Abstract

In order to explore the influence of aerodynamic characteristics on aircraft flight performance and analyze the effect of attack angle on the aerodynamic performance of NACA0018 airfoil, numerical simulation of NACA0018 airfoil has been established by using FLUENT software. Firstly, by comparing the results of computational models and experimental values, the numerical boundary conditions and turbulence models applicable to airfoil calculations were determined. Secondly, combined with the principle of lift improvement, the pressure and velocity field of NACA0018 at 0 ° and 4 ° two attack angles were analyzed. The experimental results show that increasing the attack angle can significantly improve the lift, that is, the lift of the airfoil at a 4 ° attack angle is greater than that 0 °. This study provides a reference for wing design and aerodynamic performance analysis, which can optimize wing shape and structure based on changes in attack angles under different flying conditions. In the future, further research will be conducted on the matching between wing attack angles and wing types, flap lengths, flap deflection angles during different flight stages, in order to optimize the aircraft performance comprehensively.
