| Outline of Final Research Achievements |
In our research, we created a method for remotely measuring ablation that can observe the erosion of thermal protection materials without relying on an embedded sensor. We used a micro-torch heating test method that we had previously developed and added a thermal camera to the setup to capture time-resolved images of the ablation process. We then conducted ablation experiments while measuring using the embedded sensor and our new remote method. This research allowed us to verify the accuracy of detecting ablation using the embedded flight ablation sensor.

| Academic Significance and Societal Importance of the Research Achievements |
従来の大型地上加熱試験風洞では，調査することができなかった非定常空力加熱環境で，飛行環境で使えるアブレーションセンサーの検知精度が調査できるようになったことは，宇宙機カプセルが実飛行する際のアブレーション現象解明につながるとともに，将来の宇宙機カプセルの熱防御材設計にも役立てることが期待できる。
