ROCKET-PROPELLED VEHICLE Russian patent published in 2013 - IPC B64G1/40 F02K9/00 

FIELD: transport.

SUBSTANCE: invention relates to rocketry. Proposed vehicle comprises body, rocket engine with axially symmetric supersonic nozzle and truncated cone-shaped jacket made of soft thin-wall material, closed on body side and exposed on nozzle side to fold along lengthwise axis. Cone smaller exposed base extends beyond nozzle edge. Case is made form heatproof dense fabric. Fabric of smaller exposed base is connected with heatproof rigid ring. Jacket larger closed base has annular tubular channel communicated on one side with flexible tubular channels from heat-resistant dense fabric bound with jacket fabric and located along jacket one generatrix extending from larger base to smaller one and provided with gauged outlets in rigid ring area and, on the other side, with high-temperature gas source. Folded jacket is attracted to body by cords from thermally unstable material jointed with jacket smaller base rigid ring and located opposite flexible tubular channel outlets.

EFFECT: decreased weight and increased thrust.
