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 second prototype (Junkers Ju 287 V2) would have had six engines (originally four underwing BMW 003s and two fuselage-mounted Jumo 004s, but later changed to two triple clusters composed of four Jumo 004s and two BMW 003s), and also differed from the Ju 287 V1 in having the main undercarriage struts with an inward cant, the horizontal ...
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 ...
Anselm Franz (January 21, 1900 [1] —November 18, 1994) was a pioneering Austrian jet engine engineer known for the development of the Jumo 004, the world's first mass-produced turbojet engine by Nazi Germany during World War II, [2] and his work on turboshaft designs in the United States after the war as part of Operation Paperclip, including the Lycoming T53, [2] the Honeywell T55, [3] the ...
Seven fuel tanks were housed in the two-spar wing and dive brakes were positioned on its upper surface. The main wheels of the tricycle landing gear retracted into the wings while the nose gear retracted into the lower part of the nose. [1] The Jumo 004 turbojet, captured from the Germans, had 8.8 kilonewtons (1,978 lb f) of thrust.
This, in turn, can translate into price. For instance, costing 10,000 ℛℳ for materials, the Jumo 004 proved cheaper than the Junkers 213 piston engine, which was 35,000 ℛℳ, [31] and needed only 375 hours of lower-skill labor to complete (including manufacture, assembly, and shipping), compared to 1,400 for the BMW 801.

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 ...
