The invention discloses a ship auxiliary propulsion and resistance reduction system, and particularly relates to the field of energy conservation and carbon reduction in the shipping industry, the ship auxiliary propulsion and resistance reduction system comprises a suction sail body, the inner wall of the suction sail body is fixedly connected with a suction sail main mast structure, the bottom of the suction sail main mast structure is fixedly connected with a suction sail base, and the suction sail base is fixedly connected with a suction sail main mast. A ship body is fixedly connected to the bottom of the suction sail base, an air suction pipe system is connected to the bottom of the suction sail base, and the suction sail body can form large auxiliary thrust under the condition that the wind direction is proper and can be unfolded through a mechanical structure under the condition that the ship is against the wind. Therefore, a streamline structure capable of reducing air resistance above a ship waterline is formed at the head of the ship, wind opposite to the ship is guided to the two sides of the ship, a shielding effect is formed on cargoes above a deck surface, resistance generated by a streamline windward side relative to containers or irregular cargoes on the deck surface under the headwind condition is smaller, and therefore the ship is protected against wind. And therefore, the air resistance of the ship can be reduced under the headwind condition.
本发明公开了一种船舶辅助推进及减阻系统,具体涉及航运业节能减碳领域,包括吸力帆帆体,所述吸力帆帆体的内壁固定连接有吸力帆主桅结构,所述吸力帆主桅结构,所述吸力帆主桅结构的底部固定连接有吸力帆底座,所述吸力帆底座的底部固定连接有船体,所述吸力帆底座的底部连接有空气吸入管系,吸力帆帆体在风向合适条件下可以形成较大辅助推力,在船舶逆风条件下时可以通过机械结构展开,从而在船舶首部形成一种可减少船舶水线以上空气阻力的流线型结构,将与船舶逆向的风导向船舶两侧,对位于甲板面以上的货物形成遮蔽效应,逆风条件下流线型的迎风面相对甲板面上的集装箱或是不规则货物产生的阻力更小,从而在逆风情况下也可减小船舶空气阻力。
