The Junkers Jumo 004B series of turbojet engines were the world's first mass produced jet engines and powered numerous jet fighter & bomber designs in the closing stages of the war; most of these designs never actually reaching any production level other than prototype. Production aircraft such as the Me262 and the Arado Ar234 bomber were the only real beneficiaries of this revolutionary design. 

The Arado design later switched to using the newer BMW003A turbojet in order to relieve the already limited Jumo production, and help the Me262 program. The Me262 did actually fly using the BMW turbojet (R series) in 1944, but performance was stunted badly, thus being abandoned. The BMW powerplant went on the power the Heinkel He162 Salamander interceptor & fighter.


Basically the 004B was designed around an Axial airflow compressor, 6 combustion chambers, and a single stage turbine. All these features can be seen on the original Junkers drawing below.
