GH_2/GO_2涡流冷却透明燃烧室方案设计及试验研究

涡流冷却是一种新型的推力室冷却技术,采用该技术可以简化推力室结构、降低成本,并提高系统可靠性。本文在综合国外研究成果的基础上,对涡流冷却技术进行了理论分析,设计出推力室结构,采用石英玻璃加工燃烧室圆柱段部分,并用高速摄影仪记录了燃烧室内的火焰图像。研究表明,涡流冷却透明燃烧室方案是可行的,燃烧稳定段燃烧区域占燃烧室的55%～60%。

Design and experiment research of GH2/GO2 vortex-cooling transparent combustion chamber

Vortex-cooling is a new thrust chamber cooling method. This technology can simplify the thrust chamber structure, reduce cost and increase system reliability. Based on the research findings of foreign countries, the vortex-cooling technology was analyzed theoretically, the structure of thrust chamber was designed, quartz glass was adopted to make the cylindrical part of the chamber, and the flame images were recorded by a high-speed camera. The results show that the design scheme of GH2/GO2 vortex-cooling transparent combustion chamber is feasible. The combustion zone occupied 55%-60% of the combustion chamber designed with this scheme in the stable period of combustion.
