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 additionally arranged on the longitudinal bone in order to compensate for the influence of opening holes in the longitudinal bone on the overall strength of the ship. According to the embodiment, the pressure stabilizing cavity is formed above the longitudinal bone, the longitudinal bone does not need to be cut or penetrate through, and the structural strength of the ship cannot be affected.

本发明公开了气层减阻装置喷气结构、船舶气层减阻系统及气层减阻船，其中，气层减阻装置喷气结构包括稳压腔和设于船底板上的若干喷孔，稳压管设于纵骨的上方，稳压管的内腔为稳压腔，稳压管上设有若干与喷孔一一对应的输气管，输气管的两端分别连通稳压管和对应的喷孔。现有技术中稳压腔直接与船底板连接，因此会贯穿纵骨，为弥补在纵骨上开孔对船舶总体强度的影响，需要在纵骨上增加纵骨补板。而本实施例，稳压腔设置纵骨的上方，不需要切割和贯穿纵骨，不会对船舶结构强度产生影响。
