Abstract : A sabot trajectory analysis is performed on three hypervelocity kinetic energy penetrators using a modified version of a code developed to compute sabot discard trajectories. The code was modified from the original version to allow computed trajectories of more complicated sabot designs. Specifically, modifications were made to the front scoop geometry and associated aerodynamic model. The computed trajectories are compared to experimental data obtained in the Institute for Advanced Technology's Hypervelocity Launch Facility and to predictions made with the original version of the code to assess the overall accuracy of the code and the improvements of the modifications. Additionally, an analytical model is developed to verify the trends predicted by the computer code and to help identify possible improvements to the pressure modeling in the code.
