| 摘 要： | 基于螺旋桨水动力性能的升力面理论预报程序,利用iSIGHT软件进行指定负荷分布形式下桨叶螺距及拱度的优化设计研究,并对设计结果进行粘流CFD计算验证。以某集装箱船螺旋桨为母型桨,保持其原有的径向负荷分布形式,指定不同的弦向负荷分布形式,采用上述方法进行螺距及拱度的优化设计(桨叶其它参数与母型桨相同)。CFD计算表明,通过指定适当的负荷弦向分布,可以在保证效率的同时使桨叶表面压力分布更加均匀,从而推迟桨叶空化。

| Abstract: | In this paper,optimization of the pitch and camber distributions for a marine propeller is studied using a lifting-surface code for blade loading prediction integrated with the software iSIGHT.CFD simulations are conducted to verify the designs.Taking a container ship propeller as the prototype and keeping its radial loading distribution and all other geometrical parameters unchanged,the pitch and camber distributions are re-designed by specifying different chordwise loading distributions from the prototype... |
