本项目拟建立一套完整的单滴高速雨滴撞击试验测试方法，针对光学镀膜材料、C/SiC复合材料、树脂基复合材料等典型非均质材料，开展高速单滴雨滴撞击试验，研究典型材料在高速雨蚀过程中的动态响应行为，探索应力波在高速雨滴撞击过程中的传播规律，揭示材料的雨蚀失效及破坏机理，建立材料的损伤破坏判据，明晰高速雨滴撞击过程中液滴大小、形态、入射角度等因素对材料破坏的影响规律。研究成果不仅有助于推动高速冲击下的流固耦合问题研究的发展，为研究雨蚀过程中的科学问题解决奠定基础，还能够为诸如高超音速飞行器的热结构材料及风力发电机和航空发动机先进复合材料风扇叶片的雨滴撞击危害评估及抗雨蚀设计等提供技术支撑。

In this project, a set of single droplet impact test method will be established. Aiming at typical materials, high speed droplet impact experiments are carried out. The dynamic response behavior of typical materials during droplet impact is studied, and the propagation law of stress wave during impact is explored. Failure mechanism of droplet impact are revealed. The damage criterion of droplet impact is established. The influence of various factors such as the size, shape and impact angle, on heterogeneous materials are clarified. The research results not only contribute to the development of fluid-solid coupling problem under high velocity impact. It lays a foundation for the study of solving scientific problems in the process of rain erosion. It can also provide technical support for raindrop impact hazard assessment and rain corrosion resistance design of wind turbine and advanced composite fan blades for hypersonic aircraft.
