SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 1994 - IPC

Abstract RU 2018704 C1

FIELD: power plants. SUBSTANCE: during combustion of change in chamber, high-temperature combustion products act on the surface of the annular nozzle cowling and center body. Profile of nozzle cowling and center body is made of low-heat-conducting material which consists of layers of fabric with mutually perpendicular fibers. Density of material of cowling and center body reduces along length of nozzle, thus ensuring minimum loss of mass. Disks fasten layers of center body fabric, thus excluding separation of layers. EFFECT: increased specific impulse. 1 dwg
