gas turbine engine

gas turbine engine
An internal combustion engine where high energy is released from the fuel in a constant-pressure cycle. It has a turbine rotated by expanding hot gases. In its usual form, it consists of a rotary air compressor with an air intake, one or more combustion chambers, a turbine-driven compressor, and an exhaust outlet. Some gas turbine engines use additional stages of the turbine to drive devices such as fans, propellers, rotors, generators, or pumps.
