The word ablation is derived from the suppletive past particle of the Latin auferre, which means to remove. It was originally used in the geologic sense to describe the combined, predominantly thermal, processes by which a glacier wastes. The present use of the word maintains the thermal aspect and describes the absorption, dissipation, and blockage of heat associated with high speed entry into the atmosphere. Thus ablative, thermal protection materials are used to protect vehicles from damage during atmospheric reentry. The need for these materials was first realized during the development of operational ballistic missiles in Pennemunde, Germany, when a large percentage of V-2s failed to reach their targets because of missile skin disintegration caused by aerodynamic heating (1). Ablative materials are also used to protect rocket nozzles and ship hulls from propellant gas erosion, as protection from laser beams, and to protect land-based structures from high heat environments.

Ablative materials play a strategic role in the aerospace industry. The concept of ablation can be related to a geological term at least 160 years old. It is derived from the suppletive past participle of the Latin “auferre” which means to carry away. Ablative materials are used to produce the thermal protection system (TPS) that protects a body from severe heating encountered during hypersonic flight through a planetary atmosphere. The TPS protects the structure, the aerodynamic surfaces, and the payload of missiles, space vehicles, and probes. Ablative materials are also used to produce passively cooled rocket combustion chambers and nozzles, as well as to protect propulsion devices from very high temperature environments.
