The stability of blades and wings is considered in this work, the natural modes of the thin blades and wings in incidence under the action of aerodynamic forces are computed. The wing in this study has two degrees of freedom corresponding to the bending and torsion. The variation of the unstably modes versus the far flow field velocity is predicted, in particular, the effects of the variation of the chord on the stability is examined . Wing stabilisation by piezoelectric material are considered.
