Abstract
In this work, the aerodynamic heating of the SARA Sub-orbital Platform is simulated, considering the air around the external surface in chemical equilibrium when its temperature reaches 2000 K. The simulation is performed coupling the engineering method for aerodynamic heating with the heat conduction in the wall and ablation of the thermal field. Results show that, although the heat convection parameters are strongly influenced by the chemical equilibrium hypothesis, the resulting wall heat flux is the same when the air is considered a perfect gas.
