Abstract

The performance evaluation of a single-body typed TDLAS sensor was experimentally conducted using a scramjet ground test facility. The scramjet ground test facility includes model scramjet isolator and combustor. The model scramjet isolator of the test facility can simulate the air flow condition of total temperature of 1,220 K, total pressure of 862 kPa, and Mach number of 2.43 which are representative of the internal flow condition of the scramjet isolator. To evaluate the performance of the single-body typed TDLAS sensor, the TDLAS sensor was flush-mounted on the model scramjet isolator wall of the test facility during the ground test, and the structural integrity and operability of the TDLAS sensor were analyzed based on the robustness of the TDLAS’s components, the stability of signal acquisition, and an accuracy of the measured data. The experimental ground test results demonstrated that the single-body typed TDLAS sensor in this study can withstand and operate well under the harsh mechanical and thermal environments of the model scramjet isolator.

基于超燃冲压发动机地面试验装置的单体TDLAS传感器试验性能评价

利用超燃冲压发动机地面试验装置对单体型TDLAS传感器进行了性能评估。超燃冲压发动机地面试验装置包括超燃冲压发动机模型隔离器和燃烧室。试验装置的模型超燃冲压发动机隔离器可以模拟总温度1220 K、总压862 kPa、马赫数2.43的气流状态，这些气流状态代表了超燃冲压发动机隔离器内部的流动状态。为评价单体型TDLAS传感器的性能，在地面试验过程中，将TDLAS传感器平装在试验设施的模型超燃冲压发动机隔离壁上，从TDLAS组件的鲁棒性、信号采集的稳定性和测量数据的准确性等方面分析了TDLAS传感器的结构完整性和可操作性。地面试验结果表明，所研制的单机型TDLAS传感器能够很好地承受模型超燃冲压发动机隔离器恶劣的力学和热环境，并能正常工作。
