Abstract
This work investigates the spectrum distribution of continuous gust loads found in the atmosphere. It is evaluated the effects of a leading-edge flap coupled to the trailing-edge flap for an aeroelastic system with four degrees of freedom. The control surfaces coupling parameter is investigated to determined the stable and unstable system behavior. The different gust configurations are studied and unsteady aerodynamic forces are considered. The equations of motion are written using aeroelastic frequency response functions (FRF) and the system responses are obtained in terms of their power spectral density (PSD).
