Leveraging Development Investments in Orion<br />
Mars Science Laboratory<br />
• The Crew Exploration Vehicle Advanced Development Program (CEV ADP)<br />
for Orion had invested in the re-development and re-manufacturing of PICA as<br />
a candidate heatshield material, allowing FMI to improve their manufacturing<br />
process<br />
• Orion conducted 125 arcjet tests of PICA<br />
– Tested to more severe environments (heating, pressure, shear)<br />
– Various gap filler designs<br />
– Material characterization ti (material property tests) t performed<br />
– High fidelity response model developed for in-depth thermal and recession<br />
response<br />
• MSL could simplify design because the aeroshell structure t was composite (vs<br />
metallic for Orion) and the CTE agreement was better<br />
– Lower deflections for MSL: direct bonding to structure, and filled gaps were<br />
possible<br />
– Less severe environments thinner TPS for MSL<br />
• MSL tests at lower conditions also informed Orion about PICA’s suitability as a<br />
heatshield hi candidate material, thus both projects benefited<br />
