固体火箭发动机平均燃速预示

PREDICTION OF THE MEAN BURNING RATE IN SOLID ROCKET MOTOR

提出了用推进剂燃烧性能参数预示发动机平均燃速的思想。阐述了燃烧性能和燃烧环境的概念。导出了用推进剂燃烧性能参数预示发动机平均燃速的通用方法,并用试验数据对这一方法进行了验证。

It is proposed that the mean burning rate in solid rocket motor can be predicted by using propcllant burning performance paramc-ters,which depend on both propellant and burning environment. A feasible method for prediciting the solid rocket motor mean burning rate is discussed in the paper, and the resales are in agreement with the test data.
