Desenvolvimento de um software de apoio à otimização do dimensionamento preliminar aerodinâmico aplicado a projetos de aerodesign

Abstract

This work aims to develop a computational tool to support the preliminary design of the aerodynamics subsystem applied to aerodesign aircraft, with a focus on automating the calculation of geometric and aerodynamic parameters related to the wing and the tail assembly. The tool, named AeroCalc, was implemented in the Python programming language, using a graphical interface developed in Tkinter, and its calculation modules were structured based on consolidated foundations from the aeronautical engineering literature. The software processes parameters associated with the S1223 RTL airfoil and the NACA 0009 airfoil, allowing the user to input design variables and obtain output results automatically. For validation purposes, AeroCalc was applied to the aircraft projects of the Aratinga Aerodesign team from the years 2024 and 2025, using geometric and aerodynamic data provided by the team. The results obtained by the software were compared with the values presented in the project reports and with the parameters generated in the XFLR5. A high level of agreement was observed between the calculated results, with punctual differences mainly associated with discrepancies between analytical values and values extracted directly from the XFLR5, as in the case of the mean aerodynamic chord. The results indicate that AeroCalc is a reliable support tool for the preliminary design phase, contributing to the standardization of calculations, reduction of analysis time, and systematization of the design process within the context of academic aerodesign projects.
