Vectorable nozzle having jet vanes

A system for providing pitch, yaw, and roll control during the flight of a tactical missile, comprising:

• a thrust vector control (TVC) nozzle for providing pitch and yaw control during flight of the missile, the TVC nozzle capable of being rotatably mounted and including a forward end, an aft end, and a longitudinal axis;
• a plurality of jet vanes mounted on the TVC nozzle at a location aft of the forward end of the TVC nozzle and positioned generally about the longitudinal axis of the TVC nozzle to receive combustion products passing through the TVC nozzle, each jet vane being rotatably mounted about a jet vane shaft attached approximately at the center of pressure of each respective jet vane such that the jet vanes may be positioned at an angle with respect to the longitudinal axis of the TVC nozzle, thereby providing roll control during flight of the missile;
• and
• a jet vane actuation mechanism, the jet vane actuation mechanism being in communication with each jet vane for controlling the angle at which the jet vane is positioned, the jet vane actuation mechanism configured to rotate the jet vanes about their respective jet vane shafts at identical angles such that the jet vanes substantially provide only roll control during flight of the missile.
