This chapter describes the phenomenon ablation and its mechanisms, as well as its importance in aerospace applications. An illustrative model is analyzed, and the important physical parameters are identified.
Ablation; Ablative material; Heat balance; Integral method; Pyrolysis; Unsteady heat conduction
In aerospace design, ablation is used to both cool and protect mechanical parts that would otherwise be damaged by extremely high temperatures. Examples are heat shields for spacecraft, satellites, and missiles entering a planetary atmosphere from space and cooling of rocket engine nozzles. Basically, ablative material is designed to slowly burn away in a controlled manner, so that heat can be removed ...
