摘要：

A simplified efficiency analysis of a laminar morphing wing as a path to further economic impact evaluations has been developed. The energy saving from drag reduction, both reference and morphed profiles are analyzed by the boundary-layer solver XFOIL. The 3-D finite element model of the active structure is built in ANSYS software using SHELL99 elements for flexible structure and SHELL63 for compensation leaf spring with locked rotation to ensure slope profile continuity. The drag coefficient and the location of the laminar-to-turbulent flow transition point are calculated for each flow case. The preliminary analysis reveals promising results that need to be validated through subsequent wind-tunnel testing. Various graphs have also been given to support the active-extrados morphing laminar wing.
