The invention relates to the technical field of ship sailing resistance reduction, in particular to a ship bubble resistance reduction system which is composed of a high-pressure gas generating device, a gas conveying pipeline and a bubble generating device. The M bubble generating devices are evenly distributed and fixed to a ship bottom plate. The gas conveying pipeline is composed of M first-stage gas conveying pipes which are communicated with the high-pressure gas generating device and the bubble generating device at the same time. The bubble generation device comprises a body, a transition communication pipeline unit, a direct communication pipeline unit and N aeration assemblies. N first-stage water body flow channels and a second-stage water body flow channel are formed in the body. And each aeration assembly conveys high-pressure gas through a high-pressure gas generation device and supplies the high-pressure gas into the first-stage water body flow channel. For a single bubble generating device, in the sailing state of a ship, a water body quickly penetrates through the first-stage water body flow channels, and high-pressure gas sequentially passes through the first-stage gas conveying pipe, the transition communicating pipeline unit, the direct communicating pipeline unit and the aeration assembly and is continuously released into the first-stage water body flow channels so as to generate a gas-water mixture.

    本发明涉及船舶航行减阻技术领域,尤其是一种船舶气泡减阻系统,其由高压气体发生装置、输气管线和气泡发生装置构成。M个气泡发生装置均布、且固定于船底板。输气管线由M条同时连通高压气体发生装置和气泡发生装置的一级输气管构成。气泡发生装置包括本体、过渡连通管路单元、直接连通管路单元以及N个曝气组件。在本体的内部开设有N条一级水体流道和一条二级水体流道。各曝气组件由高压气体发生装置输送高压气体,且供入一级水体流道。就单个气泡发生装置而言,在船舶航行状态下,水体快速地贯通一级水体流道,高压气体依序经由一级输气管、过渡连通管路单元、直接连通管路单元、曝气组件而持续地向着各一级水体流道中进行释放,以生成气水混合体。
