Norbert Riedel

Norbert Riedel (* 1 April 1912 in Jägerndorf, Sudetenland, then Austria-Hungary; † 24 February 1963 in Zürs am Arlberg, Austria) was an engineer and entrepreneur.

The starter system, which consisted of a Riedel 10 hp (7.5 kW) two-stroke flat engine hidden in the intake, essentially functioned as a pioneering example of an auxiliary power unit (APU) for starting a jet engine.

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 component instead.

In 1947, he founded the Riedel Motoren AG in Immenstadt, where he designed the light motorcycle Imme R100 which was manufactured in series.

The "Peggy" was provided with a novel electromagnetic pushbutton circuit, electric starter, fan cooling and a propulsion unit swingarm.
