reaction engine used during World War II to power jet-propelled missiles. Fuel is sprayed into the combustion chamber and ignited. As the heated air expands, it closes the one-way shutter valve in the front of the engine and exits the engine through the nozzle at the rear. As soon as the pressure inside the combustion chamber decreases, air enters through the shutter valve and more fuel is ignited. The thrust is produced in a series of pulses.
Industry:Aviation
A type of automatic control system in which part of the output is fed back into the input.
