The aeroelastic parameters and stability conditions are presented as functions of the wind velocity. Random noises are shown to have not only destabilizing but also stabilizing effects. The geometrical forms of their stability domains are identified in frequency plane. Critical wind velocity for flutter and other instabilities is calculated using Routh-Hurwitz criterion applied on the characteristic polynomial of the set of differential equations. Theoretical results are compared with those obtained by experimental measurements in a wind tunnel.
