Blunted-Cone Heat Shields of Atmospheric Entry Vehicles

Abstract

Atmospheric entry of a spacecraft generates extreme temperatures (>5000 K) due to its high speed and the resulting aerodynamic heating. Such extreme conditions require special design considerations to ensure safe passage of the craft through the atmosphere. One commonly employed technique is to use a heat shield. This device protects the craft from the high temperatures generated and also provides the necessary aerodynamic braking and stability for controlled entry through the atmosphere.
