Side moment exerted by a two-component liquid payload on a spinning projectile
Abstract
A linear boundary layer theory is derived for two liquids in a cylindrical cavity in a coning and spinning projectile. Predicted eigenfrequencies agree well with available experimental results. Side moment coefficients are computed for various cases. It is shown that large changes in the side moment can be caused by a small amount of liquid and for certain locations of the liquid interface, pairs of eigenfrequencies can coalesce.
