Multidimensional material response simulation of a full-scale tiled ablative heatshield

The Mars Science Laboratory (MSL) was protected during Mars atmospheric entry by a 4.5 meter diameter ablative heatshield, assembled in 113 tiles. The heatshield tiles were made of NASA’s flagship porous ablative material, the Phenolic Impregnated Carbon Ablator (PICA). This study provides a detailed three-dimensional heat and mass transfer analysis of the full-scale MSL tiled heatshield.
