- 摘要:
- 为了模拟飞行状态下进入超燃冲压发动机燃烧室的高焓空气，在地面模拟试验中需要对空气加热，可再生蓄热式加热器是一种能提供相对纯净高焓空气的试验设备。介绍了蓄热式加热器的工作原理与特点，分析了关键技术。结果表明，蓄热式加热器具有加热空气总温高、流量大和相对纯净的优点，是我国超燃冲压发动机地面试验的发展趋势，但蓄热阵材料、加热器结构、超高温阀和大范围调节预热燃烧器等是关键技术，有待进一步研究和攻关。
- Abstract:
- In order to simulate the air temperature in the combustion chamber of scramjet, the air used by the ground simulation test should be heated. This paper presents the design specification of a cored brick storage heater, which can supply high temperature clean air to meet the demands of supersonic combustion experiments. Key technologies of developing thermal energy storage heater are analyzed. The results show that with proper material and structural design, it is possible to use a thermal energy storage heater to obtain clean air flow of Mach 6. However, real performance of materials, the heater structure, the ultra high-temperature valve and gas generator still need to be studied to solve the remaining issues in the thermal energy storage heater.
