aircraft engine

(aerospace engineering)
A component of an aircraft that develops either shaft horsepower or thrust and incorporates design features advantageous for aircraft propulsion.

Aircraft engine

A component of an aircraft that develops either shaft horsepower or thrust and incorporates design features most advantageous for aircraft propulsion. An engine developing shaft horsepower requires an additional means to convert this power to useful thrust for aircraft, such as a propeller, a fan, or a helicopter rotor. It is common practice in this case to designate the unit developing shaft horsepower as the aircraft engine, and the combination of engine and propeller, for example, as an aircraft power plant. In case thrust is developed directly as in a turbojet engine, the terms engine and power plant are used interchangeably.

Air-breathing types of aircraft engines use oxygen from the atmosphere to combine chemically with fuel carried in the vehicle, providing the energy for propulsion, in contrast to rocket types in which both the fuel and oxidizer are carried in the aircraft.

aircraft engine

An engine used or intended to be used for propelling aircraft. It includes superchargers, appurtenances, and accessories necessary for its functioning but does not include propellers. The main types of aircraft engines are reciprocating, gas turbine, turboprop, fan-jets, and ramjets. Normally referred to as an aeroengine.
