Abstract: In this follow-on study, macro fiber composite actuators are used to change the shape of the upper surface of an airfoil model with geometry close to that of the NACA 4415 type. In the design discussed, these thin and light piezoelectric actuators are bonded to the inside and become an integral part of the skin of the upper surface of the airfoil. The model used in this study incorporates some structural changes that allow a smoother shaping of the surface closer to the leading edge of the airfoil. Still-air and wind-tunnel measurements in different flow regimes are performed to assess the characteristics of the deformation of the upper surface. The results obtained can be used to design a wing with morphing upper surface for improved aerodynamics, for maneuvering without ailerons, and/or for active control of the flow over the wing. © 2012 by Temasek Laboratories - National University of Singapore.
