【摘要】 针对某30mm 带尾翼高速航行体,开展了其水下高速航行(初速 v0>500m/s) 的水动力布局结构设计。设计了带尾翼高速航行体的空化器结构参数,基于 FLUENT 6.2 计算软件开展了带尾翼高速航行体的超空泡形态特性分析;在超空泡形态下,计算了不同攻角下带尾翼航行体的水动阻力、升力、稳定力矩等水动力参数;研究了带尾翼高速航行体的航行稳定性,给出了航行体的摆动攻角曲线。研究结果为开展带尾翼航行体的超空泡水下试验提供了理论参考。
【Abstract】 Structure design of hydrodynamic distribution has been conducted for a 30mm high-speed body with fin at an initial velocity of 500m/s.Several structure parameters of the cavitator on the body have designed,and their supercavitation profiles have been analyzed with the application of commercial code FLUENT 6.2.The hydrodynamic parameters such as hydrodynamic drag,lift, stable moment of the body have been calculated under various attack angles under the supercavitation condition.Moreover,the shipping stability of these bodies has been investigated,and their oscillation attack angle curves have been presented.Our results can provide guides for further experimental investigation about hydrodynamic characteristic of supercavitating flow around the underwater high-speed body with fin mounted.
