国外典型大推力氢氧发动机推力室技术方案综述

Review on Technical Schemes of Foreign Large LOX/LH_2 Thrust Chamber

为了获取大推力氢氧发动机推力室设计的相关准则和经验,通过对比分析国外典型大推力氢氧发动机推力室的技术方案,总结了喷注器、主燃烧室和喷管延伸段等组合件关键设计参数和结构方案的选择规律,以及工艺方法和材料应用的发展趋势,可为中国未来200 t级大推力氢氧发动机推力室方案的确定提供相应的设计参考。

In order to obtain design criterion and practical experience, the current technology of foreign large LOX/LH2 thrust chamber is reviewed. The laws of key design and structure parameters selection of injectors, combustion chamber and nozzle extension are summarized as well as the future development trend of production technology and material application, which gives the design reference to China future 200 t large LOX/LH2 thrust chamber.
