摘要

已经开发了一种测定大气层再入过程中热屏蔽升华(炭)和表面衰退(烧蚀)的技术。嵌入隔热层材料中的放射性“线”源以与隔热层相同的速率升华和烧蚀。源活度的减少由小型化核计数器监测。准确度可超过90%。该技术提供了连续的炭烧率和消融率指示。

Heat-Shield Ablation and Sublimation Determinations through Radioisotope Techniques

A technique has been developed for the determination of heat-shield sublimation (char) and surface recession (ablation) during an atmospheric reentry. A radioactive "line" source embedded in the heat-shield material sublimes and ablates at the same rate as the heat shield. Decreases in source activity are monitored by miniaturized nuclear counters. Accuracies exceeding 90 percent are obtainable. The technique provides a continuous indication of char and ablation rates.
