Rolls-Royce Powers Up M250 for Bell 407, MD600

摘要

A new upgrade kit is available for the Rolls-Royce M250, which supplies power for the Bell 407 and MD600. The value improvement program (VIP) will lower fuel burn by 2 percent and raise hot/high performance by up to 5 percent, without increasing the weight of the engine, according to the company. Rolls-Royce received FAA certification for the upgrade-which incorporates modifications to the engine impeller and diffuser, using technology from the RR300 and RR500 programs-in late 2011 and will offer the kit to operators by the end of first quarter 2012.
