| 摘 要： | 修改压力分布设计螺旋桨新型叶剖面来改进空化斗的工作已经进行多年,但是均基于薄翼理论进行二维剖面与三维叶剖面之间的转换。文中分别用B样条曲线和曲面表达二维剖面和三维桨叶,指定Eppler剖面的压力分布作为三维目标压力;将一个初始螺旋桨用B样条曲线表达其0.8R处的剖面几何;建立算法调整0.8R剖面对应的B样条控制多边形,进而调整桨叶几何,使得0.8R处三维面元法预报压力逼近目标压力。文中最后还讨论了高负荷时该剖面的压力分布情况。

| Abstract: | The B-spline curve and B-spline surface are employed to define 2D wing section and 3D pro-peller blade geomertry respectively.The pressure distribution of Eppler section is considered as the target for designing blade section at 3D condition.Finally,The method and the example to design 0.8R blade section to meet pressure distribution same as that of Eppler section are presented. |
