This chapter presents an aerodynamic optimization for a Morphing Leading Edge (MLE) winglet of a well-known UAV, the UAS-S45. The optimization algorithm is integrated with the modified Class Shape Transformation (CST) parameterization method and had the aim to enhance aerodynamic performance by minimizing drag and maximizing aerodynamic endurance at the cruise flight condition. The optimization scheme was carried out with in-house MATLAB code and by employing the Vortex Lattice Method (VLM) to calculate the aerodynamic properties of the morphing leading-edge winglet. This study presents the optimization technique and compares winglet geometries results by demonstrating that changing the winglet geometry in flight can enhance aircraft performance while lowering drag, therefore the fuel consumption. The optimized airfoils have shown a significant improvement in the overall aerodynamic performance by up to 8.55% drag reduction and 10.20% increase in aerodynamic endurance, as compared to the reference airfoil. Therefore, the results indicate the importance of leading-edge morphing in enhancing the aerodynamic efficiency of the UAS-S45 airfoil.
