    摘要:

    太阳能无人机“超高空、超长航时”的设计方向给螺旋桨的气动设计带来了极大挑战。根据某太阳能 无人机总体方案,使用多点多目标优化方法改进设计桨叶翼型,合理布置叶宽分布与桨距,设计出低雷诺数工 作环境下的高效螺旋桨,并利用叶素理论对该设计方案进行性能评估。结果表明:本文设计的螺旋桨在全飞行 包线内均可保持较高的气动效率,各项指标满足设计要求。

    Abstract:

    High Altitude Long Endurance (HALE) solar powered unmanned aerial vehicle has the design characteristics of low Re number which makes a great challenge to the propeller aerodynamic design. Based on the main design of a UAV, a solar powered propeller is design in this paper. Multi variables optimization method is used to design the blade element. With proper blade width and pitch distribution, the propeller works efficiently in low Re number. The propeller aerodynamic characteristics are validated in BEM method. The calculation shows the propeller has a high efficiency of over 85% in cruise.
