“…Agrochemicals application is one of the most critical issues of the current agricultural production system (SILVA et al, 2015;YANAGIHARA;BRAGAGNOLO, 2018), being an obstacle that raises the production cost and can lead to direct and indirect damages to the environment (WACHTEL et al, 2019) and the agriculture workers (JUNQUEIRA; CONTRERA, 2018).…”

In recent years, the Brazilian agriculture production expanded by 900 % over 1990, while the cultivated areas increased at a rate of 2 % per year. Due to this expansion, pulverization turned from manual to mechanical using ground equipment and aircraft. As a result of the new tendencies, recent statistics show the negative impacts on the health of pilots and operators of terrestrial machinery and on the environment. The present study evaluates the concept of an unmanned aerial vehicle (UAV) for pulverization of defensive products, named here as AVANT. In this study, new airfoils are evaluated, lifting line technique, vortex and panels method are used to define the geometry of the wings, fuselage and tail elements. Simulations were realized to verify the performance of the AVANT during operational shots and maneuvers. The basic parameters of the proposed AVANT are, Wingspan: 6 m; Monoplane;
