Applications

Probably the best known application of the Brayton cycle is the jet engine. The jet engine is widely used in aviation because they are relatively lightweight and are capable of huge power output. The basic jet engine relies on the high pressure and temperature turbine exhaust to provide thrust. The jet engine can also be outfitted in several configurations to power anything from helicopters and generators to military tanks.

The above cycle is a turboprop engine; the Turbine is directly connected to an output shaft that turns a propeller. Advancement in propeller design has allowed turboprop engines to achieve better efficiency than a turbofan engine (common passenger jet engine) under certain conditions.
