Abstract

At the Hypersonic Speeds during Re-entry of a vehicle it experiences Severe Aerodynamic Heating over the surface.it is important to choose the material which have the capability to resists high heating temperatures. For this purpose, Thermal Protective Systems (TPS) are Developed. TPS is the Barrier that protects the body or vehicle during reentry. The material which we are choosing for atmospheric exposed surface area should have high reluctance to Heat and these materials are termed as Ablative Materials. These ablative materials protect the Structure, aerodynamic surfacesand payload of vehicles from heat and damages also helps in cooling the combustion chamber of Rocket engines. Formation of Char over the surface is a criterion of Ablative Material to be chosen. Char is a carbonaceous deposition; Formation of Char over the surface does not allow heat transfer to inside materials. Ablative material must be chosen based on following criteria (i). Resistance to thermal heat. (ii) High char forming capacity (iii) low coefficient of thermal expansion. In order to choose an Ablative Material for the above-mentioned conditions a review had been done.

Key Words

Hypersonic, Aerodynamic, carbonaceous.
