The device for reducing the frictional resistance of the ship body is provided with an automatic air distribution device (20) for automatically distributing air by switching the blowing of air from the plurality of air blowing ports to the bottom of the ship at the plurality of air blowing ports. In the ship body frictional resistance reducing device, n air outlets having a predetermined width are arranged by dividing in the width direction of the ship body in n according to the width of the bottom of the ship, and an automatic air distribution device (20) switches among the plurality of air outlets from which air is blown in a specified order. Air is blown out from all of the plurality of air outlets in one of the air blow-out cycles. As a result, it is possible to increase the frictional resistance reduction effect due to air lubrication while suppressing the power for air blowing using periodic blowing.
船体摩擦阻力降低装置具备自动空气分配装置(20),该自动空气分配装置使来自多个空气吹出口的空气吹出在多个空气吹出口中切换并且流向船底,自动地分配空气,船体摩擦阻力降低装置将具有规定的宽度的n个空气吹出口根据船底的宽度在船体宽度方向上n分割而配置,自动空气分配装置(20)以确定好的顺序切换多个空气吹出口中的吹出空气的空气吹出口,并且在空气吹出周期的1个周期中从全部的多个空气吹出口吹出空气。由此,能够利用周期吹出,抑制用于空气吹出的动力,并且增大空气润滑所带来的摩擦阻力降低效果。
