A redistribution of metal loaded into the propellant grain is one of the methods to decrease the specific impulse loss. This paper reports on the ways to obtain the optimum metal particle disposition for the case-bounded propellant grain of tube cross-sectional type. Three different approaches to analyze the metal combustion efficiency are discussed. The influence of the dynamic non- equilibrium of two phase flow on the optimum metal particles disposition in the propellant grain of tube cross-sectional type is investigated.7 pagesPDF© 2014 University of Pretoria.
