Abstract

Vertical sloshing of liquid filled tanks has been shown to induce substantial dissipative effects. Building upon these previous results obtained on simpler sloshing systems, here a scaled wing prototype is presented equipped with a fuel tank that allows the observation of liquid sloshing and quantification of induced dynamic effects. Based on experiments conducted at 50\% filling level for a baffled wing fuel tank model, substantial additional damping effects were demonstrated with liquid inside the tank regardless of the vertical acceleration amplitude. A numerical model based on a finite element wing structural model and a surrogate 1DOF fluid model was explored, with numerical simulations showing good agreement compared to experiments throughout the decaying motion of the system.
