Summary on Grant Application Form
Over the past decade there has been a pronounced increase in research concerning nonlinear aeroelasticity. Nonlinearities give rise to phenomena su as Limit Cycle Oscillations (LCOs) that cannot occur if the system is linear. Current industrial practice completely ignores nonlinearity. However, Limit Cycle Oscillations do happen and, even though they are not as catastrophic as flutter, they can reduce the performance of an aircraft as well as seriou increase the probability of fatigue failure. The aim of this project is to investigate the capacity of commercial and experimental CFD packages to simula accurately unsteady nonlinear aerodynamic phenomena and their effects on aeroelastic structures. The suitability of such packages to be used for the prediction aeroelastic instabilities due to aerodynamic nonlinearity will also be investigated.
