Hans Joachim-Pabst von Ohain conceived his theories of gas turbine power plants while an engineering student at the University of Gottingen in 1933. After receiving his doctorate in physics in 1935, he developed these theories into reality and constructed a working model of his first jet turbine engine. Von Ohain recognized that more sophisticated testing and development were essential before practical application was possible. He convinced Ernst Heinkel, head of the Heinkel Aircraft Company, to allow him to work at the Heinkel factory. This partnership produced the world's first true jet turbine aircraft, the Heinkel HE-178, powered by von Ohain's jet engine. The first flight of this aircraft occurred on August 27th 1939. His continued development of 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. In 1945, he immigrated to the United States and became an engineer for the U.S. Air Force at its engine development center where he continued his theoretical and experimental research in propulsion and energy and energy conversion. In 1956 von Ohain became director of the famed Air Force Aeronautical Research Laboratory, noted for propulsion and energy conversion research. Here he displayed the same analytical insight, initiative, and drive as in his turbo-jet development, generating new ideas and strong programs for basic and applied research. His accomplishments produced new approaches in such fields as the colloid-gas core reactor for propulsion and power generation, electrofluid dynamics, advanced diffusers and ejectors, dynamic energy transfer, and V/STOL aircraft.
Inducted in 1982.
