介绍了中国航天空气动力技术研究院辐射加热设备的开发及运用情况。设备包括0-150 kW的石英灯加热器,试验舱,真空系统以及控制系统。在辐射加热设备上对低密度隔热材料在不同低压下的隔热性能进行了研究,所用模型横截面积为100 mm×100 mm,最长运行时间2 000 s,低密度隔热材料的表面温度高达1 000 K,试验舱最低压力为10 Pa. The development and application of radiant heating equipment of China Aerospace Aerodynamics Research Institute are introduced. Equipment includes 0-150 kW quartz lamp heater, test chamber, vacuum system and control system. The heat insulation performance of low-density insulation materials under different low pressures was studied on radiant heating equipment. The cross-sectional area of ​​the model used was 100 mm × 100 mm and the maximum operating time was 2 000 s. The surface of the low-density insulation Temperature up to 1000 K, the lowest pressure in the test chamber is 10 Pa.
