The Junkers Jumo 004 was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. Some 8,000 units were manufactured by Junkers in Germany late in World War II, powering the Messerschmitt Me 262 fighter and the Arado Ar 234 reconnaissance/bomber, along with prototypes, including the Horten Ho 229.
The 003 and the Junkers Jumo 004 were the only German turbojet engines to reach production during World War II. Work had begun on the design of the BMW 003 before its contemporary, the Jumo 004, but prolonged developmental problems meant that the BMW 003 entered production much later, and the aircraft projects that had been designed with it in ...
The HeS 30 (HeS - Heinkel Strahltriebwerke) was an early jet engine, originally designed by Adolf Müller at Junkers, but eventually built and tested at Heinkel.It was possibly the best of the "Class I" engines, a class that included the more famous BMW 003 and Junkers Jumo 004.
Initially, Junkers proposed modifications of the Jumo 004, specifically the 109-004G and 109-004H. However, these variants were rejected as they were not powerful enough, and Junkers began to design the 109-012. [1] The engine was to feature an 11-stage axial compressor enclosed in a sheet-steel casing and a 2-stage, air-cooled turbine.
E.g., the similar Westinghouse J30 (same type of engine, same type of age) has a thrust specific fuel consumption of 38 g/(kN⋅s) - which would make the Jumo 004 ten times more efficient. If Thrust-specific_fuel_consumption#Typical_values_of_SFC_for_thrust_engines is any guide, there's no such thing as a modern gas turbine working at anything ...

An interesting feature of all three German jet engine designs that saw production of any kind before May 1945 (the German BMW 003, Junkers Jumo 004 and Heinkel HeS 011 axial-flow turbojet engine designs) was the starter system, which consisted of a Riedel 10 hp (7.5 kW) flat twin two-stroke air-cooled engine hidden in the intake, and ...
It was designed as a single-shaft, single-flow turbojet. The basic conception was a further development of the design already applied with high perfection on Junkers Jumo 004 and Junkers Jumo 012, as well as the BMW 003 and BMW 018 engines. In this design, the compressor, combustion chamber and turbine are traversed in axial direction by the ...
