超空泡鱼雷外形优化

为了优化超空泡鱼雷的外形参数，获得同一空化数下的最大航行体体积，基于经验公式，考虑到空泡与超空泡雷体的关系，通过对圆盘空化器产生的超空泡形态近似处理和对超空泡鱼雷外形分段分析，推导了航行体最优外形下的半径计算公式.计算了一定空化数下航行体优化后的体积，与已有的某超空泡航行体原型做了对比，验证了优化结果的有效性.结果表明，外形优化能够增加航行体的容积和航程，提高超空泡鱼雷的性能.这为提高超空泡鱼雷的航程提供了一个方向，对今后超空泡航行体外形的优化设计提供参考.

Shape optimization of supercavitating torpedo

In order to optimize supercavitating torpedo shape and get the maximum vehicle volume under the same cavitation number, the formula for the best radius of the vehicle under the optimizing shape was deduced based on the empirical formula, by simplifying the cavity shape of disk cavitator and analyzing the vehicle shape in segmentation, considering the relationship of the cavity and the supercavitating torpedo. The volume of the optimized vehicle under a certain cavitation number was calculated, and compared with an existing vehicle model. It verified the effectiveness of the result. The results show that, shape optimization could increase the volume and the voyage, and improve the performance of the supercavitating torpedo. It provides a direction for increasing voyage of the supercavitating torpedo, and could be a reference for future shape design of supercavitating vehicle.
