摘要

Success in rocket motor design depends significantly on knowledge of burning rate behavior of the propellant. Burning rate is a function of the propellant composition itself and can be modified by changing not only the oxidizer percentage, its particle size or the heat of combustion of the binder but also by the add of a burning catalyst. As it is known, the burning catalyst helps to accelerate or decelerate the combustion at the burning surface and increases or decreases the value of the propellant burning rate. The present study speaks about the influence of copper chromite particle size on the combustion process of a plastisol propellant, and the establishment of the corresponding combustion laws. The choice of copper chromite is because of its thermal and kinetic performances for the plastisol propellant. The burning rates were measured by the standard strand burners, called Crawford burners, in an inert atmosphere. The basic propellant consists of ammonium perchlorate and PVC binder 75/25 weight, and other kinds of propellants were prepared by the addition of 1 % of copper chromite with five different particle sizes.
