| 摘 要： | 起动系统工作特性是液体火箭发动机研究的重点之一。对于采用火药起动器起动的液体火箭发动机,火药起动器后双喉道管路对起动系统的功效以及发动机的起动性能影响巨大。针对火药起动器以及起动器后双喉道燃气管路建立了计算模型,并通过试验数据对模型进行了验证。利用模型计算分析了火药起动器喷管喉部直径、起动器喷管扩张比、起动器及涡轮喷嘴喉径比等参数对火药起动器和燃气管路工作特性的影响。根据管路的工作特性,提出了一种双喉道燃气管路的设计方法。 |

| Abstract: | The capability of the start system is important to liquid rocket engines. Aimed at the turbopump-fed liquid rocket engine, started by Solid Start Cartridge （SSC） , performance of the powder gas pipeline with two throats behind the Solid Start Cartridge is studied in this paper. The numerical model of the powder gas pipeline is established to analyze the effect of the diameter of the solid start cartridge nozzle throat, the divergent ratio of the cartridge nozzle and the ratio of the cartridge nozzle throat to the turbine injector element throat. One way is offered to design this kind of pipelines |
| Keywords: | liquid rocket engine start-up system powder gas pipeline with two throats start-up characteristic simulation |
