摘要
测量超燃冲压发动机内部温度及热流场可以为表征、评估、优化其工作状态与性能提供重要支撑。本文综述了可用于发动机温度及热流测量的接触式(铠装及薄膜式)传感器、非接触式(光电及辐射式)测量技术的研究现状及特点。重点介绍了薄膜式热电偶及热流计的发展趋势以及在高温瞬时测量领域的应用前景。最后,对超燃冲压发动机温度及热流测量技术进行了展望。
The accurate measurement of temperature and heat flux field in scramjet provides strong support for characterization,assessment and optimization of scramjet engine.Measurement methods are reviewed and analyzed,including sheathed and thin film sensors,and photoelectric method and radiation method.Researches of thin film sensors are introduced,and the applications of thin film thermocouple and heat flux sensors in scramjet are pointed out.
