Optimization method of aerodynamic characteristics for variable thickness wing
摘要
Abstract
In order to maintain great aerodynamic characteristics of aircraft under different flight conditions,an optimization method of aerodynamic characteristics for variable thickness wing is proposed.Firstly,using NACA0012 as the design airfoil,which is parameterized by CST method,Isight integrated XFoil is used to optimize the target airfoil.The optimized airfoil parameters are obtained and aerodynamic characteristics are analyzed.Secondly,based on the optimization results,combined with the analysis of aerodynamic characteristics of the airfoil by Fluent,the surface pressure distributions before and after the change of the variable section thickness of the airfoil are obtained.The results show that for the NACA0012 airfoil,when the flight Mach number is 0.3 and the angle of attack is 10°,the lift-drag ratio can be increased by 13.06％after deformation optimization.关键词
