DEVICE AND METHOD FOR CONTROL OF SPACE VEHICLE LANDING Russian patent published in 1997 - IPC

Abstract RU 2097286 C1

FIELD: rocketry and space engineering; non-expendable space vehicles. SUBSTANCE: space vehicle includes landing power plant connected with case of space vehicle in its bottom portion, movable front aerodynamic shield and space vehicle stabilization devices. Landing power plant is provided with nozzles whose common throat section provides for escape of gas from periphery to center of bottom part of space vehicle. Front aerodynamic shield is provided with drives for motion along longitudinal axis of space vehicle from position of protection of bottom portion and power plant of space vehicle at descent in atmosphere to position at which aerodynamic shield forms common throat section of nozzles. Stabilization devices are made in form of mechanisms of turn of aerodynamic shield along pitching and yawing axes. Swivel interceptors are mounted on its outer surface. At landing, braking force is created in form of bottom thrust formed by centripetal escape of gas from nozzle throat section; bottom thrust is controlled by pitching and yawing through change of configuration of throat section due to change of position of movable aerodynamic shield; in rolling, control is effected through twisting the jet flow by means of interceptors. EFFECT: enhanced efficiency. 3 cl, 5 dwg, 1 tbl
