摘　　要：固体火箭发动机壳体缓释技术是提高固体火箭发动机服役安全性的重要技术手段之一。文章梳理了国内外固体火箭发动机壳体缓释技术方面的研究进展,根据各技术能够提供的排气泄压通道面积大小,将壳体缓释技术分为整体失强、头/筒分离和局部排气三大类,系统地对比了各项技术的设计思路、工作原理和实用效果。结合国外地地导弹、空空导弹和舰空导弹等导弹发动机壳体缓释技术应用实例和低易损性试验结果,阐明了壳体缓释技术对固体火箭发动机服役安全性的提升作用。最后,给出了使用发动机壳体缓释技术进行安全性总体设计的设计思路,并提出了固体火箭发动机安全性设计中应重点考虑排气通道临界面积和排气通道开启时刻两个关键因素。文中所述的研究进展可为固体火箭发动机服役安全性设计和优化提供参考。Mitigation techniques for solid rocket motor case is one of critical techniques to improve the service safety of the solid rocket motor.In this review,the progress of mitigation techniques for IM solid rocket motors was summarized.The mitigation methods were classified by venting area into three categories:the overall burst,the head/cylinder separation and the local venting.The de?sign methodology,working principles and practical effects of various techniques were compared systematically.The effect of mitiga?tion techniques on the service safety of solid rocket motor was clarified through the application examples of the ground?to?ground missile,air?to?air missile and ship?to?air missile rocket motors of foreign countries.Finally,the methodologies of mitigation design for the solid rocket motors safety were given and two key factors,namely the critical venting area and the critical opening time in safety design were put forward.This review could provide a reference for the design and optimization of solid rocket motor service safety.
