【摘要】 本文分析了几种常见热流传感器的原理和应用场合,并通过爆轰驱动激波管作为气动加热模拟实验设备,用自己研制的同轴热电偶测量出模型驻点区的热流值,采用数值积分作为温度-热流转换的数据处理手段,为临近空间飞行器驻点区热流率测量提供实验依据。更多还原

【Abstract】 By analyzing the principles and using occasions of common heat-flux sensors,self-made coaxial thermocouple heat-flux sensors are used to measure the heat-flux values in stagnation zone in this paper.The detonation-driven shock tube is applied as aerodynamic heating equipment in this simulation experiment,and the temperature-heat conversion data is processed by numerical integration.Finally,an experimental result of heat-flux measurement at stagnation point is provided for near space aircraft.更多还原
