Jet engine

The Heinkel He 178 flies on turbojet power, ending the propeller's speed limit.

Frank Whittle patented the turbojet in 1930 and Hans von Ohain developed his independently; von Ohain's engine powered the He 178 on 27 August 1939. Jets could fly faster and higher than piston aircraft. They became the engines of military aviation and, from 1952, airliners.
