Propostas de melhorias a projetos estruturais da equipe Tucano para competições

Abstract

The development by the Tucano Aerodesign team of the structural design of a cargo-controlled aircraft for SAE Brasil Aerodesign competition requires constant improvements, due to the high level of the participating teams. For this reason, there was a need to develop analytical methods, capable of improving the results obtained in the initial stages of the project. It was also noted that the time taken to create drawings, necessary for numerical simulations, took up much of that devoted to modeling. For this reason, two tools have been developed: a structural optimization of wings, based on the idealized by booms and an assistant for importing profiles and creating wings. The first, built in MATLAB ®, requires user input on the wing geometry, aerodynamic profiles used and number of ribs. Its answer is the mass of the wing. In addition, its structural arrangement, dimensioning and loading are also informed. The second, made in VBA language, needs information about the aerodynamic and structural geometry of the wing, coming from, for example, the structural optimizer, and is capable of executing all the processes necessary for its design. The results obtained demonstrate that the optimizer is capable of providing values close to those observed by the FEM method, therefore being suitable for the initial design stages. The aid for creating wings showed the ability to be used in the most diverse geometries, number of sections on the wing or types of aerodynamic profiles used.
