Abstract:

Newtonian impact theory is used to examine the variation in ballistic coefficient of a coated cylinder as the thickness of the coating decreases. It is shown that when the density of the coating is less than one-half that of the core-material, an initial value of coating thickness can be chosen which results in a steady increase of the ballistic coefficient as the thickness of the coating tends to zero. The largest such value of coating-thickness, the corresponding minimum value for the ballistic coefficient, and the rate at which the ballistic coefficient rises to that of the bare core are shown to be simple functions of the particular density-ratio.
