The invention discloses a retractable flat bulbous bow which comprises two symmetrical hollow watertight shells, a storage cabin at the front end of a hull, a vertical rotating shaft penetrating through the top of the storage cabin and a driving device for driving the vertical rotating shaft to rotate, and a shaft support for supporting the bottom of the vertical rotating shaft is fixedly mounted at the bottom of the storage cabin. The outer side of the top of the storage cabin is provided with a lower bearing which fixes a vertical rotating shaft and seals the vertical rotating shaft to penetrate through the edge of the top of the storage cabin, the middle of the vertical rotating shaft is connected with a connecting rod, and the other end of the connecting rod is connected with a watertight shell. The two watertight shells rotate to the front portion of the ship along the vertical rotating shaft to be attached to each other to form a flat bulbous bow with the oval horizontal section and the parabola-shaped upper side and the parabola-shaped lower side, and the flat bulbous bow rotates along the vertical rotating shaft to be separated and placed in the storage cabin. The watertight shell forms a flat bulbous bow through the vertical rotating shaft at a high speed of the ship, so that the sailing speed and stability of the ship are improved.
本发明公开一种可收放的扁球艏,包括两个对称的、内部中空的水密壳体、船体前端且底部置于水线之下的存放舱室、贯穿存放舱室顶部的垂直转轴以及驱动垂直转轴转动的驱动装置,存放舱室底部固定安装有承托垂直转轴底部的轴托,存放舱室顶部外侧设置有固定垂直转轴且密封垂直转轴穿过存放舱室顶部边缘的下轴承,垂直转轴中部连接连杆,连杆的另一端则连接水密壳体,水密壳体纵向剖面为翼型,两所述水密壳体沿垂直转轴转动至船舶前部相互贴合后形成水平剖面为椭圆形,上下两侧为高度由中间逐渐往两边降低的抛物线型的扁状球艏,沿垂直转轴转动分离置于存放舱室内。在舰船高航速下通过垂直转轴使水密壳体形成扁状球艏,以提高舰船的航行速度和稳定性。
