A bladeless sail is characterized in that a spraying device is fixed on a main deck through a base, the spraying device is provided with an annular main body, the annular main body comprises an inner shell and an outer shell, and the inner shell and the outer shell are connected through a connecting plate to form a hollow inner cavity. The base is provided with a honeycomb-shaped base wall, a centrifugal pump is fixed to the center in the base, a silencing cavity is formed above the centrifugal pump and fixed to the top of the base, and a drainage hole is formed in the top of the center of the silencing cavity and communicated with an air inlet in the bottom of the spraying device. Air is driven by an impeller of the centrifugal pump to enter the base through the honeycomb-shaped base wall, is pressurized by 15-20 times in a cyclone mode, is pushed to the drainage pipe on the top, enters the hollow inner cavity through the air inlet and is exhausted from the air outlet and the top air outlet. The area of the original sail blade can be greatly reduced, the maintenance workload of the sail blade can be effectively reduced, the weight can be reduced, the oil consumption can be reduced, the wind energy is improved by 15-20 times compared with the wind power of the original sail, and the boosting power is improved.
一种无叶风帆,喷射装置通过基座固定在主甲板上,喷射装置带有环形主体,环形主体包括内壳体与外壳体,内壳体与外壳体通过连接板连接形成中空内腔。基座带有蜂窝状基座壁,基座内部中心固定有离心泵,离心泵上方设置有消音空腔,消音空腔固定在基座顶部,消音空腔中心顶部设置有引流孔,引流孔与喷射装置底部的进风口连通。空气在离心泵的叶轮带动下,经蜂窝状基座壁进入基座内,并气旋加压至15~20倍,推至顶部的引流管,经过进风口进入中空内腔内,从出风口、顶部出风口排出。本发明可使原有帆叶面积大量减少,可有效降低风帆帆叶维修保养工作量,减轻重量可降油耗,使风能比原风帆风力提升15‑20倍,提高助推功率。
