The invention provides a wide flat bulbous bow, the width of the bulbous bow is larger than the height, the bulbous bow is provided with a side face and a bottom face, on any cross section passing through the bulbous bow, the side face and the cross section intersect at a first curve, and the bottom face and the cross section intersect at a second curve. The curvature of the first curve is larger than that of the second curve. The wide flat bulbous bow disclosed by the invention not only improves wave-making resistance generated when a ship sails, but also increases the specific gravity of drainage volume distributed at the bow part, improves the stability and seakeeping of the ship, is beneficial to resisting heaving phenomenon under the action of stormy waves, and provides stable working conditions for precision equipment and instruments. And the phenomenon that the ship touches the bottom is avoided when the ship works in a 4m extremely shallow sea area under the wave condition.
本发明提供一种宽扁平球鼻艏,所述球鼻艏的宽度大于高度,所述球鼻艏具有侧面和底面,在任意经过所述球鼻艏的横剖面上,所述侧面与所述横剖面相交于第一曲线,所述底面与所述横剖面相交于第二曲线,所述第一曲线的曲率大于所述第二曲线的曲率。本发明公开的一种宽扁平球鼻艏,不仅改善船舶航行时的产生的兴波阻力,同时增加分布在艏部的排水体积的比重,提高船舶的稳定性和耐波性,有利于抵抗风浪作用下的垂荡现象,为精密设备仪器提供稳定的工作条件,且保证了在波浪条件下的4m极浅水海域进行作业时船舶不发生触底现象。
