The invention relates to a thermal examination test system for a thermal protection structure of a hypersonic aircraft. The test system comprises a closed test cabin, a fuel storage tank, a gas inlet pipeline and a fuel gas generator, and the fuel gas generator conveys high-temperature fuel gas into the closed test cabin through a fuel gas pipeline; the closed test cabin comprises a cabin body, a plurality of straight flame burners and a plurality of observation window assemblies; the plurality of straight flame burners are arranged in the cabin body and are connected with an external gas pipeline, and the plurality of observation window assemblies are respectively arranged on the cabin body. Natural gas is used as a heating source, high-temperature gas generated by the direct flame burner is used for heating an aviation equipment test piece in the whole field, and the highest heating temperature can reach 1500K. The test system has the advantages of low test cost, large test structure size, wide applicability, short test preparation period and the like; and the requirements of high-frequency and low-cost thermal examination tests on aerospace crafts can be met.

    本发明涉及一种高超声速飞行器热防护结构的热考核试验系统。所述的试验系统包括密闭试验舱、燃料储藏罐、进气管道和燃气发生器,所述的燃气发生器通过燃气管道将高温燃气输送至密闭试验舱内;所述的密闭试验舱包括舱体、多个直焰烧嘴和多个观察窗组件;所述的多个直焰烧嘴设置在舱体内并连接外部燃气管道,所述的多个观察窗组件分别设置在舱体上。本发明以天然气为加热热源,利用直焰烧嘴产生的高温气体对航空器材试验件进行全场加热,最高加热温度可达1500K,本试验系统具有试验成本低、试验结构尺寸大、适用性广、试验准备周期短等优点,可满足对航天飞行器高频次、低成本热考核试验的需要。
