      The problem on Raleigh-Taylor instability of the interface between fluid and elastic body has been analyzed. An analytic solution is obtained in linear approximation for the case of the uniform and pulsed acceleration joint effect. The solution obtained is not a simple superposition of solutions for the cases of either uniform or pulsed accelerations. On the contrary our solution contains these particular cases. The relationship of the perturbation amplitude to time for the water-rubber interface is analyzed by the way of example assuming the ideal character of both media.
