Abstract: Morphing airfoil models which use macro fiber-composite actuators (piezo-ceramic type) to the shape of the upper skin were designed and fabricated. The models have shape close to the NACA 4415 airfoil with a chord of 150mm and a span of 158mm. Preliminary measurements have been made of the deformation of the upper skin with different types of actuation. Measurements of the aerodynamic properties have been performed in a wind tunnel at 15 m/s (Re ≈ 150,000) with different types of actuation. The results obtained indicate that aerodynamic benefits can be obtained by changing the shape of the airfoil. This technology can be developed further and used to design a wing with morphing surfaces for improving and maintaining the aerodynamic performance at different flight conditions, for maneuvering without ailerons, or even for active control of the flow over the wing.
