Abstract
The detection performance of an ablation sensor, named Ablation Sensor Unit (ASU), which can measure surface recession, thermal decomposition of resin, and temperature of an ablative heat shield material, is demonstrated. A test specimen with embedded ASU is heated using a JAXA 750 kW arcjet wind tunnel facility under one operational condition. The amount of surface recession and char depth and temperature obtained by ASU are compared with the posttest measured values for the recovered test specimen and the surface temperature obtained by a two-color thermometry. The comparison shows that ASU is promising for a simultaneous and an in situ measurement of the ablation phenomena for the ablative heat shield.
