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.
It was produced in Victoria in Nuremberg and served as a starter for the operational German Junkers Jumo 004 and BMW 003 jet engines, placed on the centreline of each of these, and was also meant for use on the Heinkel HeS 011 experimental jet engine, but relocated above the intake passage within a Heinkel-designed prefabricated sheet metal ...
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 essentially ...
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.
The BMW 003 utilized nearly the same starting method as its slightly more powerful Jumo 004 competitor: one of Norbert Riedel's 10 PS flat-twin two-stroke engines, installed within the engine's intake diverter as a mechanical APU, to get the 003's central shaft rotating for operation. An American military-authored post-war review of the BMW 003 ...

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 ...
