The thesis presents a mechanical numerical analysis of a model aircraft wing for the university aviation competition DBF (Design, Build and Fly) in the Ansys software environment using Ansys Composite PrePost (ACP). The purpose of the numerical analysis is to evaluate the state of stress and deformation in the composite aircraft wing under specified loads. Using the XFOIL program, we calculated the characteristics of the selected NACA 2412 airfoil. Based on the pressure distribution on the airfoil, we calculated the loads for performing maneuvers equivalent to a gravitational force of 10 G. We analyzed the wing deflections and evaluated the distribution of stress and deformation in the critical parts of the wing. Various failure criteria, such as the maximum stress, deformation criteria and Tsai-Wu, were applied to verify the load-bearing capacity. In the final section, we addressed design and manufacturing errors, possible improvements and the manufacturing technology employed to produce the aircraft wing.
