摘要

This paper presents a preliminary study on flutter boundary prediction of a smart adaptive aeroelastic multimode system, in which flutter takes place due to a coupling between higher aeroelastic modes during the process of structural adaptation, while the flow speed is kept fixed. In such a new situation the conventional damping method would hardly work well. The prediction approach based on Jury's stability criterion in the discrete-time process will be applied. Numerical results show that Jury's criterion is much more effective in predicting the flutter boundary than the damping coefficient of the flutter mode.
