摘要
本文采用奇点分布的方法,选择了收缩卷曲的尾涡模型,通过迭代计算确定螺旋桨尾涡几何参数,并进行定常和非定常性能预估。结果表明,采用迭代方法确定尾涡几何参数、进行螺旋桨性能预估是可行的,其计算精度较经验方法也有所提高。
In terms or distribution of singularicst, Ihis paper applies iteration to the determination of after vortex geometric parameters. Estimations are carried out for the sleady and unsteady performace of the propeller. The results obtained in the paper tells the feasibility of using this method which proves to be much more precise than the method by experiencc.
