Spacecraft ablation

In spacecraft design, ablation is used to both cool and protect mechanical parts and/or payloads that would otherwise be damaged by extremely high temperatures. Two principal applications are heat shields for spacecraft entering a planetary atmosphere from space and cooling of rocket engine nozzles. Examples include the Apollo Command Module that protected astronauts from the heat of atmospheric reentry and the Kestrel second stage rocket engine designed for exclusive use i… Web1. okt 2024 · Large-scale spacecraft in orbit faces the problems of deorbiting at the end of life and disintegrates due to tremendous aerodynamic/thermal environment during …
