| Abstract: |
| The research progress of the high-speed water entry of the vehicle is reviewed from three aspects: theoretical research, experimental research and numerical simulation research. The study of water entry can be divided into three directions: water entry impact, water entry cavity's formation and evolution, and water entry trajectory. In the aspect of water entry impact, the theoretical calculation method, the numerical simulation method and the experimental research progress of water entry impact are summarized. In the aspect of water entry cavity, the formation theory and evolution model of cavity, the result of water entry cavity's experiment and numerical simulation are summarized. In the aspect of water entry trajectory, the experiment and numerical simulation of the stability of water entry trajectory are summarized. On this basis, the key directions of water entry research are put forward. |
