Jumo 004

The Junkers Jumo 004 was a German jet engine developed during World War II. It was the first operational axial-flow turbojet and became the most widely produced jet engine of the war. Developed by Anselm Franz, it powered the Messerschmitt Me 262 aircraft, which first flew in 1942. Unlike earlier centrifugal-flow engines, the axial-flow design allowed air to pass straight through the engine, offering advantages for higher speeds and efficiencies. The development of jet engines in Germany, alongside parallel efforts in Britain and the United States, marked the beginning of the jet age in aviation.123
