The invention discloses a polymer drag reducer injection type hydrofoil, and belongs to the technical field of underwater vehicle polymer drag reduction. The drag reducer injection structure solves the problem that an existing underwater vehicle lacks a drag reducer injection structure capable of stably outputting a polymer drag reducer and being attached to the surface of a part to be subjected to drag reduction in the underwater vehicle. One end of the steady flow cavity is communicated with a solution storage tank in the underwater vehicle through a discharge channel, the cover plate is inserted in the hydrofoil body in parallel and in a sliding mode, the lower surface of the cover plate is attached to the upper surfaces of the multiple rectifying plates, and an injection channel is formed between the outer surface of one end of the cover plate and the inner wall face of one end of the steady flow cavity. The steady flow cavity has a steady flow effect on the solution, so that the stable output of the polymer solution is realized; the flow state of the fluid is adjusted through the rectifying plate, so that the polymer solution flows stably; the polymer solution flows out to the surface of the hydrofoil through the injection channel, friction resistance generated during sailing is reduced, and the effect of improving the sailing performance of the underwater vehicle is achieved.

    一种聚合物减阻剂注入式水翼,属于水下航行体聚合物减阻技术领域。本发明解决了现有的水下航行体中缺少一种能够使聚合物减阻剂稳定输出且能够贴合水下航行体中待减阻部位表面的减阻剂注入结构的问题。稳流腔体的一端通过排放通道与水下航行器内的溶液储存箱连通,盖板平行且滑动插装在水翼主体上,盖板的下表面与若干整流板的上表面贴合,盖板的一端外表面与稳流腔体的一端内壁面之间形成注入通道。稳流腔体对溶液具有稳流作用,从而实现对聚合物溶液的稳定输出;通过整流板调整流体行态,使聚合物溶液流动稳定;聚合物溶液通过注入通道流出至水翼表面,减小航行时产生的摩擦阻力,达到改善水下航行器航行性能的效果。
