Computational and Experimental Investigation of Limit Cycle Oscillations of Nonlinear Aeroelastic Systems

A wide variety of pathologies, such as store-induced limit-cycle oscillations, have been observed on high-performance aircraft and have been attributed to transient nonlinear aeroelastic effects. Ignoring the nonlinearity of the structure or the aerodynamics will lead to inaccurate prediction of the...

Zusammenfassung:	A wide variety of pathologies, such as store-induced limit-cycle oscillations, have been observed on high-performance aircraft and have been attributed to transient nonlinear aeroelastic effects. Ignoring the nonlinearity of the structure or the aerodynamics will lead to inaccurate prediction of these nonlinear aeroelastic phenomena.
