交付固体火箭发动机内弹道性能的预测技术

A TECHNOLOGY FOR PREDICTING INTERIOR BALLISTICS AND PERFORMANCE OF SOLIO ROCKET MOTORS

介绍了交付的固体火箭发动机内弹道曲线及性能的一种预测技术。该技术采用“无因次时间”和“有效燃速”概念，并充分利用发动机研制过程中积累的统计信息，故能较准确地预测发动机内弹道曲线、性能参数及其偏差范围。飞行试验的遥测数据表明：由该技术所预测的结果是可信的。

This paper introduces a technology for predicting interior ballistics and performance ofsolid rocket motors in delivery state. The concepts of 'nondimensional time' and 'effective burningrate' are presented and the statistic data accumulated in developing process of motors are fullyutilized, so it can exactly predict a deviation range of interior ballistics and performance of motors. Thetelemetric data from night test indicate that the results predicted with this technology are reliable.
