Abstract: An aircraft features a nose mounted propeller on a fuselage having a typical helicopter rotor assembly. The propeller axis of rotation is tilted upward from the longitudinal axis of the fuselage so that its rear face points downward. By reducing the amount of lift and forward thrust needed from the main rotor, the propeller allows greater forward speeds as the angle of attack on the rotor's blades can be kept low to avoid the stalling and violent vibration experienced by conventional helicopters at relatively high speeds. By greatly reducing the amount of thrust produced by the main rotor but still using it to generate lift, the addition of wings can be avoided. The aircraft can be flown in a forward direction in a generally horizontal orientation, as the nose does not have to be pitched downward to create thrust from the main rotor.
