| Outline of Final Research Achievements |
An ablation sensor is developed, in which a variable resistive circuit and an optical fiber measurement technique are implemented into a single unit. The developed ablation sensor is miniaturized to be applicable to a flight measurement. In order to examine the operational characteristics of the ablation sensor, the ablation sensor is tested with an arcjet wind tunnel by being embedded into a low density ablative test specimen. The results show that fair agreement is obtained between the sensor output and the measured data for the recession and char depth of the tested specimen, demonstrating that the developed sensor can simultaneously measure the receded and charred fronts of the ablative heat shield during heating.
