摘要:
A high acceleration high performance solid rocket motor grain (l0) such as for a ballistic defense missile or rocket-assisted projectile comprises a propellant material (l2) which includes a highly plasticized binder so that the grain has a solids ratio equal to at least about 95 percent. In order that the grain with such a solids ratio may have adequate strength and withstand high acceleration forces, a reticulated structure (l4) is embedded therein. A method of constructing a rocket motor having such a grain is also disclosed.
摘要:
A circular slit plate (10) having slits (12) therein that are symmetrically positioned and originate near the centre of the plate and extend radially toward the outer diameter thereof is used to deaerate solid rocket motor propellant (14) and to provide a uniform propellant flow distribution of ribbons (17) of uncured propellant during rocket motor casting.
