Rolls-Royce Submits UltraFan Engine for Boeing's NMA
Rolls-Royce has proposed its UltraFan engine, which is still in development.

Rolls-Royce has submitted its UltraFan engine to power Boeing's New Mid-market Aircraft (NMA), sources close to the matter told AIN at the Farnborough Airshow. The British engine maker's chief executive, Warren East, told reporters Tuesday that the company had submitted proposals to Boeing. "They’ll continue to refine their requirements, and we’ll continue to see if we can address those requirements economically,” he said.
