The limit cycle #utter of a two-dimensional wing with non-linear pitching sti!ness is investigated. For modelling the aerodynamic forces of the wing steady linear and non-linear models as well as an unsteady model were used. The #utter speed was calculated using the harmonic balance method and by pr
