高速射弹入水稳定性研究现状与分析

摘要

高速射弹入水稳定性研究是世界范围内的一大难题.详细地介绍了高速射弹入水稳定性在理论研究、实验研究方面的研究历程及成果,并对入水空泡的发展过程、入水冲击载荷与入水过程水动力、入水稳定性影响因素3个方面的研究现状逐一解读.此外,结合当前理论基础与实验、数值计算条件对高速射弹入水过程的研究难点进行了总结与分析.%Research on the stability of projectile high-speed water-entry is a big issue worldwide. This paper particularly introduces the research stages and results on the stability of high-speed projectile’s water-entry process in theoretical and experimental research. This paper introduces in detail the current state on the water-entry cavity development process; the water hydrodynamic impact load and the hy-drodynamic force of water-entry process; the factors affecting the stability of high-speed projectileˊs wa-ter-entry process. In addition, in combination with the current theory and test and the numerical calcu-lation conditions, summarized and analyzed were the research difficulties in the water-entry process of high-speed projectile in this paper.
