摘要:

叙述了某地空导弹在训练打靶中的一些飞行异常现象。对服役多年的固体火箭发动机（ＳＲＭ）的内弹道异常，从双基推进剂装药老化、喷喉截面调节、装药碎块喷射以及裂纹燃烧等方面进行了分析。对服役期的双基推进剂固体火箭发动机的使用维护和作战训练有一定参考价值。

Abstract:

his paper deals with several flying ballistic anomalies in the targetpractice for some types of ground-to-air missiles. The internal ballistic anomalies insolid rocket motors (SRM ), having been in term of service for many years, are analysed in respect to ageing of double base propellant grain, adjustment of nozzlethroat area, mass ejection and crack burning, which will be great helpful in the employment and maintenance of SRM during the term of service as well as the targetpractice.
