A Detailed Physical Explanation of an Aircraft Flutter Mechanism

Luiz Felipi Ribeiro Siqueira, Marcelo Santiago de Sousa, Flávio Luiz Cardoso-Ribeiro & Sebastião Simões da Cunha Junior · Archives of Current Research International · 2024

Each dynamic mode (aeroelastic) is made up of torsional and rotational movements. These two movements in each mode were dissociated and the phase, amplitude, damping and frequency of each of these movements were analyzed.  The structural resistances of torsion and bending, as wel...
