Part 2. Gas-Turbine Engine: engine that employs combustion hot-gas flow as the working medium by which heat energy is transformed into rotating mechanical energy. A gas turbine usually includes a compressor that pressurized air into a combustion chamber. The combustion products pass from the chamber through the nozzles to drive the turbine machinery. The rotating turbine drives the compressor and the external load, such as an electrical generator, or produces propulsive power such as an jet engine. A gas-turbine engine can be modeled using idealized thermodynamic cycles such as the Brayton cycle shown below.
