摘要

In this study, the aeroelastic stability analysis for the overexpanded nozzles has been performed using the numerical coupling via the transpiration method. The results show that a linear approach for the small displacements is usually sufficient for the dynamic instabilities prediction. However, the ulterior evolution of the structure behaviour involves necessarily a nonlinear modelling, and the method of transpiration becomes inoperative.
