Embodiment Construction
[0060] In order to better illustrate the purpose and advantages of the present invention, below, the present invention will be further described in conjunction with the accompanying drawings and tables through the wing airfoil optimization design example and the general-purpose aircraft overall parameter optimization design example, and by comparing with the traditional optimization method results, the present invention The comprehensive performance of the invention is verified and analyzed.
[0061] (1) Optimal design of wing airfoil
[0062] The optimal design of airfoil is of great significance to improve the overall performance of aircraft. With the development of computer technology, Computational Fluid Dynamics (CFD) technology is widely used in airfoil optimization design. In this optimal design example, the CST method is selected to describe the coordinate points of the upper and lower surfaces of the airfoil. In this example, NACA0012 is selected as the initial airf...
