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 ...
They were supplied with an original Whittle W.1, and later, a captured Junkers Jumo 004. Their research demonstrated that water ingestion reduced power by about 20%, not entirely unexpected, but at the same time doubled fuel use, which was a surprise.
The first axial compressor jet engine in widespread production and combat service, the Junkers Jumo 004 used on the Messerschmitt Me 262A fighter and the Arado Ar 234B jet recon-bomber, burned either a special synthetic "J2" fuel or diesel fuel.
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 ...
[3] [4] The design was of a high-wing mostly conventional-looking aircraft that was powered by a pair of Junkers Jumo 004 turbojet engines, one being located underneath each wing. [ citation needed ] Arado estimated that the E.370 would possess a maximum speed of 780 km/h (480 mph) at 6,000 m (20,000 ft), an operating altitude of 11,000 m ...
109-004 Junkers Jumo 004 turbojet; 109-005 Porsche 005 short-lifespan cruise missile engine; 109-006 Junkers/Heinkel 006; 109-007 Daimler-Benz 007; 109-011 Heinkel HeS 011, key late-war German development turbojet (only 19 examples built) 109-012 Junkers 012 – developed into the Kuznetsov NK-12 turboprop engine; 109-014 Argus As 014 pulsejet
The first German jet engines built during the Second World War used a mechanical APU starting system designed by the German engineer Norbert Riedel.It consisted of a 10 horsepower (7.5 kW) two-stroke flat engine, which for the Junkers Jumo 004 design was hidden in the engine nose cone, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
