Ablation

Abstract

Two decades of advances in ablation technology are reviewed with particular emphasis on developments of the last eight years. Leveling off of research activities is noted reflecting both the space systems requirements and acceptance of ablation as an established means of thermal protection. Physico- mathematical approaches to analysis of ablation processes are brought out ranging from simplistic heat of ablation concept to the sophisticated analysis of laminar and turbulant flow, non-equilibrium ablation in chemically reacting flow fields including surface reactions and radiative heat transfer. Particular attention is given to the synergistic mechanisms occurring during the ablation process. Examples of nose-tip interaction with aero/thermodynamic environment at the surface and in depth phenomena is given as well as striation phenomena on the afterbody are discussed.
