However, geometrically nonlinear con\ufb01gurations may develop limit cycle oscillations even before reaching the \ufb02utter boundary. When nonlinear effects are anticipated, post-\ufb02utter analyses have to be integrated into design for preventing undesirable subcritical limit cycles. Therefore, there is a need for computationally fast post-\ufb02utter analysis methods suitable for design applications. Previous work proposed an ef\ufb01cient method for forecasting post-\ufb02utter responses using only a few system calculations or measurements in the pre-\ufb02utter regime. This paper applies the method for investigating the post-\ufb02utter response of a practical geometrically nonlinear wing for various design choices to demonstrate the method suitability for parametric studies.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/02\/IFASD-2019-145.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Cristina Riso, Amin Ghadami, Carlos E.S.
