Error analysis of burning-rate measurement procedures

Burning-rate measurement procedures are contrasted, using a round-robin dataset of simulated motor data having either instantaneous or noninstantaneous burnout as the principal variable. Bias error components of two historical procedures are specifically identified and measured. An iterative least-squares group analysis is shown to improve results from the historical procedures by eliminating the effect of nonneutral pressure-time histories. A two-point measurement procedure is shown to produce bias-free results for these simulations.
