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 significant increases in the single-liquid side moment can be caused by the addition of a small amount of heavier liquid and for certain locations of the liquid interface, pairs of eigenfrequencies can coalesce.
