| 摘 要： | 文中首先建立了风帆助航船的数学模型,计算和分析了帆对船在风中的风速限界线和可自由操纵区的影响,利用最优控制理论推导出使船在风中回转战术直径为最小的操帆规律的近似公式。然后对风帆助航船在风中的回转性能进行了数值计算,研究了帆的位置对船舶操纵性的影响。结果表明,风帆助航船若帆的位置布置得当,且适当地操帆,则其在风中的船舶操纵性能比未装帆时要好得多。

| Abstract: | A mathematical model suitable for sail asisted ship is formulated. The effect of sail on control boundary and freely manoeuvrable range of the ship in wing is calculated and analysed. An approximate formula of controling sail for minimizing the tactical diameter of the ship turning in wind is derived by using the theory of optimal control. Turning ability of ship in wind is calculated. All these investigations indicate that the manoeuvrability of the ship with a sail in wind is better than that without one if the attack angle of the sail is appropriately adjusted and the position of thesail is properly arranged. |
