Numerical Simulation of the Burning Rate Pressure Index of Nitramine Modified Double Based Propellants

YANG Dong,SONG Hong chang,LI Shang wen,CHEN Shu ling (Nanjing University of Science and Technolgy, Nanjing 210094,China)  
In this paper, a chemical mathematic model for the pressure index of nitramine modified double based propellants is presented , and the expression of pressure index is given. The pressure index can be calculated from propellant component by using this expresure. The results show a good agreement with both of the change regularity and the experimental data of pressure index. In the meantime, based on the basic model, the chemical structure factors which influence the pressure index are discussed.
