Abstract
Main landing gear doors cover the main landing gear bays, keeping the aerodynamic shape of the aircraft during flight. They are open/close on each landing gear retraction/extension. During these phases, the nose landing gear creates flow separations, characterized by turbulent vortex motions. This turbulent flow is responsible of unsteady aerodynamic loads on the main landing gear doors and may lead to vibrations (buffeting). The present work summarizes the key activities carried out to characterize the structural response of the main landing gear doors of a commercial transport aircraft. Control devices designed, manufactured and flight-tested in order to mitigate their vibrations.
