- Model of a Pratt & Whitney J-57 Turbojet Engine, circa 1958 - Pratt & Whitney introduced its J-57 turbojet engine in 1950. The versatile unit powered everything from Boeing 707 passenger airliners to B-52 bombers. Turbojets heat compressed air inside a gas turbine -- the turbine drives the compressor -- and expand the exhaust through a propelling nozzle, which provides thrust for the airplane. This electric-powered cutaway model illustrates the turbojet's operation.
