摘　　要：本文用船体、螺旋桨、舵“组合型”数学模型,对一艘驱逐舰船模的操纵性进行了预报。船体的水动力导数和船体、螺旋桨、舵相互之间的流体动力干扰是用船模斜拖试验和旋臂试验确定的。预报采用进退、横漂、首摇和横摇四个自由度的方程,考虑了横摇对水平面运动的耦合影响。计算结果与自航船模试验结果进行了比较。符合情况良好。The maneuverability of a destroyer is predicted on the basis of'combined model' of hull, propeller and rudder. The hydrodynamic coefficients of hull and the hydrodynamie interaction coefficients between hull, propeller and rudder are obtained by ship model oblique towing test and rotating arm test. The mathematic model has four degrees of freedom (surge, sway. yaw and roll), taking the couple motion of roll on horizontal plane motion into account. The calculation results are compared with those obtained from self-propulsion modet and they agree quite well.
