SOLID PROPELLANT ROCKET CHARGE Russian patent published in 2003 - IPC

Abstract RU 2220311 C1

FIELD: rocketry. SUBSTANCE: proposed solid propellant charge contains housing, end face cups, protective-and-fastening layer, star-like channel in bottom part of charge with cylindrical and conical sections. Initial thickness of burning arch in area of charge nozzle and face is 0.2-0.5 e₁, bottom part of charge is made with cantilever section of length equal to 0.6-1.8 e₁ where e₁ is mean in charge length initial thickness of burning arch. Distance between cross section of charge with at maximum ratio of burning surface to said section to area of through section o channel in said section and bottom end face of change is 0.8-0.9 L where L is length of charge. EFFECT: reliable functioning of charge made of high-energy high-elasticity propellants at simultaneous increase of specific loading density. 1 dwg
