The jet engine generates forward thrust by drawing in air, compressing it, burning fuel in it, and expelling the resulting exhaust at high speed, rather than turning a propeller. Frank Whittle patented a turbojet design in Britain on January 16, 1930, though funding difficulties delayed his own engine's first flight until 1941. Hans von Ohain developed a turbojet independently in Germany, unaware of Whittle's work, and his engine powered the Heinkel He 178 to the world's first jet powered flight on August 27, 1939, nearly two years ahead of Whittle's own aircraft.
Facts
Patent or First-Use DateFrank Whittle's British patent for a turbojet engine, filed and granted priority January 16, 1930; Hans von Ohain's independent German patent followed in 1936, and von Ohain's engine achieved the first jet powered flight, on August 27, 1939. SignificanceThe jet engine made sustained flight at speeds and altitudes propeller aircraft could not reach practical, transforming military aviation immediately and, after the war, turning commercial air travel into a routine and increasingly affordable way to cross the world. 1 Material or Power Source Disputed
Year1930
1930 is the year of Whittle's British patent, the earlier of the two claims; von Ohain's independent German patent followed in 1936 and his engine flew first, in 1939, before Whittle's own aircraft flew in 1941. The Jet Engine

FAQs
Did Frank Whittle and Hans von Ohain know each other?
They met after the war, and Whittle came to accept that von Ohain's work was independent.
They did not know of each other's work while they developed their engines, but they met after the war. Whittle was at first angry, because he felt von Ohain had stolen his ideas. Von Ohain eventually convinced him that his work had been independent, and after that the two became good friends.
