从单室双推力固体火箭发动机的应用、性能、推进剂、壳体材料、成型工艺、推力矢量控制等方面着手,讨论这种发动机的技术现状、应用情况和发展趋势,并同单室单推力发动机作了详细的对比.给出了国内外若干种主要单室双推力发动机的性能数据.今后发展动向:多数单室双推力发动机仍将以采用端羟基聚丁二烯推进剂为主;少烟无铝复合推进剂和微烟的硝胺类改性双基推进剂的应用将会有所增多;发动机壳体仍以采用超高强度钢为主;加快使用推力矢量控制装置.
From the aspects of application, performance, propellant, shell material, forming technology and thrust vector control of single-chamber double-thrust solid rocket motor, the status quo, application and development trend of this kind of engine are discussed. Engine made a detailed comparison.Provide a number of major domestic and international single-chamber double-thrust engine performance data.Future developments: Most single-chamber double-thrust engine will still be based on the use of hydroxyl terminated polybutadiene propellants; Smoke-free aluminum composite propellant and micro-smoke nitramine modified double base propellant applications will be increased; the engine casing is still based on the use of ultra-high-strength steel; accelerate the use of thrust vector control device.
