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, 294 cc (17.9 cu in) 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 55 hp (41 kW) 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.
