The Junkers Jumo 004 was a pioneering turbojet engine developed in Germany during World War II. It was the world's first series-produced turbojet engine, powering several aircraft, most notably the Messerschmitt Me 262, the first operational jet fighter. The engine featured a simple design with a single-stage centrifugal compressor and a single-stage turbine, allowing for efficient performance. With a thrust output of approximately 1,980 pounds, the Jumo 004 significantly improved aircraft speed and maneuverability. Its introduction marked a significant advancement in aviation technology, influencing future jet engine designs and contributing to the development of modern military and commercial aircraft.
