植保无人机旋翼对雾滴沉积量的影响

Influences of Rotor of Unmanned Aerial Vehicle for Plant Protection on Droplets Deposition

为了探究植保无人机的喷施效果,进行了多旋翼植保无人机在不同高度下和旋翼处于不同状态下对雾滴沉积量影响的试验。结果表明,当旋翼不工作时随着高度的升高,沉积量下降,而当旋翼工作时雾滴分布趋于均匀,雾滴沉积范围加大,但雾滴沉积量显著减少。

To explore the spraying effect of unmanned aerial vehicle （UAV） for plant protection,tests of influences under dif- ferent heights and conditions on the droplets deposition were made on rotor of UAV. The results showed that when the rotor does not work,droplets deposition decreases with the increase of height,and when the rotor works,droplets tends to be more u- niform and deposition scope tends to be wider,but deposition volume decreases significantly.
