Abstract

Considering the catastrophic potential of aeroelastic phenomena and its natural importance in the aircraft design phase, this work aims to provide a tool called AseS -Aeroservoelastic Solutions, which aims to enable initial computational aeroelastic analysis in simplified aircraft models, in order to facilitate the study and understanding of how different flow conditions and system geometry affect a given assembly, still in its design phase. At first, a dynamic aeroelastic stability analysis was implemented on an airfoil model with two degrees of freedom (torsion and bending) which is subjected to an airflow of known velocity and density. The aerodynamics involved were considered stationary. In order to enable iterations with possible users, the code developed on the Matlab platform is integrated into an interface, in which the data associated with the two-dimensional 2GDL model can be modified according to the user’s needs. After receiving the data, the characteristic eigenvalue problem is assembled and solved, which provides the dynamic type aeroelastic stability analysis. From this analysis it is possible to obtain the classic V-g-f diagram, which allows the user to develop a visual notion of how the dynamic aeroelastic phenomenon flutter is configured in the analyzed speed range. With such information, a preliminary estimate of flutter-free aeroelastic envelopes can be made. In its continuation, the AseS platform foresees the implementation of other capabilities, both in terms of more complex structural models and in terms of the analysis of other aeroelastic phenomena.
