Summary

article velocity measurements have been made on samples of TNAZ (1,3, 3-trinitroazetidine) explosive pressed to 98--99% of theoretical maximum density. Measurements were made with magnetic particle velocity gauges and a VISAR interferometer. Stirrup shape magnetic particle velocity gauges were mounted on the front and back of the TNAZ pressing. The back gauge was located at the interface of the TNAZ and a PMMA window and was also used as the diffuse reflector for the VISAR measurement. This allowed the simultaneous measurement of particle velocity by both a magnetic gauge and a VISAR. Well defined inputs to the TNAZ, ranging from 0.6 to 2.4 GPa, were produced by gas gun projectile impact. Unreacted Hugoniot data were obtained from the front gauge measurement and shock transit times through the TNAZ. A linear shock velocity vs. particle velocity fit of U{sub s} = 2.39 + 2.31 u{sub p} mm/μ/s was obtained for the unreacted Hugoniot. An elastic-plastic transmitted wave, similar to that which has been seen in other explosive materials, was observed in the 0.6 GPa input experiment. Considerable amounts of reaction were observed in experiments with inputs of 1.6 and 2.4 GPa.
