Abstract

The article discusses the possibility of applying precision and smart agriculture while reducing the environmental impact of chemical treatments, associated with drones that form highly dispersed droplets. This allows for the protection of agricultural, medicinal, and other plants from pests and diseases, as well as targeted fertilization with liquid mineral fertilizers during the growing season, ensuring uniformity of nutrient concentration. The targeted use of drones in various agricultural operations can reduce labor requirements and also decrease working time. The hydraulic systems of UAVs and their working elements are aimed at improvement and are relevant issues of today. In addition, with the help of a special camera installed on the UAVs, image processing over the internet and machine learning algorithms assists in studying the precise results of agricultural activity, future achievements, shortcomings, and challenges. The article also examines the hydro-and aerodynamic forces acting on a thin curtain of liquid ejected from the annular slot of a turbulent tedder developed by the authors. This technological process investigates the stages of destruction of a two-phase (air-droplet) jet, resulting in the formation of large droplets, the physical essence of the Weber number, and elaborates on the likelihood that small droplets have probabilistic characteristics. The ability of the working medium to break down under the influence of modifiers is assessed by the increase in the Weber number. (10≤ We_кр ≤ 10⁵). Using the UAVs, it was found that for fan spray nozzles the Weber number We=42, while for the proposed turbulator spray nozzles during the spraying of two-phase flow We=85, which confirmed the validity of the working hypothesis.
