RocketMotorTwo Hot-Fire Test Summaries

Many subscale hot-firings were performed at Scaled Composites, LLC between Jun 05 and April 09 to evaluate several different fuels, igniters, injectors, insulators and nozzle configurations, as well as other components and parameters. Based on the results of those subscale firings, the Scaled/SNC team chose a full-scale rocket motor system design and began testing in April 2009. The following list includes summaries of the hot-fire activity of the RocketMotorTwo rockets.
