Rolls-Royce RR300 family
Rolls-Royce RR300 active light-helicopter turboshaft family, designed as a piston-engine replacement for the Robinson R66 and other general-aviation rotorcraft. The certified multi-fuel engine covers roughly 240–300 shaft horsepower, uses a two-stage gas producer and power turbine, and is supported by a 2,000-hour Preventative Maintenance Inspection philosophy; Rolls-Royce reports 1.7 million flight hours and continuing FIRST Network support. Exact RR300B1 and other marks, aircraft installations, and operator relationships remain separate identities.
