SOLID-FUEL ROCKET ENGINE CHARGE

摘要

FIELD: solid-fuel rocket engines and their charge. SUBSTANCE: rocket engine charge tightly fixed with casing and integral bottom is of cylindrical structure with central duct. It has tore front bottom. Annular projection is made on charge duct at front tore bottom end, its buttend surface being formed by two joined surfaces with curvature radii making up (0.02-0.05) and (005-0.01) of charge length. EFFECT: improved choice of horizontal-to-vertical ratio of fuel mass feed rate components to ensure its uniform flow over blind bottom surface on fuel mass feed end. 1 cl, 1 dwg
