초록

An improved method of operating rotorcraft capable of achieving high speeds such that stability is maintained as the craft speed exceeds 0.75 times the rotor tip speed. These high speeds are achieved by varying collective pitch, including to negative values, to maintain acceptable levels of flapping at high aircraft forward speeds and low rotor rotation rates, or adjusting or maintaining the rotor rotation rate by automatically controlling the tilt of the rotor disk relative to the airstream or aircraft, or a combination of these techniques. More specifi...

1. A method for controlling an aircraft during horizontal flight, the aircraft having a fuselage, wings attached to the fuselage, a rotor mounted to the fuselage for rotation in a plane of rotation, the rotor comprising at least two blades, each blade having a tip, and a power source that delivers forward thrust for horizontal flight, comprising:providing sufficient thrust from the power source to cause airflow over the wings to provide forward horizontal flight at a desired velocity, the wings being sized to provide enough lift to sustain the horizontal...
