Rolls-Royce Launches Upgraded M250 Turboshaft Engine

Rolls-Royce launched the latest version of its M250 turboshaft engine, the M250-C47E, today on the eve of Heli-Expo. The new variant replaces the -47B and -47M and incorporates the value improvement package upgrade kit that Rolls Royce introduced last year, as well as a dual-channel Fadec. As a result, the 700-shp engine boasts a 5-percent improvement in high and hot performance over its predecessor, an almost 8-percent improvement in takeoff power, to 700 shp, and reduced specific fuel consumption.
