- turboshaft engine
- A gas turbine engine that delivers power through a shaft to drive a transmission, which in turn operates something other than a propeller—normally the rotor of a helicopter. The maximum amount of heat energy is converted into torque to drive the shaft. Very little thrust from the reaction is produced by the exiting gas stream. A turboprop engine is a type of turboshaft engine, but a turboshaft engine is not always used to drive the propeller.A cross section of a turboshaft engine for rotorcraft.
