高氯酸铵降感技术研究进展

在高燃速推进剂研制过程中，添加超细高氯酸氨(AP)可大幅提高燃速，但也带来机械感度升高的问题。分别从球形化AP及表面改性、包覆AP、AP复合物等几个方面综述了AP降感技术的研究进展。同时，对降感AP在推进剂中的应用情况进行了总结和分析。并指出，未来AP降感的重点研究方向为改善球形化超细AP的表面结构、对超细AP进行混合包覆及探索新型功能材料。以期为高燃速推进剂的安全研制提供参考。

Research Progress of the Desensitization Technology of Ammonium Perchlorate

During the development of high burning rate propellants, the burning rate can be greatly increased by adding superfine ammonium perchlorate (AP), but the mechanical sensitivity is also increased. The research progress of AP desensitization technology was reviewed from the aspects of spherical AP, surface modification of AP, coating AP and AP composite. At the same time, the application of desensitized AP in propellant was summarized and analyzed. It was pointed out that the key research directions of AP desensitization in the future are to improve the surface structure of spherical ultrafine AP, to mix and coat ultrafine AP and to explore new functional materials. It is expected to provide a reference for the safe development of high burning rate propellants.
