摘要
近年来农用植保无人机的迅猛发展,其作业过程中的药液流失、污染问题日益凸显。针对当前植保无人机施药过程中的雾滴飘移与沉积特性研究存在的研究手段单一、雾滴沉积运动特性影响机制尚不明晰、缺乏从雾滴微观动力学角度深入探究其沉积运动过程的问题,该文主要综述植保无人机喷施雾滴沉积运动特性相关基础理论研究现状,包括农业航空雾滴飘移规律的作用机理、雾滴沉积运动特性影响机制、二维可视化喷雾流场空间特性等研究现状,为植保无人机喷施雾滴沉积运动特性未来的研究方向提出建议,以期为植保无人机精准施药技术的后续发展提供参考。
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.
