| This research is focused on experimental and analytical methods of determining the aerodynamic forces acting on a micro air vehicle (MAV) with adaptive wing geometry (morphing geometry). The goal of this design is to modify the camber and thickness of its wings by using smart materials in order to achieve the optimum autonomy or range during the flight phases. Therefore, the most relevant morphing configurations have been studied. They were designed and manufactured at Technical University of Madrid (UPM) by means of additive manufacturing and tested in a low speed wind tunnel at National Institute of Aerospace Technology (INTA). Particle Image Velocimetry was used to study the wake structure of the different morphing configurations. The experimental tests were performed with a freestream velocity of 10 m/s for several angles of attack, from 0º to 30º. Two theoretical methods were applied: integral of transversal kinetic energy and Maskell?s theory; for determining the induced drag coefficient and lift coefficient, respectively. A complete qualitative and quantitative study of the trailing vortex system behind the model is given in order to understand the aerodynamic behaviour of the morphing geometry. | |
