桨毂是各个桨叶安装结合的部位，位于螺旋桨末端，多为圆锥或圆台形，和艉轴互相贴合，贴后面处开一键槽，镶以键，是艉轴带动螺旋桨旋转。
The surface of propeller, hub and the vortex of blade is discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution.
桨叶、桨毂表面和螺旋桨尾涡面采用四边形双曲面元离散，以消除面元间的间隙。 由于导管的存在，螺旋桨尾涡面模型没有收缩，采用等半径向下游溢出。
