FIELD: machine building.
SUBSTANCE: invention relates to the field of rocket equipment, namely to design of powder pressure accumulator used as source of working medium for supply of system of gas-dynamic correction of motion of fanned jet projectile, located in forward part of jet projectile at distance from its centre of mass. Powder pressure accumulator comprises housing accommodating powder charge, igniter, flow nozzle and gas distributing device. Powder charge is made in form of single-channel cylindrical grain with thickness equal to 0.2…0.4 of powder charge diameter, and powder charge channel diameter equal to 0.4…0.6 diameter of powder charge. From one end of powder charge there is cylindrical armouring with casting composition, and from other end of powder charge there is an armoring in form of body, formed by rotation of isosceles triangle with height of 0.05…0.07 of powder charge diameter relative to powder charge axis so, that degressive law of powder charge combustion is realized.
EFFECT: invention allows to reduce intensity of oscillatory process occurring after termination of operation of angular stabilization system.
