Embodiment Construction
[0037] Aiming at the existing problems of heat flow sensors in the measurement of heat flow on the surface of hypersonic vehicles, the present invention provides an identification device and design method for heat flow on the surface of hypersonic vehicles, which is suitable for intensive measurement of long-term high heat flow. The technical characteristics of the device are: the heat flow identification device contains sensitive elements made of high thermal conductivity materials (such as copper), which can respond to the aerodynamic heating on the surface of the aircraft relatively quickly; by measuring the temperature change of the sensitive elements inside the heat flow identification device The temperature information is used to invert the heat flow on the surface of the measured position through the heat flow identification method based on inverse problem solving. Since the heat flow identification method in the present invention has no special requirements on the tempe...
