Python Language Applied to Flutter Analysis in a VANT‘S 3D Wing.

Resumo

Flutter is one of the most well-known dynamic aeroelastic phenomena, known for its destructiveness
and frequently associated with thin structures and less rigid materials, and has been widely used in the evolution
of the aeronautical industry. The SAE Aerodesign competition simulates the design of UAVs - Unmanned Aerial
Vehicles - and includes the study of the probability of aeroelastic phenomena in the project to qualify students
and enthusiasts in the field. Aiming to enlarge access to Flutter analysis occurrence by students and produce an
efficient study of the Flutter Critical Speed, the Python language was applied to create a program able to interact
with the Aerodynamics through the Panel Method and the structural behavior by the Grid Method and return the
Critical Speed calculated according to Method K, generating the V-G Diagram of the aeroelastic behavior of the
plane. The wing of the UAV designed by Araras Aerodesign team in the system with two degrees of freedom was
used as an example. The code was efficient in generating the expected result, checked according to the literature,
and compared with commercial software.
