The effect of non-linearities, be they structural, aerodynamic or control, on the aeroelastic behaviour of aircraft is becoming of increasing importance in the Aerospace industry. As well as the prediction of flutter instabilities, there is a need for the prediction and modelling of the onset of Limit Cycle Oscillations (LCO). A thorough understanding of lhe possible types of aeroelastic phenomena that can occur due to non-linearities in the system is required before attempting to predict the behaviour. In this paper, the onset and suppression of LCOs is investigated by means of an examination of the stability and energy content of limit cycles.
