2.
Since the fin size keeping the longitudinal motion stability of SWATH could not be set directly,starting with the restrictions to the size of span and chord of the real ship fins,the variation range of the fin size in the speed range of 40 knot is presented in this paper,then in the range the fin size satisfying certain motion performance at the different speed further is determined.
针对保持SWATH船纵向运动稳定鳍的结构尺寸难以确定的特点,从实船对鳍的展长和弦长取值的约束条件出发,利用计算机仿真出SWATH船在40kn的航速范围内保持纵向运动稳定的鳍结构尺寸的变化范围,然后,从这一范围内确定出不同航速且具有一定运动性能要求的鳍尺寸变化范围。
