The invention relates to an underwater vehicle with a surface active microbubble drag reduction system, the underwater vehicle has a double-layer shell, the inner-layer shell is a structural layer homogeneous shell, the outer-layer shell is a porous shell with a dense porous breathable structure, a middle pressure layer is formed between the inner-layer shell and the porous shell, and the surface active microbubble drag reduction system is arranged between the middle pressure layer and the porous shell. Densely attached microbubbles can be generated on the surface of the porous shell, and the microbubbles have the effect of reducing resistance in the running process of the underwater vehicle. The microbubbles are directly generated without depending on the head of the underwater vehicle, head noise in the sailing process can be reduced, reliable and stable work of head sonar is guaranteed while resistance is reduced, and the combat effectiveness of the underwater vehicle is improved.

    本发明涉及一种具有表面主动微泡减阻系统的水下航行器,所述水下航行器具有双层壳体,内层壳体为结构层均质壳体,外层为具有密集多孔透气结构的多孔外壳,内层壳体和多孔外壳之间形成中间压力层,多孔外壳表面能够产生密集附着的微泡,该微泡能够在该水下航行器行驶过程中减阻的功效。该微泡的产生不依赖于水下航行器头部直接产生,可降低航行过程中的头部噪声,降低阻力的同时保证头部声纳可靠稳定工作,提高水下航行器作战效能。
