Junkers Jumo 004B-1

Junkers Jumo 004 Turbojet Engine

The Jumo 004 was the most widely used German WW II turbojet engine and was the first such German engine to go into quantity production. It had an eight stage axial flow compressor, six straight-through combustion chambers, and a single stage turbine. In its final production form, it developed a thrust of 1,980 pounds.

Preliminary design work began in 1937, but a full scale prototype was not bench tested until late 1940. A Jumo 004 was first flight tested in March, 1942, mounted on a Messerschmitt Me 110 aircraft.

Volume deliveries of 004s began in the fall of 1944 and when Germany surrendered in April, 1945, more than 5,000 of these engines had been produced. These were used to power the Me 262 twin jet fighter, the world's first operational jet combat aircraft, and the Arado Ar 234 series of bomber-reconnaissance aircraft.
