A rapid-response heat flux gauge has been developed. Platinum resistance bulb of 0.4×0.4 mm area made by vacuum vapor deposition is manufactured by laser trimming on an alumina cylinder of 1.6 mm diameter and 2 mm length. Calibration test for a newly developed heat flux gauge has been conducted and fixed the temperature coefficient and the value of √ρCλ. The response of the heat flux gauge appears to be less than tens of micro seconds and the accuracy is ±10%. The heat flux distribution in the tile gap of an un-manned space shuttle has been measured with high-accuracy and wide range.
