水下垂直发射航行体空泡流动研究

水下垂直发射航行体是工程研制的重要对象之一,水下垂直发射技术是航行体研究的核心与关键。动基座发射与跨介质飞行是水下垂直发射的两个突出特点,特别是在一定条件下出现的空泡现象使得水下垂直发射物理现象异常复杂。鉴于此,系统梳理了水下垂直发射需要关注的问题,介绍了水下垂直发射航行体空泡流研究的主要技术途径和研究手段,探讨了未来的主要发展趋势。

Research on Cavitating Flow Round an Underwater Vertical Launch Vehicle

Underwater vertical launch vehicle is one of the important objects of engineering development, which is highly related to the key technology of vertical launching. The prominent features of underwater vertical launch is the launch with moving base and the flight across different fluid media, and especially when cavitation occurs,it becomes more complicated. In view of this, the main concerns of underwater vehicle launch have been proposed in this paper, and the main technical approaches and research methods for the cavitation flow around an underwater vertical launch vehicle have been summarized. Moreover, the main trend of technology development has also been discussed.
