The NSU Delphin III streamliner motorcycle set the motorcycle land speed record in what year, the engine used an unusual rotary supercharger related to NSU's eventual development of the Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion?
NSU Delphin III The NSU Delphin III streamliner motorcycle set the motorcycle land speed record in 1956. Wilhelm Herz rode the machine to 211.4 mph at Bonneville Speedway in Utah, to break 200 mph (320 km/h) for the first time. Its fairing, designed in a wind tunnel at University of Stuttgart (then Stuttgart Technical College), gave it a drag coefficient of 0.19. The same engine powered Herz to a 1951 world speed record, with a less efficient frame/fairing, the "Delphin I". The engine used an unusual rotary supercharger related to NSU's eventual development of the Wankel engine. In the supercharger, both a trochoidal inner rotor and epitrochoidal outer rotor spun around a stationary shaft.
DC motor A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
