航行体高速入水问题研究综述

Review of Vehicle’s High-Speed Water Entry

从理论研究、实验研究和数值仿真研究3个方面综述了航行体高速入水问题的研究进展。入水问题研究可分为入水冲击、空泡的形成演化以及入水弹道3个方向。在入水冲击研究方面,概述了入水冲击的理论计算方法、数值仿真方法以及入水冲击实验的研究进展;在入水空泡研究方面,概述了空泡的形成理论与形态演化模型、入水空泡实验以及数值仿真研究成果;在入水弹道研究方面,概述了入水弹道稳定性的实验、数值仿真研究情况。在此基础上,提出了后续入水研究发展重点方向。

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.
