The invention discloses a high-submergence-depth underwater vehicle based on liquid jet and supercavity coupling resistance reduction and a driving method of the high-submergence-depth underwater vehicle. 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 better benefits are obtained. In addition, a method of combining liquid jet with the cavitator is used as a supercavitation generation method, so that the endurance time of the aircraft is further prolonged, and the deep sea navigation capability of the aircraft is further improved.

    本发明公开了一种基于液体射流与超空泡耦合减阻的大潜深水下航行器及其驱动方法。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,获得了较好的效益。此外将液体射流与空化器结合的方法作为超空泡产生方法,进一步提高了航行器的续航时间和深海航行能力。
