A single grain rocket motor was designed to be used in a shelf life assessment and extension program for a solid double-based propellant multigrain rocket motor. The qualification of the single-grain rocket motor has been performed through several static firings to measure the different ballistic characteristics at different temperatures. The purpose of such qualification firings was to approve the suitability of the design of the single-grain rocket motor to give comparable ballistic performance to the multi-grain rocket motor, which should match the original specifications of such motors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
