| 摘 要： | 介绍了用船模拖曳试验来确定某喷水推进双体船平移运动水动力特性的方法,并对试验结果进行了分析.通过船模试验发现,船体平移时的水动力大小随航速增加而快速增加,在同一航速但不同尾斜角下水动力大小也各不相同;水动力的方向和水动力作用点的位置随航速的改变而改变,但变化幅度不大,受尾斜角影响较大.准确掌握船体平移运动水动力特性,可为合理制定喷水推进器的控制策略,充分发挥喷水推进船优异的机动性、操纵性提供理论依据.

| Abstract: | A method for ascertaining the hydrodynamic characteristics of waterjet driven catamaran in sideway movement by model towing experiment is described in this paper.By analyzing the experimental data,it can be found that the hydrodynamic force of the vessel moving transversally increases rapidly with the velocity,and varies at different bevel angle from stern.The direction and point of action of the hydrodynamic force have a close correlation with the bevel angle from stern, and a little with the vessel velocity.Acquiring the hydrodynamic characteristics of ship in sideway movement well and truly is of benefit to constituting reasonable control strategy of inboard waterjets and making full use of the outstanding maneuverability of waterjet propelled vessels. |
