Ablative Cooling
Ablative cooling is a method of protecting spacecraft or rocket parts from extreme heat by using a sacrificial material that slowly erodes or vaporizes, carrying heat away from the structure. This process absorbs thermal energy as the material changes phase, preventing damage to critical components.
TECHNICAL DEFINITION
Ablative cooling is a passive thermal protection system (TPS) utilized in aerospace propulsion systems like rocket nozzles, re-entry vehicles, and missile nose cones, where a sacrificial ablative material undergoes an endothermic phase change (e.g., sublimation, vaporization, pyrolysis) when exposed to extreme aerodynamic heating or hot exhaust gases, absorbing and dissipating thermal energy to protect underlying structures.
BACKGROUND
Skyroot Aerospace Private Limited is a private Indian aerospace manufacturer and commercial launch service provider headquartered in Hyderabad, Telangana. The company was founded by former engineers and scientists from ISRO.
