EXPERIMENTAL OBSERVATIONS OF THE DYNAMIC BEHAVIOR OF LIQUID FILLED SHELL

Abstract

Experiments with a 20mm M56 shell whose cylindrical cavity, fineness ratio 2.7, was filled with different amounts of various liquids demonstrated the existence of dynamic instability for a broad range of loading conditions. It was found that, for water-like liquids, the nutational component of yaw is divergent when 40 to 90% of the cavity is filled. For Hg, the yaw is divergent from about 25 to 100%. The severity of instability or the rate of divergence of yaw increases with the increase in the specific gravity of the liquid.
