Implementação de uma plataforma para análises aerodinâmicas não lineares de aeronaves de geometrias complexas em regime subsônico.

Abstract

The present work expose the methodolgy used in the development of the aerodynamic module of a preliminary aeronautical project platform for subsonic aircraft of arbitrary geometry. The mathematical modeling, their simplifications, and the numerical methodology used in the implementation are detailed. The aerodynamic modulus is based on potential flow theory, being able to quickly simulate sets of arbitrary lifting surfaces in asymmetrical regime, close to the stall by means of the Vortex Lattice method with viscous corrections. Different types of wake modeling and mesh are implemented. The results are confronted with cases present in the literature, for different flight regimes and different geometric configurations, showing good agreement. Due to the low computational cost of the code and its flexibility in the creation of geometries, it proved suitable for optimization routines,as well as for the incorporation in algorithms of flight mechanics, performance and aeroelastic loads.
