A influência do arqueamento do perfil de aerofólio nos coeficientes aerodinâmicos para aplicação em aerodesign: uma análise numérica

Abstract

This study aims to investigate the influence of airfoil profile geometry variation on key aerodynamic coefficients, particularly how the variation of an airfoil’s camber affects the lift, drag, and moment coefficients, with a focus on applications in the aerodesign niche. Through computational numerical analysis, using the panel method due to its lower computer processing requirements via the XFLR-5 software. Derived profiles based on the NACA 0012 airfoil were simulated, with the new profiles having cambers of 2%, 4%, 6%, and 8%, respectively, conducting quantitative and qualitative analysis of the obtained values for a fixed angle of attack at 10°. The results show that the lift coefficient increases proportionally with camber and can be modeled by a recurrence formula based on the statistical tool control chart. On the other hand, the drag and moment coefficients also increase, but in a non-linear manner and without a pattern predictable by the same methodology. The study concludes that the lift coefficient can be mathematically modeled as a function of the airfoil’s camber; however, further complementary studies are recommended for the drag and moment coefficients.
