Impact Testing of Heat Source Exemplars

Hansen, A.; Farfan, B.; Cockreham, Brett D.; Schecker, Ryan; Alexander, Charles S.; Martinez, John R.

This report details the heat source impact testing performed at the Shock Thermodynamics Applied Research Facility (STAR). The purpose of these tests were to measure the impact behavior of a heated Ta-10W tantalum/tungsten alloy heat source exemplar. Each exemplar resembled a cylinder with a rectangular through-hole orthogonal to the cylinder axis-of-symmetry. In each test, the exemplar was impacted by a hardened steel impactor accelerated using the STAR air gun. The exemplars were impacted ...
