Analysis of Long Rod Penetration at Hypervelocity Impact

Abstract

The hypervelocity impact of a long rod penetrator against targets of like material was studied analytically with the aid of the HELP code and the results were compared with experimental data. The computations of projectile residual speed deviated by no more than 3% from the experimental data; of residual mass by no more than 16%; or final rod length by no more than 5%; and of target exit diameter by no more than 8%. This agreement demonstrated that the HELP code can serve as a useful analytical tool for the study of kinetic energy projectile penetration at hypervelocity impact.
