SOLID PROPELLANT CHARGE Russian patent published in 2000 - IPC

Abstract RU 2145674 C1

FIELD: volley fire systems; rocket shells. SUBSTANCE: proposed charge has housing, protection-and- fastening layer, head semicharge with star-like channel, tail semicharge with cylindrical channel and end face cups. Inner diameter of arms of head semicharge star-like channel cross section is equal to 0.55-0.65 of diameter of tail semicharge channel. Minimum area of cylindrical ring section between end faces of heat and tail semicharges is equal to 0.08- 0.15 of summary area of burning sections of end faces of head and tail semicharges with diameters not exceeding diameter of minimum ring section. Summary area or burning surfaces of nozzle end face and outer surface of cantilever section of tail semicharge is 0.02-0.05 of charge burning surface to nozzle end face. EFFECT: provision of solid propellant charge with 8-10% increase in volumetric fill factor at preservation of spreads of output characteristics and reliability criteria in preset range of application. 3 dwg
