Abstract
A new scriptedMonte Carlo analysis software tool has been developed for use with the fully implicit ablation and thermal response program thermal-protection-system-sizing code. This paper describes the new software tool and gives examples of its increased utility and useful insights onmany aeroshell heatshield design considerations, such as maximum bond line temperature, recession, isotherm depth, surface temperature, and char depth. Finally, results are presented that illustrate the effect of uncertainties in key parameters that were used in the Mars Science Laboratory aeroshell thermal protection system design. The parameters having the greatest influence on bond line temperature dispersion for theMars Science Laboratory backshell are virginmaterial thermal density (34%), initial material temperature (20%), virgin material conductivity (17%), and char density (13%).
