潜艇超空泡技术应用分析

摘要

Based on the current development of supercavitation technology, the necessity of supercavitation submarine is expounded. The basic principle of supercavitation technology is introduced. Based on the configuration of the supercavitation torpedo, the deformation cavitator is proposed. How to choose the propulsion of supercavitation submarine and control system are demonstrated. The function and the possible problems of stem rudder are analyzed. The stability problem of the supercavitation submarine is analyzed and the development of the supecrcavitation submarine is putted forward. The characteristics of viscous flow filed of SUBOFF model is calculated, the preconception of supercavitation submarine are putted forward. It is shown that, the wetted area are formed in the head of submarine, the front of the command room of submarine, both sides of the symmetry of the command room and the rear wing . Based on the above results, the improvement of the program is presented. Main work of submarine supercavitation in the future is discussed.%结合目前国内外超空泡技术的发展，论述发展超空泡潜艇的必要性，介绍了超空泡技术基本原理。依据超空泡鱼雷的配置，提出“变形空化器”的概念；论证超空泡潜艇推进和控制系统的选择；分析导引设备和尾舵的作用以及可能出现的问题。结合4种超空泡航行体稳定模式，分析超空泡潜艇水下稳定性问题，提出超空泡潜艇发展设想。结合对潜艇操纵研究，分析超空泡潜艇的水动力特性问题。同时，对 Suboff潜艇模型进行了流场特性的仿真计算，结果表明：潜艇的头部、指挥室的迎风面、指挥室的两侧艇体和潜艇的尾翼均存在一定的沾湿区域。基于此结果，提出相应的改进方案。对超空泡潜艇未来主要工作进行展望。
