Annotation: Morphing wing technology enables improvements in an aircraft’s aerodynamic performance by adapting to different flight conditions. Such technology can enhance flight performance, controllability, and reduce fuel consumption. This work aims to develop geometry formation algorithms designed for a compliant morphing wing trailing edge structure, which, when subjected to control loads, achieves an optimized aerodynamic shape. Two algorithms were developed for this purpose. The first algorithm mathematically describes the outer geometry behavior of a compliant morphing trailing edge for the generation and optimization of aerodynamic shapes. The second algorithm, based on the optimized external geometry of the flap, generates a compliant monolithic trailing edge structure capable of obtaining the desired aerodynamic shape under defined control loads. The developed algorithms allow the formation of trailing edge structures that can adapt to more than one aerodynamic shape under different control loads and aerodynamic conditions, significantly expanding aerodynamic optimization capabilities. The structural formation methodology is based on a two-dimensional wing section and accounts for aerodynamic loads, structural strength requirements, and the potential occurrence of aeroelastic phenomena. Experimental investigations confirmed the accuracy of the developed algorithms and demonstrated that the proposed methodology can increase the aerodynamic performance of a wing with a compliant trailing edge by more than 12% compared to conventional flaps.
