| 摘 要： | 提出了硝胺改性双基推进剂燃速压力指数的化学数学模型，给出了燃速压力指数公式。利用此公式，可由推进剂的组成直接计算不同压力下的燃速压力指数，其结果不但反映出压力指数的变化趋势，而且在数值上与实测值也十分一致。同时，从基本模型出发，讨论了影响推进剂燃速压力指数的化学结构因素。

| Abstract: | 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. |
