COMMENTS ON THE ONERA STALL AERODYNAMIC MODEL AND ITS IMPACT ON AEROELASTIC STABILITY

The present comments address the fundamental dynamic behavior of the O NERA aerodynamic model and consider the interacting dynamics of that f low model with a simple structural model, the typical section, A class ical linear flutter analysis clarifies and deepens our understanding o f the change in the character of flutter from the unstalled to the sta lled flow regimes. The change in modal participation, including both s tructural and aerodynamic eigenmodes is highlighted. (C) 1996 Academic Press Limited
