Design, Analysis, and Verification of a 50-mm Push/Traction Sabot

Abstract

This report presents the design and analysis of a kinetic energy projectile for a 5O-mm cannon using finite element techniques. A combination of push and traction launch concepts was used to configure a sabot for a penetrator that experienced catastrophic failure using a push launch sabot system. A parametric model with both plasticity and nonlinear elements was used to model the projectile that experienced accelerations exceeding 50,000 g's. Experimental tests showed marginal success in that a sabot failure permitted significant plastic deformation of the penetrator. Additional post-test analyses predicted the failure mode and the amount of plastic penetrator deformation demonstrated in the experiments.
