Abstract
A power take-off (PTO) system includes a spur pinion on a shaft, used to turn a sector face gear that is coupled to a surface to be turned, such as a jet vane in a rocket nozzle. These may be parts of a thrust vectoring system, with the PTO system used to connect to a control surface actuator for a control surface such as a fin. The mechanical coupling between the fin and the jet vane may enable steering of a flight vehicle such as a missile at both low speeds and high speeds, with the thrust vectoring by the jet vane effective at low airspeeds and the control surface movement used for steering at high airspeeds. The PTO system may be backward compatible with prior systems, while allowing a more direct connection between the control surface actuator and the thrust vectoring system, with a reduced number of parts.
