The invention belongs to the technical field of marine gas layer resistance reduction, and discloses a gas layer resistance reduction ship which comprises a ship body, a gas layer resistance reduction device and a gas dredging device, the gas layer resistance reduction device is used for forming a resistance reduction gas layer on the bottom face of the ship body, and a gas dredging opening is formed in the end, close to a stern, of the bottom face of the ship body; the gas dredging device comprises a gas dredging cavity and an exhaust channel, and the gas dredging cavity is formed in the ship body and communicates with the gas dredging opening; one end of the exhaust channel is communicated with the air dredging cavity, and the other end of the exhaust channel penetrates through a deck of the ship body. The gas dredging device drains overflowing gas of the drag reduction gas layer at the stern end of the ship body, so that the part of overflowing gas passes through the gas dredging opening, the gas dredging cavity and the exhaust channel and then is guided to the deck to be exhausted, and the situation that the overflowing gas enters a propeller area to affect the performance of the propeller is avoided; therefore, the energy-saving and resistance-reducing effects of the air layer resistance-reducing device are integrally improved. The air dredging cavity and the exhaust channel are both arranged in the ship body, and resistance borne by the ship body in the sailing process cannot be increased.
本发明属于船用气层减阻技术领域,公开了一种气层减阻船舶,包括船体、气层减阻装置和气体疏通装置,气层减阻装置用于在船体的底面形成减阻气层,船体的底面靠近船艉的一端设置有疏气口;气体疏通装置包括疏气腔和排气通道,疏气腔设置于船体内,疏气腔与疏气口连通;排气通道设置于船体内,排气通道的一端与疏气腔连通,另一端穿过船体的甲板。气体疏通装置将减阻气层在船体的船艉端的溢流气体进行引流,使该部分溢流气体通过疏气口、疏气腔和排气通道后,导流至甲板上排出,避免溢流气体进入到螺旋桨区域而对螺旋桨性能产生影响,从而整体增加气层减阻装置的节能减阻效果。疏气腔以及排气通道均设置在船体内,不会增加船体航行时受到的阻力。
