Re-entry vehicle is the part of space craft that is designed to return through earth is atmosphere. It is built to intense heating during high velocity flight through the atmosphere and to protect the crew and/or instrument until it bring them safety to earth. Aero thermodynamic analysis plays a critical role in designing a vehicle for hypersonic flight. Accurate information on the vehicle aerodynamic along the descent trajectory allows one to understand the capsule performance and therefore increase the payload and reduce the heat shield thickness on the vehicle. one of the main concerns of the aerodynamics of planetary entry is the heating rate and damage that this may cause to the vehicle at hypersonic flight speed during the reentry large fraction of the kinetic energy will be converted into heat that effect the vehicle.
In this project we do shock wave, thermal and structural analysis of re-entry vehicle by using CFD software and by comparing the analysis results with the result of aerogel material and we conclude the application of aerogel to withstand the aerodynamic heating for future heat ablative materials in re-entry vehicle.
