CONTROLLABLE ROCKET ENGINE Russian patent published in 1999 - IPC

Abstract RU 2135810 C1

FIELD: various-purpose rockets. SUBSTANCE: engine includes charge with progressive gas-formation surface to ensure increased density of filling the chamber. Continuous increase of area of circular critical section is ensured by motion of central body mounted in fixed cylinder secured in pre-nozzle portion of engine housing. Motion of central body is effected due to action of pressure forces on its outer portion. Required speed of motion determined by continuously increasing gas input is ensured by special shape of collapsible member made from pliable metal which is subjected to axial compression in the course of motion of central body; besides that, it is dampening. EFFECT: optimal law of change of pressure in chamber; increased power intensity of engine. 2 cl, 7 dwg
