Diamond Aircraft’s Austro Engines has bench tested a new dual FADEC-controlled rotary aircraft engine, the AE80R, that aims to match a weight of 60 pounds with a power output of 80 hp. The engine has been in development for more than two years and builds on Austro’s experience with the AE50R 55-hp rotary engine but has differences in its internal design that incorporates a “no loss lubrication system.” The new engine is targeting the LSA and ultralight aircraft markets, and may also see use in unmanned aircraft. Austro Christian Dries, chairman and owner of Diamond Aircraft, which owns Austro, says the new engine “has no vibration” and is a good fit for weight-sensitive small aircraft.
According to Diamond, the dual FADEC system will keep fuel consumption at its lowest possible limits and the engine oil system will result in extremely low oil consumption, maximizing its efficiency. Austro Engine last summer pursued airframe manufacturers other than Diamond, seeking potential matches for its diesel engines, which it sees as a growing segment in European aircraft markets. The company already offers diesel and rotary style engines. Austro’s recent production of AE50-series rotary engines has been close to 125 engines per year.
