Ablation
In the context of aerospace engineering, ablation refers to the removal of material from the surface of an object by vaporization, chipping, or other erosive processes. This term is commonly used in the context of space vehicles re-entering the Earth's atmosphere, where the intense heat generated by friction between the vehicle and the atmosphere can cause significant damage. To protect the vehicle and its occupants, engineers design heat shields that intentionally ablate, or wear away, to dissipate the heat. The process of ablation absorbs heat and carries it away from the vehicle, preventing the underlying structure from reaching dangerous temperatures. Ablation is a critical concept in the design of spacecraft and missiles, and understanding it is essential for ensuring the safety and success of space missions.
