N2 - Following G.I. Taylor and our own previous work based upon it, we continue to explore HE confiner motion as test diagnostic. A handful of authors (including us) have adapted Taylor's analysis to infer equation-of-state information from detonation cylinder tests. We have also successfully applied this class of analysis to deflagration cylinder tests (DFCTs). Here, we analyze a miniature DFCT diagnosed by multiple PDV probes. We spatially interpolate between PDV records to obtain a smooth function for lateral expansion vs. axial distance, z, and time, t. From this we may construct snapshots of the tube at any time; hence we may create animations of the tube motion and compute the product gas volume V vs. t. Combining Newton's law with simple stress theory, we estimate the gas pressure P vs. z and t. We then estimate the burned HE mass from the wall kinetic energy. Finally, we discuss some important test scaling issues.
