We consider the problem of active reduction of the structural vibrations induced by the sloshing of large masses of fuel inside a partly full tank. 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. After deri...

A spectral/hp element code, incorporating a velocity-pressure formulation, is used to simulate free surface flows. Non-linear pressure and velocity boundary conditions are applied on the moving free surface, the tracking of which is facilitated by the implementation of an Arbitrary Lagrangian Eulerian (ALE) formulation. The derived algorithm is validated by comparing the numerical results evalu...

Abstract All aircraft are subject to a range of loading throughout ground and flight operations, which ultimately define the sizing weight structure. Active passive loads alleviation technologies provide an approach reduce dynamic arising from atmospheric gusts turbulence, leading more fuel-efficient designs. Within H2020 SLOWD project, fuel sloshing is being considered as method for alleviatin...
