Abstract
The objective of the present work was to design, simulate, construct and validate the structural components of the wing of a human-powered aircraft (HPA). The airfoil and wing shape were defined by simulating the flight conditions using the XFLR5 software, through which wing lift load distribution was obtained. Through theoretical research, it was possible to relate shapes, stiffness and density of various materials in order to determine what would be the ideal design of the wing spar as well as the material most suitable for its manufacture. The component parts of the wing were modeled in the NX CAD software and then exported to ANSYS software for finite element method (FEM) simulation. Structural optimizations were made to adapt the characteristics of the wing to the constraints of the project. Finally, two prototypes were manufactured where strength and structural stiffness validation analyzes were performed. A difference of 2.8% in stress and 7.3% in deformation between the values obtained in the experimental tests and the results obtained in the numerical simulations was achieved.
