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 ...

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.
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 ...
By January 1950 several additional engines had joined the program, bringing the total running time to over 1,000 hours, and a thrust of 26,490 N (5,960 lb f), making it among the most powerful engines of the era. The BMW 003 that it was developed from provided only 7,800 N (1,800 lb f), less than a third of the Atar.
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 ...
During World War II, a boxer-twin engine called the "Riedel starter" was used as a starter motor/mechanical APU for the early German jet engines, such as the Junkers Jumo 004 and BMW 003. Designed by Norbert Riedel , these engines have a very oversquare stroke ratio of 2:1 so that they could fit within the intake diverter, directly forward of ...
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 ...
