The modal-based model is solved for the amplitude and period of the limit cycles of the \ufb02at plates using numerical continuation. The resulting predictions are compared to experimental data obtained from identical \ufb02at plates in the wind tunnel. It is shown that the aeroelastic model predicts the linear \ufb02utter conditions and nonlinear response of the plates with reasonable accuracy, although the predicted limit cycle amplitude variation with airspeed is different to the one measured experimentally due to unmodelled physics.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-075.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>N.
