The invention discloses a gas-electric coupling driving underwater vehicle based on supercavitation resistance reduction. The power system for doing work through expansion of compressed gas is used for providing power for the underwater vehicle, meanwhile, waste gas of the power system generates supercavitation to reduce resistance of the vehicle, a traditional lithium battery underwater vehicle power system is replaced, the system compactness is improved by adopting the method that the power system and a resistance reduction system are coupled, and the navigation resistance is reduced. The navigational speed, the endurance time and the high-speed maneuverability of the underwater vehicle are effectively improved; and compared with a pure electric system and a pure pneumatic system, the hybrid power system is adopted under extreme working conditions, so that the high-speed cruising ability can be effectively improved, and better benefits are obtained.

    本发明公开了一种基于超空泡减阻的气电耦合驱动水下航行器。本发明利用压缩气体膨胀做功的动力系统为水下航行器提供动力,同时动力系统废气产生超空泡为航行器减阻,代替传统的锂电池水下航行器动力系统,采用动力系统与减阻系统耦合的方法增加了系统紧凑性,减小了航行阻力,有效提高了水下航行器的航速、续航时间和高速机动性;在极端工况下采用混动系统,相较于纯电动系统和纯气动系统而言可以有效提高告诉续航能力,获得了较好的效益。
