Abstract: The effect of main ingredients of high-energy propellants on combustion efficiency was studied by measuring the content of active aluminum in residue and vacuum explosion heat and conducting motor tests. The experimental results show that the kind and content of plasticizer are primary factors in affecting the combustion efficiency and the content of AP and the particle size distribution of solid ingredients also have a great effect on it. The real specific impulse efficiency of high energy propellants in the rocket motor(BSF-  315) tests is over 0.94.The real specific impulse data of high energy propellants in the rocket motor conditions were studied by the theory property prediction. The program can predict influences of the different burning rates and pressures in two kinds of standard testing motors (BSF - 165和BSF-  315)to the real energy property of high energy propellants.
