Abstract
In recent years,with the rapid development of agricultural plant protection UAVs,the problems of chemical loss and pollution during their operations have become increasingly prominent.In view of the current research on droplet drift and deposition characteristics during plant protection UAV application,there are single research methods,unclear mechanisms of the influence of droplet deposition and movement characteristics,and lack of in-depth investigation of the deposition and movement process from the perspective of droplet microdynamics.Therefore,this paper mainly summarizes the research status of basic theories related to the spray droplet motion characteristics of plant protection UAV,including the mechanism of agricultural aviation droplet drift law,the influence mechanism of droplet motion characteristics,and the spatial characteristics of two-dimensional visualization spray flow field,and puts forward suggestions for the future research direction of spray droplet motion characteristics of plant protection UAV,in order to provide reference for the follow-up development of precision pesticide application technology of plant protection UAV.关键词
