Air injection structure of air layer resistance reduction device, ship air layer resistance reduction system and air layer resistance reduction ship

The invention discloses an air injection structure of an air layer resistance reduction device, a ship air layer resistance reduction system and an air layer resistance reduction ship. The air injection structure of the air layer resistance reduction device comprises a pressure stabilizing cavity and a plurality of spray holes formed in a ship bottom plate, a pressure stabilizing pipe is arranged above a longitudinal bone, an inner cavity of the pressure stabilizing pipe is the pressure stabilizing cavity, the pressure stabilizing pipe is provided with a plurality of air conveying pipes in one-to-one correspondence with the spray holes, and the two ends of each air conveying pipe communicate with the pressure stabilizing pipe and the corresponding spray hole correspondingly. In the prior art, the pressure stabilizing cavity is directly connected with the ship bottom plate, so that the pressure stabilizing cavity can penetrate through the longitudinal bone, and a longitudinal bone reinforcing plate needs to be
