The invention belongs to the field of underwater naval vessels, and particularly relates to an underwater unmanned vehicle. In order to enable the underwater unmanned vehicle to sail at a high speed and have good self-stability, the invention discloses the underwater unmanned vehicle. The underwater unmanned vehicle comprises a front cabin section, a steering section and a rear cabin section, the steering section comprises a front connecting piece and a rear connecting piece, the front connecting piece and the rear connecting piece are provided with a front through hole and a rear through hole respectively, the front cabin section is provided with at least two jet flow nozzles, a cavitation generator is arranged in the rear cabin section and connected with an air guide pipeline, and the air guide pipeline is connected with the jet flow nozzles. The front end of the gas guide pipeline is connected with the jet flow nozzles, so that when the cavitation generator is started, high-pressure gas in the cavitation generator is sprayed out from all the jet flow nozzles to form supercavitation bubbles, and the maximum navigational speed of the unmanned underwater vehicle is increased. By postposition of the cavitation generator, the distance between the center of mass and the center of buoyancy can be increased, so that the self-stability of the underwater unmanned vehicle during underwater navigation is improved.

    本发明属于水下舰艇领域,特别是涉及一种水下无人航行器。为了使水下无人航行器能够高速航行,且具有良好的自稳性,本发明公开了一种水下无人航行器。水下无人航行器包括前部舱段、转向段和后部舱段,转向段包括前连接件和后连接件,前、后连接件上分别设有前、后穿孔,前部舱段上设有至少两个射流喷口,后部舱段内设有空化发生器,空化发生器上连接有导气管路,导气管路的前端与射流喷口连接,以在空化发生器开启时使空化发生器内的高压气体从所有射流喷口喷出而形成超空泡,从而提升水下无人航行器的最大航速。通过将空化发生器后置,能够增大质心与浮心之间的距离,从而提升水下无人航行器水下航行时的自稳性。
