【摘要】 螺旋桨在波浪中随船运动是前进、旋转和振荡三者的结合。本文近似计算波浪中桨流体动力性能相对于静水中性能的变化，将波浪中螺旋桨运动分解为旋转兴波和振荡兴波两部分线性迭加。利用Ｇｒｅｅｎ函数法，求解其兴波问题，给出桨推力的变化值。编制程序进行了系列数值计算。结果表明，波浪中螺旋桨推力系数变化值随桨轴浸深、桨升沉振荡频率和幅值而变化。更多还原

【Abstract】 To calculate open water characteristics of a propeller in waves, the problem is considered as two separated ones: one is the wave-making of propeller oscillation, the other is the wave-making of propeller rotation. The two problems are solved using Green function method. A computer program is developed according to the present method, and a series of numerical calculations are made with the program. The result shows: the propeller thrust depends on the submergence, the frequency and amplitude of propeller oscillation.更多还原
