The Rolls-Royce M250 engine line has amassed an impressive 223 million flight hours over the past 50 years of operation and has been continuously updated through a series of innovative design improvements during the lifetime of the program.
The M250 engine continues to be installed on new applications, including the latest variant – theM250-C47E – on the US Navy’s Northrop Grumman MQ-8C Fire Scout.
The US Navy has committed as the first military customer to incorporate the M250-C47E into the Northrop Grumman MQ-8C Fire Scout. Rolls-Royce has delivered a development engine to Northrop Grumman for a demonstrator aircraft for the Rapid Deployment Capability program.
The M250-C47E takes the outstanding performance of the -C47B/M and joins it witha Value Improvement Package (VIP) and a new, dual-channel Full Authority Digital Engine Control (FADEC). The engine design includes a similar mounting configuration to the -C47B/M models.
The new M250-C47E improves efficiency andperformance, using proven technology already demonstrated in the field. These include a five percent improvement in ‘hot and high’ power and a nearly eight percent increase in rated takeoff power to 700 shaft horsepower. Specific Fuel Consumption (SFC) is reduced by a typical two percent and engine reliability is increased.
The engine was delivered to Enstrom at a ceremony Feb. 22 at Rolls-Royce in Indianapolis, following completion on the Small Engine Assembly Line.
