Turboshaft
A turboshaft is a type of gas turbine engine that converts fuel energy primarily into rotational mechanical power to drive a shaft, rather than producing direct jet thrust. This shaft power is most commonly used to turn helicopter rotors or marine propellers.
TECHNICAL DEFINITION
A turboshaft engine is an air-breathing gas turbine engine optimized to produce shaft horsepower for external mechanical loads, typically featuring a power turbine connected to an output shaft; it is predominantly utilized in helicopters, marine propulsion, and auxiliary power units (APUs) due to its high power-to-weight ratio and efficiency at driving rotating machinery.
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.
