Combustion efficiency study and prediction of specific impulse of high-energy propellants

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-φ315) tests is over 0.94. The real specific impulse data of high energy propellants is the rocket motor conditions which were studied by the theory property prediction. The program can predict influence of different burning rates and pressures in two kinds of standard tests motor (BSF-φ 165 and BSF-φ315) to the real energy property of high-energy propellants.
