Abstract

In this paper, we describe the new methodology and the results obtained for multiple flight conditions optimization of the airfoil of the S4 unmanned aerial system, using a morphing wing approach. The goal of reducing the airfoil drag coefficient over a broad range of speeds and angles of attack has been achieved using an in-house optimization tool based on the relatively new Artificial Bee Colony algorithm, coupled with the Broyden-Fletcher-Goldfarb-Shanno algorithm to provide a final refinement of the solution. The obtained results were validated with an advanced, multi-objective, commercially available optimizing tool. The aerodynamic calculations were performed using a 2D linear panel method, coupled with an incompressible boundary layer model and a transition estimation criterion, to provide accurate estimations of the airfoil drag coefficient. For very small displacements of the airfoil surface, less than 2.5 mm, drag reductions of up to 14% have been achieved for a wide range of different flight conditions.
