If the Army acquires it, all four services will operate fleets of tilt-rotor aircraft.
WebJul 7, 2011 · At high aircraft forward speeds, the retreating blade tends to stall and lose lift, because the rotor RPM cannot be increased without the advancing blade tip going faster than the speed of sound. Because of this problem, the ratio of aircraft forward speed to rotor tip speed, known as Mu, is limited to about 0.5 in helicopters and autogyros. A rotorcraft or rotary-wing aircraft is a heavier-than-air aircraft with rotary wings or rotor blades, which generate lift by rotating around a vertical mast. Several rotor blades mounted on a single mast are referred to as a rotor.
