Superior Air Parts is taking direct aim at the market turf dominated by the Rotax 912 series piston engine with a 100 horsepower compression ignition diesel for experimental and light-sport aircraft called the Gemini 100.

The engine is a unique design adopted from a British-born aero diesel that’s been in development for more than a decade by a now-defunct company called Powerplant Developments. The ultra simplistic configuration features six horizontally opposed pistons housed in three cylinders, each sharing a common fuel injector and glow plug.
