Abstract:
An improved system for use in imposing directional stability on a rocket-propelled vehicle. The system includes a pivotally supported engine-mounting platform, a gimbal ring mounted on the platform and adapted to pivotally support a rocket engine, an hydraulic actuator connected to the platform for imparting thereto selected pivotal motion, an accelerometer and a signal comparator circuit for providing error intelligence indicative of aberration in vehicle acceleration, and an actuator control circuit connected with the actuator and responsive to error intelligence for imparting pivotal motion to the platform, whereby a relocation of the engine's thrust vector is achieved for imparting directional stability to the vehicle.
