- Definição2
- A form of gas turbine engine that uses one or more stages of turbines to drive a transmission, which in turn drives the rotor of a helicopter. A turboshaft engine extracts a maximum amount of the heat energy from the exhaust gas to drive the turbine connected to the transmission.

- Contexto
- Many helicopters use a turboshaft engine to drive the main transmission and rotor systems. The main difference between a turboshaft and a turbojet engine is that most of the energy produced by the expanding gases is used to drive a turbine rather than producing thrust through the expulsion of exhaust gases.
