The Rolls-Royce RR300 is a turbine engine currently being developed for the light helicopter market. Rated at 300shp (224KW) at Take-off power, the RR300 is believed to be a scaled-down version of one of the latest versions of the Rolls-Royce Model 250.[1]

The original Model 250 was rated at a similar power level to that of the RR300, but over the last forty odd years, later models have become more efficient and produce substantially more power. For instance, the Model 250-C40, which has an overall pressure ratio of 9.2:1 at an airflow 6.1lb/s, develops 715shp. Scaling this engine (or a similar version) back to 300shp would yield a very compact engine, with scale effects only having a modest impact upon specific fuel consumption.[citation needed]

The new five-seat Robinson R66 light helicopter will feature the Rolls-Royce RR300 as a turboshaft engine. Rolls-Royce have also signed a Memorandum of Understanding with Schweizer Aircraft to discuss future applications of the new RR300 engine family. Since Schweizer produce both helicopter and fixed wing aircraft, Rolls-Royce probably intend to produce both turboshaft and turboprop versions of the RR300, as with the Model 250.[citation needed]

FAA type certification for the RR300 is expected by 2008, with production to follow.[citation needed]
