Ship surface micro-hole jet flow drag reduction structure

The invention provides a ship surface micro-hole jet flow drag reduction structure. The ship surface micro-hole jet flow drag reduction structure comprises diversion grooves (3) which are formed below a ship waterline, wherein a multi-hole shell plate (5) is covered on the diversion grooves (3) in the side face of a ship, a ship stem screen plate (6) is covered on the diversion grooves (3) in the front portion of the ship, the size of the cross sections of the diversion grooves (3) extending to the ship tail portion is gradually decreased and a water discharge hole (2) is formed. Micro-hole jet flow is formed on the wall face below the ship waterline, is utilized to change a border layer flow field so as to reach the purpose of reducing resistance of ship navigation. When the structure is manufactured and installed, a traditional ship building method is not changed, machining is easy, and engineering practice is convenient.
