Abstract
An actuation system for controlling the steerable nozzle of a missile or like vehicle. The system comprises two essentially identical actuators mounted along a plane generally transverse to the missile axis and oriented orthogonally relative to each other about the missile axis for pivoting the nozzle through mutually orthogonal axes, thereby achieving omni-directional steering. Each actuator includes an elongated yoke plate extending about the nozzle for applying steering forces against a yoke seat circumferentially mounted on the nozzle. Each yoke plate is pivotably mounted at one end and driven laterally at the other end by a gearing mechanism affixed to the nozzle skin.
