The invention provides a novel supercavitation airfoil profile hydrofoil craft which comprises a ship main body, a front hydrofoil arranged at the front section of the ship main body and a tail hydrofoil arranged at the stern, and the front hydrofoil comprises a flat wing, a novel supercavitation wing type inclined wing and a folding wing which are connected in sequence; the tail hydrofoil comprises a vertically-installed NACA wing type vertical wing and a novel super-cavitation wing type short wing horizontally fixed to the lower end of the vertical wing. The novel supercavitation airfoil comprises a suction surface and a stress surface of which one ends are connected and the other ends are opened, and a contraction end connected with the opening end, and the suction surface, the stress surface and the contraction are respectively used for determining the outline by utilizing a numerical simulation method, a Johnson three-order design method and an NACA design method. According to thehydrofoil craft, the pneumatic-hydrodynamic integrated combined front hydrofoil with the novel super-cavitation airfoil and the deep-submerged empennage are adopted, so that the hydrofoil craft has good rapidity and stability during high-speed and low-speed sailing, and the effects of being high in working adaptability, simple in structure, reliable in working and capable of saving the manufacturing cost are achieved.

    本发明提供一种具备新型超空泡水翼的水翼船,包括船舶主体,安装在船舶主体前段的前水翼,及设置在船尾的尾水翼,前水翼包括依次连接的平翼,和新型超空泡翼型的斜翼、折翼;尾水翼包括垂直安装的NACA翼型的垂翼,以及水平固定在垂翼下端部的新型超空泡翼型的短翼;新型超空泡翼型,包括两块一端相接另一端张开的吸力面和受力面,以及与张开端连接的收缩端,吸力面、受力面和收缩分别利用数值模拟方法、约翰逊三阶设计方法和NACA设计方法确定轮廓。本发明的水翼船采用具备新型超空泡翼型的气水动一体化组合型前水翼和深浸式的尾翼,使该水翼船在高低速航行时都具有较好的快速性和稳定性,达到工作适应性强、结构简单、工作可靠、节约制造成本的效果。
