- Rolls-Royce RR500
The Rolls-Royce RR500 is a small American
turboprop engine being developed by theRolls-Royce Corp. for use in small aircraft.Design and development
The RR500 is a turboprop version of the
turboshaft Rolls-Royce RR300 being developed for use in the Robinson Helicopter Company's R66, now under development.Basic weight of the engine with accessories is 250 pounds (113 kg). The model produces around 400 shaft horsepower (298 kW) for takeoff and can produce 380 shp in continuous use. It will use
jet fuel which is widely used, rather than theavgas which is commonly required for aircraft in this power range. It also will require much less frequent maintenance thanpiston engine s of similar power.A model of the proposed engine (which has not yet received
FAA type certification) was demonstrated at the 2008AirVenture inOshkosh, Wisconsin .References
