Projeto aerodinâmico de asa para aeromodelo de competição SAE Aerodesign

Abstract

The SAE Brazil AeroDesign competition challenges university students to design and build aircraft, requiring in-depth knowledge of aerodynamics, avionics, control, and structure. This work focuses on the design and optimization of the aerodynamic performance of an aircraft wing for a team competition, through detailed aerodynamic analyses of different wing profiles, using the panel method in the software XFLR5. The research involves consulting the literature on the wing foils most commonly used in the competition and two-dimensional aerodynamic simulations to select the ideal foil, as well as a study of the stall performance of the foil with adjustments to the geometry for improvement. The methodology used was developed together with the team in order to analyze lift, drag, moment, and stall of the wing foil, with the goal of designing a finite wing. Based on the analysis, a new wing foil was developed for the team. The finite wing was dimensioned and used in the 27th edition of the competition, opening the door for future, more comprehensive three-dimensional analyses in order to improve the aircraft's performance in the SAE Brasil AeroDesign competition.
