| 英文摘要 | In this study, the performance of ablative material-filled sandwich structures with truss cores under laser irra-diation is experimentally analyzed in a hypersonic wind tunnel. As a comparison, we investigated the responses of a monolithic high-temperature alloy plate, unfilled sandwich panel, and thermal insulating material-filled sandwich panel. Failure times and ablation morphologies are assessed using a high-speed camera, while tem-perature histories are obtained using a colorimetric pyrometer. Experimental results show that, when subjected to a transverse hypersonic airflow, the laser resistance of the ablative material-filled sandwich structures is substantially better than that of other structures. Compared to a static environment, failure times of the sandwich structures in the hypersonic airflow are reduced due to the mechanical erosion effect. The detailed action mechanisms of the ablative material-filled sandwich structures are revealed by numerical modeling and the characterization of the ablation morphology. |
