| 摘 要： | 基于势流理论,提出了一种求解桨舵系统非定常水动力性能的方法.系统地研究了流场中含2个升力体的面元法理论,建立了相应的数值计算模型.模型中螺旋桨和舵同时求解,二者间的相互干扰通过时域内影响系数的变化进行考虑.以定常计算结果作为非定常计算的初始值,考虑了非定常求解时泄出涡的时间效应.计算了均匀流及非均匀流中桨舵系统非定常水...

| Abstract: | Based on the potential theory,a new method to predict the unsteady performance of propeller-rudder systems was developed.Panel method including two lifting bodies in flow field was derived,and the numerical solution was also given.Propeller and rudder were solved,and the interactions between them were considered by the influence coefficients in time domain.The results of steady calculation were taken as initial values of unsteady calculation.The time effects of leak vortex were also considered in unsteady c... |
