【Abstract】 Reproducibility of internal ballistics caused by sedimentary properties at natural ,low and high temperature of long-working-time sustained SRM with copper sintered wolfram nozzle is analyzed in this paper. The concepts of transient reproducibility and integrated reproducibility, and several prime indexes evaluating the degree of internal ballistic reproducibility are presented in consideration of properties of the kind of motors, which may present reference for design of similar motors更多还原
