Whittle, a Royal Air Force mechanic in Cranwell in the west of England, and von Ohain, a physics student at Göttingen, were both in their early 20s when they started contemplating a flight propulsion process involving continuous compression. Neither knew about the other’s thoughts. Whittle applied for a patent for a turbojet in 1932, but it was not until four years later that he found sponsors to begin his first experiments. His engine ran for the first time in a test cell in 1938. A professor at university introduced von Ohain to aircraft manufacturer Ernst Heinkel in 1936. He and his mechanic Max Hahn found the perfect place to pursue his ideas at Heinkel’s plant. Patented in 1937, their experimental H S 3B engine took to the skies on its maiden flight on August 27, 1939. Evidently impressed, the German Ministry of Aviation decided to support the new technology.
Both von Ohain and Whittle emigrated later to the USA. They met there in 1978, traveled together on lecture jaunts, and in 1991 received the Charles Stark Draper Prize, a sort of Nobel Prize for Engineers, for their achievements.
The He S 3 was destroyed during World War II. MTU Munich’s apprentice workshop built two replicas in the 1980s, one for the Deutsches Museum in Munich and another for the Smithsonian Institution in Washington D.C..
