A lightweight and drag-free yaw control system developed for a jet propelled aircraft is described. Emphasis is placed on providing aircraft attitude control at low flight speeds, at high angles of attack, and during spin. The control system is comprised of a vertical tail with a thrust augmented rudder and a thrust rudder tab. The jet exhaust stream is deflected by the thrust vectoring rudder tab in a sideward direction to the aircraft, producing a thrust vectored yawing moment and creating supercirculation about the vertical tail and thrust augmented rudder. Supercirculation, a thrust-induced aerodynamic phenomenon, generates lift without increasing drag, enabling the rudder to provide additional yawing force for attitude control.
