- 摘要超空泡状态下的航行体水下弹道的研究涉及固、液、气（汽）三相介质的运动。
The study of underwater trajectory and motion stability of supercaviting bodies, dealing with three kinds of media-solid, liquid, gas (vapor), is one of the most important problems in mechanics and engineering. - 本文应用细长体理论计算航行体在超空泡状态下的流体动力，成功类比了超空泡状态下的航行体水下弹道。
In this paper, the theory of slender bodies was used to calculate hydrodynamic forces and to numerically simulate the underwater trajectory of supercaviting bodies, the motion stability of supercaviting bodies was analyzed, too. - 文摘:针对旋转弹体高速入水特点，从弹体运动的动力学方程和相似理论出发，提出了模拟旋转弹体高速入水水中弹道的马赫相似实验方案.该方案在大气环境条件下，能够实现原型和模型两系统的主要相似准数相.
Abstract: According to the characteristics of high-speed water entry about the rotary projectile, an experiment plan satisfing Mach similarity has been put forward for hydroballistic modeling of high-speed water entry about the rotary projectile by using dynamic equations of projectile movement and similarity theory, which can achieve the equivalent of main similarity parameters between true object and its model at atmospheric environment.
