摘要： 作者对小粒子组合模型(PEM)中的某些公式及参数进行了修改.在此基础上,计算了35组含铝丁羟推进剂的燃速,考察了氧化剂级配及催化剂等对推进剂燃速的影响.燃速计算值与实测值符合程度高,即90%的计算燃速值与实测值的相对误差在±10%之内.

Abstract: On the basis of the improved Petit Ensemble Model, the author calculated the burning rates of 35 group of aluminized HTPB propellant with or without buring rate modifier. The calculated results are in good agreements with the experimental burning rates. Ninety Percent of the calculated results are within the range of less than ±10% relative error.
