The invention provides a design method and device for an unmanned aerial vehicle of an aerial pesticide application rotary atomizer, and the method comprises the steps: screening candidate airfoils with lower stall performance based on lift-drag curves of different airfoils; and determining the airfoil profile of the wind-driven atomization unmanned aerial vehicle according to the candidate airfoil profile. According to the method, the airfoil profile of the wind-driven atomization unmanned aerial vehicle is determined according to the candidate airfoil profile with the low stall performance, the effect at the low speed is equal to that of a conventional rotating cage atomizer, and under the high-speed operation condition, blades stall rapidly to control the rotating speed of a rotating cage and reduce the proportion of small fog drops generated by the atomizer, and finally the purpose of reducing the drifting loss of the fog drops is achieved.
本发明提供一种航空施药旋转雾化器无人机设计方法及装置,该方法包括:基于不同翼型的升阻力曲线,筛选失速性能较低的候选翼型;根据所述候选翼型,确定风驱雾化无人机的翼型。该方法根据失速性能较低的候选翼型确定风驱雾化无人机的翼型,低速下效果等同于常规转笼雾化器,而在高速作业条件下,桨叶迅速失速以控制转笼转速,降低雾化器产生的小雾滴比例,最终达到减小雾滴飘移损失的目的。
