The invention discloses a hyperbolic reverse-arch ship bottom structure of a high-speed drainage type ship. The structure comprises a prow, a ship board, a stern and a ship bottom, the bottom surface of the prow is an upslope-shaped inclined cambered surface, the bottom of the stern is an upwarp inclined cambered surface, a bilge keel is arranged at the ship bottom, the middle part of the ship bottom is arched upwards to form an arc shape under the matching of the bilge keel, and a power device is mounted at the stern. Compared with the prior art, the structure has the advantages that fluid passes through and impacts the arched middle rear part of the ship bottom to generate an impact force for lifting the ship bottom, and the impact force indirectly lowers the head of the ship while lifting the tail of the ship, so that the ship is approximately in a longitudinal horizontal state; when the ship is low in speed, a small amount of air rushing from the bow is gathered at the arched junction of the longitudinal and transverse positions of the ship bottom, and a cavity is formed, so that the viscous resistance can be effectively reduced.
本发明公开了一种高速排水型船舶双曲反弓船底结构,包括船头、船舷、船尾和船底,所述的船头底面为上坡状的斜弧面,所述的船尾底部为上翘的斜弧面,所述的船底设有舭龙骨,船底在舭龙骨的配合下在中部向上拱起形成弧形,所述船尾处安装有动力装置。本发明与现有技术相比的优点在于:流体经过并冲击船底拱起中后部,产生一个将船底抬升的冲击力,这个冲击力在将船舶尾部抬升的同时,间接的压低船舶头部,使船舶大致处于纵向水平状态,另外,船在慢速时,船底的纵向和横向处的拱起交汇处聚集从船头少量涌入的空气,并形成一个空腔,能有效减少粘性阻力。
