Hans Joachim Pabst von Ohain

Born 14 Dec 1911; died 13 Mar 1998 at age 86.German aeronautical engineer who designed the first operational jet engine. Ohain, at age 22, conceived his theory of jet propulsion (1933) because to fly faster, airplanes could fly higher for lower air resistance, but there, propellers and piston engines worked badly. He saw turbojets as a solution, and took out his first patent on the gas-turbine jet engine in 1935, four years after Frank Whittle. By Sep 1937, Ohain had a hydrogen-fueled bench model producing a 250-km thrust. He designed the HeS3b turbojet engine that powered the first experimental jet aircraft, the He178, on its historic maiden flight at a top speed of about 350 mph on 27 Aug 1939, near Rostock, Germany. Whittle's first jet flew later, in 1941. His continued work on the gas-turbine engine during World War II resulted in abandonment of the centrifugal flow concept, and adoption of the axial flow compressor type engine. After WW II, Ohain worked for the U.S. airforce (1947-79). In 1945, he emigrated to the U.S. and became an engineer for the U.S. Air Force at its engine development centre. In 1956, Von Ohain became Director of the famed Air Force Aeronautical Research Laboratory.
