The invention provides a bionic ship wing which is connected with the tail of a ship and comprises a horizontal wing and a vertical wing. Wherein the horizontal wing is arranged below a waterline, one end of the vertical wing is connected with the horizontal wing, and the other end is fixed with the tail of a ship. The horizontal wing is provided with a tooth-shaped front edge, a tooth-shaped tail edge and a ridge-shaped structure. The bionic ship wings are connected with the tail of the ship, boundary layer fluid separation is prevented through the tooth-shaped front edge, the tooth-shaped tail edge and the ridge-shaped structure, the lift-drag ratio of a horizontal wing is increased, the adjusting capacity of the ship wings to a wake flow field and the wake flow energy recovery capacity are further improved, and the energy-saving and resistance-reducing effects of ship wing appendages are enhanced. And the tooth-shaped front edge, the tooth-shaped tail edge and the ridge-shaped structure can be used for rectification, the turbulence intensity of the tail part is reduced, and the flow noise is further reduced.
本发明提供一种仿生船翼,仿生船翼与船舶尾部连接,包括水平翼和垂直翼。其中,水平翼设置在水线以下,垂直翼一端与水平翼连接,另一端与船舶尾部固定。水平翼设置有齿状前缘、齿状尾缘和脊状结构。仿生船翼与船舶尾部连接,通过齿状前缘、齿状尾缘和脊状结构,阻止附面层流体分离,提高水平翼升阻比,进一步提升船翼对尾流场的调节能力和尾流能量回收能力,增强船翼附体节能减阻效果;齿状前缘、齿状尾缘、脊状结构可进行整流,降低尾部湍流强度,进一步降低流噪声。
