固体碳氢推进剂在涡轮增压固冲发动机中的应用

摘要

提出了固体碳氢推进剂作为涡轮增压固冲发动机( TSPR)驱涡推进剂的方案,分析了适用于TSPR推进剂的热力参数和一次燃烧产物成分,完成了驱涡推进剂的选择;进行了备选推进剂( CH04)对TSPR性能的影响性评估,证明该推进剂能够满足TSPR的性能要求;对所选推进剂了进行了一、二次燃烧试验,试验结果表明,CH04推进剂在补燃室点火较困难,但其一次、二次燃烧稳定性好,燃气参数基本满足TSPR对推进剂性能要求.%Solid hydrocarbon propellant was proposed to be used to drive turbine of Turbocharged Solid Propellant Ramjet (TSPR).The thermodynamic parameters and the first combustion production of propellant used for TSPR were analyzed to select the suitable propellant(CH04) to drive the turbine. An evaluation for propellant' s influence on the performance of TSPR was per-formed,which proved that the propellant(CH04)meets the requirements of TSPR.The first and second combustion experiments were carried out.The results show that,the first and second combustion have high stability,despite of the difficulty in ignition in the after-burner,and the feasibility of the selected propellant used for TSPR was verified.
