The embodiment of the invention provides a stealth system for inhibiting cavitation bubble wake flow of an underwater vehicle through active jet flow. The stealth system comprises a water tank I, a water conveying pipeline I, a control unit I, a jet flow cavity I, a bait throwing unit, a control unit III, a water tank II, a water conveying pipeline II, a control unit II and a jet flow cavity II. The two ends of the water conveying pipeline I are connected with the water cabin I and the jet flow cavity I respectively; the two ends of the water conveying pipeline II are connected with the water tank II and the jet flow cavity II respectively; the jet flow cavity I is arranged in an upper layer building of the underwater vehicle, and the jet flow cavity II is arranged in four rudder blades of a tail rudder of the underwater vehicle; the bait throwing unit is arranged in the middle of the broadside of the underwater vehicle, and each of the control unit I, the control unit II and the control unit III comprises a controller and a control signal transmission cable; according to the technical scheme, flow field noise can be reduced, flow in a boundary layer can be stabilized, cavitation of the surface of an appendage can be inhibited, and bubble wake flow can be effectively interfered.

    本发明实施例提供一种主动射流抑制水下航行器空化气泡尾流的隐身系统,包括:水舱Ⅰ、输水管路Ⅰ、控制单元Ⅰ、射流腔体Ⅰ、诱饵投放单元、控制单元Ⅲ、水舱Ⅱ、输水管路Ⅱ、控制单元Ⅱ和射流腔体Ⅱ;输水管路Ⅰ的两端分别与水舱Ⅰ和射流腔体Ⅰ相连接;输水管路Ⅱ的两端分别与水舱Ⅱ和射流腔体Ⅱ相连接;射流腔体Ⅰ设置于水下航行器上层建筑的内部、射流腔体Ⅱ相同布置在水下航行器尾舵的四片舵叶中;诱饵投放单元,设置于所述水下航行器舷侧的中部位置,述控制单元Ⅰ、控制单元Ⅱ、控制单元Ⅲ分别包括:控制器和控制信号传输电缆;本发明技术方案,能够降低流场噪声,稳定边界层内的流动,抑制附体表面的空化,对气泡尾流产生有效干扰。
