In order to explore the design characteristics of the aspirated airfoil,a new optimization design method which combines artificial bee colony algorithm with Class-Shape-Transformation(CST) method is presented. The MISES code is chosen as the flow field solver. And the feasibility of the CST method applied to aspirated airfoil optimization is demonstrated in detail. Research results show that the coupling optimized design can make the total pressure loss reduction by 65%,and the turning angle increases by 3°...
