Abstract
This paper addresses a flutter boundary prediction of a smart wing during the process of adaptation in which airplane's safety will easily be endangered. A smart morphing airplane will be more flexible functionally and mechanically than a conventional airplane with a fixed structural configuration. During the process of structural morphing or adaptation, airplane's structure needs to become very flexible, so that the airplane is anticipated to encounter instability in a new manner due to an on-going structural change. Here we will show that the new discrete-time series approach for aeroelastic instability prediction which we proposed for the fixed-wing is useful in predicting the flutter boundary of an adaptive wing, too. A numerical analysis is performed using a two-dimensional wing model in which the structural adaptation changes its natural frequencies and consequently influences its aeroelastic stability although flying at a fixed speed.
