[en] This paper is part of a study investigating the prediction of aeroelastic behaviour subjected to
non-linear aerodynamic forces. Of interest here is whether the sub-critical vibration behaviour
of the aeroelastic model gives any information about the onset of the LCO. It would be useful to
be able to use system identification methods to estimate aeroelastic models that characterise the
LCO. Such a methodology would be very useful, not only for analysis with coupled CFD/FE
models, but also during flight flutter testing.
In this paper, the responses to initial inputs on the Goland Wing [9] CFD/FE model at different
flight speeds are analysed to determine the extent of the non-linearity below the critical onset of
LCO. Analysis is also performed using a linear identification model.
