The problem of active reduction of the structural vibrations induced by the sloshing of large masses of fuel inside partly full tank is considered. The proposed study focuses on an experimental device mimicking an aircraft wing made of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid. First, a representative...
We consider the problem of active reduction of vibrations in a fluid-flexible structure system. In the aerospace domain, we are actually interested in the system that couples the deflection of a plane wing and the sloshing of the fuel inside the wing's tank. The control is performed using piezoelectric patches and the main difficulty comes from the complex coupling between the flexible modes of the...
