    Abstract
  • 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.
