An aerostructural numerical model of a two-dimensional morphing laminar wing prototype is built and validated for different flight conditions: Mach numbers ranging from 0.2 to 0.3 and angles of attack ranging from -1 to 2C. The active structure of the wing is modeled using the ANSYS commercial finite element software. The aerostructural interaction is achieved by coupling the XFoil free-license aerodynamic solver to ANSYS. This model is used to minimize the drag force under constant-lift conditions during wind-tunnel testing using a two-step optimization algorithm (global and local search). The wake pressure wind-tunnel measurements show that extrados morphing results in an average 18.5% drag reduction for eight flow cases covering the flow condition range of interest. Simultaneously, the infrared thermography measurements record an average laminar flow extension of 25% of the wing chord over the upper wing surface. The experimental and numerical results are in good agreement, thus validating the use of an aerostructural model to efficiently manage the shape of a morphing laminar wing.
