Integral injection thrust vector control with booster attitude control system

摘要

A projectile includes a propulsion booster for producing pressurized gases, a nozzle for expelling the pressurized gases produced by the booster, and a supplementary integrated actuation system. The integrated actuation system selectively directs propellant from a storage reservoir of the integrated actuation system through an interiorly-located outlet of the integrated actuation system located at the nozzle and into the nozzle, thus changing a direction of the pressurized gases expelled by the booster. The integrated actuation system also selectively directs propellant from the storage reservoir through a peripherally-located outlet of the integrated actuation system, to produce thrust at an external periphery of the projectile, thus diverting the projectile. The integrated actuation system may also selectively direct propellant to a nozzle actuation system for positioning the nozzle, to a stage separation system for separating portions of the projectile, or to a power generator for generating electric power for the projectile.

1. A projectile comprising:
a propulsion booster for producing pressurized gases; a central longitudinal axis that extends through the projectile; a nozzle for expelling the pressurized gases produced by the booster, the nozzle having a nozzle wall defining a thrust passage for directing a thrust plume of the pressurized gases expelled by the booster, wherein the nozzle wall has an interior surface that faces radially inward towards the axis, wherein the projectile has an exterior surface disposed substantially opposite the interior surface of the nozzle, and wherein the exterior surface faces radially outward away from the axis; and a supplementary integrated actuation system for storing and directing propellant, wherein the integrated actuation system selectively directs the propellant from a storage reservoir of the integrated actuation system to an interior outlet generally disposed near the interior surface, thus changing a direction of the thrust plume, and wherein the integrated actuation system selectively directs the propellant from the storage reservoir to a an exterior outlet generally disposed near the exterior surface, to produce thrust at an external periphery of the projectile, thus diverting the projectile.
