Ablation model for silica-phenolic Thermal Protection System(TPS) was developed in this study. Also, computational analysis for such TPS was conducted using the developed model. In order to analyze ablation phenomenon inside the solid, mass and energy balance equations were used as the governing equations. The total recession is modeled to be the sum of recession by reaction and melting. CFD analysis was conducted to predict the minimum radius of TPS for various flight Mach number which can protect the vehicle. This study can aid in preliminary designs of TPS since the minimum radius of TPS can be predicted.
