  • Verification of Ablation Detection Method in an Unsteady Heating Environment

説明

<p>Ablation detection accuracy of an ablation sensor named Ablation Sensor Unit (ASU), which can measure surface recession, thermal decomposition, and temperature of an ablative heat shield material, is examined under time-varying heating condition. A test specimen with embedded ASU is heated in an atmospheric entry heating simulation system using Oxy-Hydrogen torch recently developed by the present authors. Time-resolved ASU data for surface recession and the charred front is reported for a time-dependent heating condition. The validity of the detection accuracy of the ASU data is qualitatively discussed by comparing it with the time history of the surface temperature data.</p>
