Morphing wings, which can deform according to the flight conditions, have attracted much attention because of their potential for improvement in aerodynamic or environmental performance. Many studies have contrived flexible structures for the morphing functions, but they need fluid-structure interaction (FSI) analyses for evaluation. In this paper, a new FSI model that has an excellent balance of time cost and reliability of analyses is suggested. A CFD solver UTCart is used instead of XFOIL, which was adopted in the previous work. It is shown that UTCart outperforms XFOIL in reliability of analyses while XFOIL excels in time cost. The combination of the two solvers, where the aerodynamic calculations in the iteration loop are done by XFOIL and the final calculation of the aerodynamic properties is done by UTCart, is found to be a good model for the FSI calculation.
