Design and development The AE50R is based on the MidWest AE50. Diamond Aircraft Industries purchased the design from Mid-West Engines Limited on 10 March 2003 and took over as the type certificate holder. Diamond formed its subsidiary, Austro Engine, to produce the engine.
The engine is a single rotor four-stroke, air and liquid-cooled, gasoline Wankel engine design, with a mechanical gearbox reduction drive employing a helical gear set with a reduction ratio of 3.225:1. Cooling is predominantly liquid, with forced air cooling for the rotor core. A starter and generator are standard equipment. It employs dual capacitor discharge ignition with variable ignition timing and produces at 7750 rpm.
The engine was originally type certified by Mid-West on 18 Dec 1992 to JAR-22 H, Change 4, dated 13 September 1982, incl. Orange Paper 22/90/1. It was transferred to an EASA Type Certificate under EASA Part 22 Subpart H on 4 April 2011.
