文章以整个飞行跨度内的高效率为目标设计了某型太阳能飞机的螺旋桨,根据给定的飞行速度、螺旋桨直径、需用拉力,结合太阳能飞机的飞行高度曲线,确定了桨叶数、翼型和螺旋桨转速,计算出若干设计高度点的弦长分布、桨距角分布等,然后根据飞行高度曲线对得到的结果进行加权平均,得到最终的弦长分布和桨距角分布,建立了三维模型。 The paper designs a propeller of a certain type of solar powered aircraft with high efficiency in the entire flight span. According to given flight speed, propeller diameter and required pulling force, combined with the flight height curve of solar powered aircraft, the number of blades, airfoil And the propeller speed, the chord length distribution and the pitch angle distribution of several design height points are calculated, and then the obtained results are weighted and averaged according to the flight height curve to obtain the final chord length distribution and the pitch angle distribution. A three-dimensional model .
