Embodiment Construction
[0051] In order to make the purpose, technical solution and advantages of the invention clearer, the invention will be further elaborated below in conjunction with the accompanying drawings.
[0052] In this example, if figure 1 Shown, a kind of adaptive wing airfoil design method, this method comprises the following steps:
[0053] Step 1: Select the RAE2822 airfoil as the initial airfoil, and use the CST parameterization method to obtain the parametric description of the initial airfoil;
[0054] Step 2: Determine the optimal design variables for local deformation, and use the main weight coefficients affecting the camber part as optimization variables;
[0055] Step 3: Select an optimization algorithm to initialize the population;
[0056] Step 4: Process the initial population to obtain the lift coefficient C L When = 0.9, the maximum lift-to-drag ratio and the minimum maximum bending stress after the leading edge camber is changed are the optimization goals, and no axi...
