- Summary
- Junkers Jumo 004 B4
- Designed by Dr. Anselm Franz, the Junkers Jumo 004 was the world’s first mass-produced, operational turbojet engine. It was also the first turbojet in the world with axial-flow compressors, afterburning, and a variable area exhaust nozzle. The original 004 A model flew for the first time in 1942, but it was not suitable for production because it was too heavy and used alloys in short supply in Germany.
- The 004 B production model was easier to manufacture, weighed less, and used air cooling for the combustor, turbine blades, and exhaust nozzle. The engine powered the Messerschmitt Me 262, the first operational jet fighter, and the Arado 234, the first operational jet bomber and reconnaissance airplane. Volume production of the 004 B began in early 1944. Junkers manufactured nearly 6,000 Jumo 004 engines by the end of World War II.

- Key Accomplishment(s)
- Forerunner of the Modern Jet Engine
- Impact or Innovation
- Jet engines enabled aircraft to fly farther, faster, and at less cost than piston engine aircraft could.
- Brief Description
- This was the world’s first mass-produced turbojet engine. Germany built nearly 6,000 Jumo 004 engines by the end of World War II. Every jet engine in the world is derived from this axial flow design.
