Rolls-Royce Launches M250 Engine Variant

Rolls-Royce has secured a commercial launch commitment for one new and two current aircraft applications, with a customer announcement expected at Heli Expo.

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 with a 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 and performance, using proven technology already demonstrated in the field. These include a 5% 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 2% and engine reliability is increased.

Greg Fedele, Rolls-Royce, Senior Vice President – Helicopters, says, “The newest evolution of the M250 engine will deliver improved power and reliability with reduced fuel consumption.”

“Both commercial and military customers will benefit from these improvements as we continue to evolve the proven legacy of the M250 engine.”

Rolls-Royce has delivered more than 31,000 M250 engines, with the fleet totalling over 223 Million flight hours.
