Zusammenfassung:As part of our effort to design and validate a test procedure to determine the shock classification of rocket motor propellants, extensive computer modeling has been performed. This modeling has examined various experimental configurations to determine shock initiations in a gap test configuration. Design considerations that have been examined include shape and aspect ratio of booster and PMMA gap, as well as the effect of confinement of the propellant. DYNA-2D was used to design an experiment that could be easily performed by different services using commercially available materials and that would satisfy the need to determine 1.1 and 1.3 classification. The objective of this program is determination of shock classification of a propellant using a newly developed test methodology as an alternative to the Technical Bulletin 700-2 revised classification standards. The new test methodology uses more realistic confinement as well as smaller sample sizes. A goal is achieving fundamental understanding of the shock initiation and reaction in the propellant sample.
