ABSTRACT:
The Invention is a rotary-wing aircraft having at least two vectored thrusters that may be tilted from a horizontal to a vertical position and to positions intermediate between the horizontal and vertical positions. The two vectored thrusters are equipped with propellers having separately variable pitch. The two vectored thrusters also are equipped with vanes having selectable vane angles to direct separately the air flow from the two vectored thrusters. A control system detects the flight condition of the aircraft and selects vectored thruster control settings corresponding to the detected flight condition and consistent with predetermined control rules to provide lift, thrust, yaw moments and roll moments.
