Abstract

An experiment was performed aboard a sounding rocket on a long cylindrical liquid bridge, aiming at discerning the real transfer function of this liquid configuration to small acceleration loads, quantified by the liquid free-surface deformation divided by the axially imposed acceleration. The results were, however, in great discrepancy with theoretical predictions, showing asymmetric jumps of high amplitude in the evolution of the radial deformation of the liquid bridge, instead of a symmetric sinusoidal radial deformation (axisymmetry was preserved). It has been found now that a non-linear dynamic model perfectly explains this unexpected behaviour.
