Composite solid propellent and its production manner

摘要

PURPOSE:To increase the combustion rate without accelerating the curing reaction of the propellant by forming iron oxide as an additive to be added as a combustion catalyst for regulation of the combustion rate into a specific bar shape. CONSTITUTION:The bar-shaped iron oxide which has =1000 ratio of the length to diameter and has =10mu length and =0.01mu diameter is added to the composite solid propellant essentially consisting of a binder and oxidizing agent in the production of this propellent. The viscosity of the propellant is low and the pot life thereof increases in this way and, therefore, the productivity is improved. The productivity of the propellent decreases if the above-mentioned ratio of the length to the diameter is too large or if the length is too large. There is a tendency to a decrease in the increase rate of the combustion rate if the above-mentioned ratio is too small or if the length is too small. The resulted propellant is greatly increased in the combustion rate as compared to the propellant contg. the granular iron oxide. The amt. of the propellant to be used is consequently decreased.
