Some proposal for modelling the main components of a drone-mounted vineyard pesticide sprayer circuit

Using drones in agriculture often makes it possible to change or to improve operations such as pesticide spraying. This paper presents an analysis of several commercial spray nozzlesconducted in order to design a drone-mounted vineyard spraying circuit. In particular, thepaper illustrates several models of these nozzles developed on a commercial software platform. These models were used to analyze the behavior of different nozzles on the basis of catalog data, thus making it possible to design and optimize the spraying circuit before components are purchased. These models were investigated in different ways, and the preliminary results obtained were compared with those from experimental tests. The comparison yielded good results.
