Abstract: In this paper, a method to optimize the performance of solid pro-pellants in a given system is presented. In the multicomponent system, specific impulse,density, volume fraction of solid components and oxygen balance factor are chosed as the parameters. With the orthogonal combinatory design and actif-ied regression analysis, a calculation model with high accuracy is proposed to relate the specific impulse to various components. The optimal composition for complex systems is obtained by using the desirability functions, thus the optimization of multi-object will be appropriately solved.
