The pace of new technology infusion in helicopter turbine engines is not slowing.
General Electric, Honeywell, Pratt & Whitney Canada and Rolls-Royce all have significant civil turboshaft development in progress. Turbomeca has no major program under way, apart from the (mostly military) Ardiden. But the French-based firm has precise views about future key technology advancements.

After years of quiet work, Rolls-Royce in March simultaneously announced improvements on the Model 250 and a new engine, the RR300. As its designation suggests, the latter engine generates 300 shp for takeoff and 240 shp in cruise. It will replace early, low-end versions of the 250, with which it shares a type certificate. The RR300 will propel Robinson’s first turbine helicopter, the R66.
