摘要
利用双波长方法,对发动机工况下不同类型的固体推进剂的燃烧温度进行了测试,获得了高能推进剂的燃烧温度及其随压强的变化。结果表明,双波长方法作为非接触测试手段,可用于超高温测量,并且具有很高的时间分辨率(ns级),获得的推进剂燃烧温度随压强的变化,与理论预示结果相比,吻合较好。双波长测温方法在固体推进剂特别是高能推进剂在恶劣燃烧环境下燃烧温度的实时动态测量中展示了很好的应用前景。
A two-wavelength optical method used for the combustion temperature measurement of solid propellant under SRM operating condition was developed and verified.The temperament measurement results of several solid propellants demonstrated the validation of the method in high temperature measurement.The variation of the combustion temperature with combustion chamber pressure was obtained,and the result was basically accordant with theoretical heating calculation results.The test results indicate that the two-wavelength optical method shows promising prospect as a real-time and fast response means to dynamically measure the high combustion temperature of solid propellant,especially the high energy solid propellant in harsh combustion environment.
