摘要： A system for providing pitch, yaw, and roll control during the flight of a rocket-propelled vehicle combines a vectorable nozzle with jet vanes. The vectorable nozzle provides yaw and pitch control, while the jet vanes provide roll control. Anti-rotation pins extend from the vehicle housing into longitudinal slots within the vectorable nozzle to allow vectoring movements and prevent rotation of the nozzle. The jet vanes are rotatably mounted on shafts within the nozzle exit cone to receive and guide combustion products passing through the nozzle. The jet vanes may be jettisoned after an initial high-angle-of-attack maneuver is completed and the vehicle gains speed, after which roll control is provided by aerodynamic fins. The jet vanes may also be formed of material which erodes after the initial maneuver, thereby reducing the loss of thrust caused by the jet vanes.
