The invention provides a gas drag reduction ship. The gas drag reduction ship comprises a ship bottom flat plate; the at least one group of gas anti-drag air injection mechanisms are arranged at the incident flow end of the inner side of the ship bottom flat plate, the number of the gas anti-drag air injection mechanisms in each group is at least one, when the number of the gas anti-drag air injection mechanisms is one, the gas anti-drag air injection mechanisms are arranged on the middle longitudinal section line of the ship bottom flat plate, and when the number of the gas anti-drag air injection mechanisms is multiple, the gas anti-drag air injection mechanisms are arranged on the middle longitudinal section line of the ship bottom flat plate. The multiple gas resistance-reducing air injection mechanisms are symmetrically arranged relative to the middle longitudinal section line of the ship bottom flat plate, and the gas resistance-reducing air injection mechanisms inject air through the through holes in the ship bottom flat plate; each gas resistance-reducing gas injection mechanism at least corresponds to one flow guide cover, the flow guide covers are arranged in the through holes of the ship bottom flat plate and located on the outer side, a narrow slit is formed by the flow guide covers and the ship bottom flat plate, and the narrow slit is used for allowing gas to be injected out and enabling the gas to flow along the ship bottom flat plate. According to the gas resistance reduction ship, the projection of the gas resistance reduction air injection device in the ship width direction does not need to cover the whole ship width, and the whole ship width coverage of a gas layer can be achieved.
本发明提供一种气体减阻船舶,包括:船底平板;至少一组气体减阻喷气机构,设于船底平板内侧的迎流端,每组中的气体减阻喷气机构的数量至少为一个,当气体减阻喷气机构的数量为一个,气体减阻喷气机构设于船底平板的中纵剖线,当气体减阻喷气机构的数量为多个,且多个气体减阻喷气机构关于船底平板的中纵剖线对称设置,气体减阻喷气机构通过船底平板上的贯穿孔喷气;多个导流盖,每个气体减阻喷气机构至少对应一导流盖,导流盖设于船底平板的贯穿孔且位于外侧,导流盖与船底平板形成一道窄缝,窄缝用于供气体喷出并使气体沿船底平板流动。上述气体减阻船舶能够做到气体减阻喷气装置在船宽方向上的投影无需覆盖整个船宽便可以实现气层的全船宽覆盖。
