// PROPULSION SYSTEMS AND ENGINE TECHNOLOGY TERM
Turboprop
A turboprop is a type of aircraft engine where a jet engine's power is primarily used to spin a propeller, which generates most of the thrust to move the aircraft. It is known for its fuel efficiency at lower speeds and altitudes compared to jet engines.
TECHNICAL DEFINITION
A turboprop engine is an air-breathing gas turbine engine that converts the energy from burning fuel into rotational power to drive a propeller through a reduction gearbox, generating the majority of thrust for aircraft propulsion while also providing a minor amount of exhaust jet thrust, making it highly efficient for subsonic flight at lower altitudes.
BACKGROUND
General Electric Company, doing business as GE Aerospace, is an American aircraft engine supplier that is headquartered in Evendale, Ohio, outside Cincinnati. It is the legal successor to the original General Electric Company founded in 1892, which split into three separate companies between November 2021 and April 2024, adopting the trade name GE Aerospace after divesting its healthcare and energy divisions.
