摘要
在拖曳水池中进行了自航约束模舵力测量试验,对扭曲舵和普通舵的舵力进行了测量,比较分析了扭曲舵和普通舵的舵力特性。试验结果表明,在0°舵角时,扭曲舵上的受力状态得到明显改善,对舰船的直航性和舵机受力是有利的。在通过打舵使舰船发生回转时,扭曲舵不仅能使舵轴上的受力状态得到改善,而且能够提高舵的操纵力,改善舰船的回转性能。
In order to study on hydrodynamic performance of twisted rudder, a self-propulsion test of twisted rudder is done in the towing tank. The three-component forces of twisted rudder and ordinary rudder are measured and compared with each other. The results show that transverse force on the twisted rudder is much smaller than the ordinary rudder at 0°rudder angle. It is favorable for rudder force state. The transverse force on the twisted rudder is larger than the ordinary rudder at 10° rudder angle. And the twisted rudder can improve the maneuverability of ship.
