摘要
研究了全方向推进器定常水动力性能的升力面预报方法，基于螺旋桨升力面理论建立了全方向推进器的定常水动力性能计算的数学模型，利用有限基本解法对全方向推进器的定常水动力性能进行了数值预报计算结果同日本水池模型试验结果、升力线方法计算结果对比表明。
The method for predicting the steady hydrodynamic characteristics of variable vector propeller by lifting-surface theory is studied in this paper.The mathematical models for evaluation are established based on lifting-surface theory,then the finite basis solution method is employed to predict the hydrodynamic characteristics numerically.Comparisons are made among the experimental data by Naotica NANBA,the results of the evaluation based on lifting-line theory and the results with the presented method in this paper,which show satisfactory agreement between the first and the last.
