Bionic ship wing

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 rec
