多相云雾形成及其爆轰规律是固液混合燃料云爆战斗部结构设计的重要依据。本目针对固液混合云爆燃料铝粉-乙醚（Al-DEE），以奥克托今（HMX）为添加剂，开展不同环境条件下HMX-Al-DEE云雾形成过程和爆轰特性研究。首先，建立可视化分散性能测试系统，结合Fluent开展不同环境温度、压力和湿度条件下HMX-Al-DEE云雾形成过程和不同时刻燃料浓度分布规律研究，揭示环境参数对多相云雾形成过程的影响机制。然后，基于激波管开展不同组成HMX-Al-DEE云雾爆轰试验研究，通过正交分析和理论模型计算分析，获得组成对混合燃料爆轰压力和爆炸下限的影响规律。最后，基于激波管建立环境温度、压力和湿度可控的爆轰性能测试系统，在18种环境条件下开展HMX-Al-DEE云雾爆轰试验研究，揭示环境参数对燃料云雾爆轰特性的影响机制。本项目研究成果对先进云爆武器的发展和应用具有重要意义。

The formation and detonation mechanism of multiphase cloud is the important basis for the structure design of cloud explosion warhead, which is filled with solid-liquid mixed fuel. This project plans to select HMX as the additive for typical solid-liquid mixed fuel Al-DEE, to study the dispersion process and detonation characteristics of HMX-Al-DEE under different ambient conditions. Firstly, the visual dispersion performance test system and Fluent software are used to study the cloud formation process and concentration distribution at different time of HMX-Al-DEE under different ambient temperature, pressure and humidity, so as to reveal the influence mechanism of ambient parameters on the he formation process of multiphase cloud. Then, the cloud detonation performance of HMX-Al-DEE with different ratios is studied in the shock tube. Based on the orthogonal analysis and theoretical model calculation analysis, the influence mechanism of fuel composition on the detonation pressure and lower limit of explosion is obtained. Finally, based on the shock tube, the test system with controllable ambient temperature, pressure and humidity is established to conduct detonation tests of HMX-Al-DEE under 18 kinds of ambient conditions, and the influence mechanism of ambient parameters on the cloud detonation characteristics is revealed. This project has a great significance for the development and application of advanced cloud explosion weapons.
