| Abstract | The small-perturbation theory is proposed to explain aerodynamic instability. The two possible approaches, quasi-steady and unsteady, have thus far exhibited certain limits in yielding satisfactory results, the reasons for which are explained herein. Use of the Alternating Direction Implicit method for the numerical solution of the model highlights the significant differences in the quasi-steady and unsteady approaches and also allows good definition of shock positions.
