HIGH-PRESSURE RESERVOIR MADE FROM COMPOSITE MATERIALS Russian patent published in 1998 - IPC

FIELD: designing and manufacture of reservoirs, combustion chambers for solid-propellant rocket engines, chemical reactors and other objects working under conditions of stringent limitation of dimensional (in free and loaded states) and mass requirements. SUBSTANCE: bottom of plastic housing are provided with circular corrugation with convexity outside which increases initial volume of equilibrium bottom and enhanced adaptability of arrangement with adjacent units. When such envelope is loaded with internal pressure, bottom are deformed beyond convexity zone as standard bottoms - in equidistant pattern relative to initial profile and are not deformed in convexity zone at all or their deformation is low as compared with adjacent nonconvex zones. Thus, nonequilibrium initial bottom approaches equilibrium one in loading it with internal pressure without disturbing service characteristics of housing. EFFECT: enhanced efficiency. 1 dwg
