The Junkers Jumo 004 was the world's first series-produced turbojet engine, developed in Germany during World War II. It powered several aircraft, most notably the Messerschmitt Me 262, which was 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 1,800 pounds, the Jumo 004 significantly improved aircraft speed and maneuverability. Its introduction marked a pivotal moment in aviation history, influencing future jet engine designs and contributing to the development of modern military and commercial aircraft.
