FLOW REGULATOR OF SOLID-PROPELLANT ROCKET ENGINE NOZZLE Russian patent published in 2000 - IPC

FIELD: rocketry. SUBSTANCE: flow-regulator includes central body, drive for motion of this body and units for attachment of regulator to nozzle unit. Housing of central body is thin-walled in construction and is provided with tight partition in its inner portion which separates space where grain with low-temperature slow-burning charge is located from space where gear wheel setting the central body in motion is arranged. Wall of housing has through holes on lateral surface and in front portion. Inner volume of housing consists of two hermetic sections; each of them contains grains with low-temperature propellant charge. Ratio of mass of low-temperature grains to volumes of these parts increase with distance from regulator axis. EFFECT: reduction of level of thermal fluxes acting on structural members of regulator; reduced mass of base members of flow regulator and central body. 6 cl, 2 dwg
