Abstract

A commonly assumed operational requirement for a multi-rotor vehicle, often referred to as a “Quad-Copter” or “Quad-Rotor”, is to have onboard a minimum of three motors, in order to provide a stable hover, and more frequently as many as eight motors. The Twin Propeller Attitude Control (TPAC) Air Vehicle, using a hybrid stabilization system, needs only two motors, in order to achieve full control of altitude, pitch, roll and yaw. Pitch control is achieved by means of differential thrust, while roll and yaw control is accomplished via thrust vectoring. In the event of loss power of one or both engines, a parachute will be automatically released.

Claims

3-1. The Twin Propeller Attitude Control Air Vehicle of claim 1, wherein each engine assembly can be tilted around the longitudinal axis in opposite directions, thereby creating a yawing moment, resulting in heading control.
