Structural response of earth penetrators with angle of attack impact
The Pershing II earth penetrator program has utilized sub-scale and full-scale penetrators impacting various targets at high velocity. Testing has included reverse ballistic techniques in which the target is propelled into a stationary instrumented penetrator. Full-scale penetrators have been launched from a 30-ft long, 12-in. bore, Davis gun. Analytical predictions for the structural responses have been made for various penetrators and test conditions. The predictions are for angles of attack of 2 and 3 degrees into various targets. The SHELL SHOCK structural code was used for the analysis. The code is intended for analyzing three-dimensional axi-symmetric structures. The modeling of the penetrator requires that the axial response of the components are uncoupled from the penetrator case, but lateral coupling is required between the components and case for the angle of attack loading. Comparisons are made between the analytical predictions and the experimental results.
