【Abstract】 A study on axially segmented prpellant loading technology for a solid rocket motor with dual thrust in a single chamber is performed. The results indicate that a rotable plate valve with a novel structure, a secondary demountable mandrel and techniques of both scraping and coating of insulation and automatic weighing of propellant slurry to be loaded are adopted so that the design requirements for propellant loading can be met.更多还原
