细长体空泡流型试验研究

在水洞中对细长体通气附体空泡流型和控制途径进行了系列模型实验研究；获得了细长体通气附体空泡五种对称基本空泡流型与三种非对称基本空泡流型；在此基础上，从水下超空化超高速自主航行体的需求出发，提出了三种可用的空泡流型：非对称双空泡流型、尾部开式穿透非对称空泡流型和尾部半开式非对称空泡流型。并分析讨论了这三种空泡流型下航行体的重力平衡、运动控制与稳定性问题。同时，通过对有关参数的设计与控制，在水洞模型试验中实现了水下超空化超高速自主航行体的这三种空泡流型。

Experimental investigation on cavity flow pattern of slender bodies

A series of experimental investigation on ventilated cavity flow pattern of slender bodies and their control methods are carried out in the high-speed water tunnel. Five kinds of stable symmetic basic cavity flow patterns and three kinds of asymmetric ones are formed in experiments. Based on dynamical analysis,three kinds of feasible stable cavity flow patterns for high-speed supercavitating underwater vehicle are presented . They are asymmetric double-cavity flow pattern, asymmetric piercing supercavity flow pattern opened at the end of the vehicle and asymmetric supercavity flow pattern half-opened at the end of the body.And these three kinds of cavity flow patterns are achieved by controlling experimental parameters.
