A jet aircraft (or simply jet ) is an aircraft (nearly always a fixed-wing aircraft ) propelled by jet engines ( jet propulsion ).
Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines and aircraft achieve maximum efficiency (see specific impulse ) at speeds close to or even well above the speed of sound. Jet aircraft generally cruise at faster than about M 0.8 (609 mph, 981 km/h or 273 m/s) at altitudes around 10,000–15,000 metres (33,000–49,000 ft) or more.
Frank Whittle , an English inventor and RAF officer, developed the concept of the jet engine in 1928, Hans von Ohain in Germany, a decade later developed the concept independently at the end of the 1930s. He wrote in February 1936 to Ernst Heinkel , telling him of the design and its possibilities. However, it can be argued that the English engineer A. A. Griffith , who published a paper in July 1926 on compressors and turbines, also deserves credit.
