Thermal Protection Systems - NASA
The Space Shuttle design presented many Thermal insulationchallenges. The system not only had to perform well, it had to integratewith other subsystems. The Orbiter s surfaces were exposed toexceedingly high temperatures and needed reusable, lightweight,low-cost Thermal Protection . The vehicle also required low vulnerabilityto orbital debris and minimal Thermal conductivity. NASA decided tobond the Orbiter s Thermal Protection directly to its aluminum skin,which presented an additional challenge. The External Tank required insulation to maintain the cryogenic fuels,liquid hydrogen, and liquid oxygen as well as to provide additionalstructural integrity through launch and after release from the challenge and solutions that NASA discovered through tests andflight experience represent innovations that will carry into the nextgeneration of space InnovationsThermalProtectionSystemsIntro ductionGail ChaplineOrbiter Thermal Protection SystemAlvaro RodriguezCooper SnappGeminesse DorseyMichael FowlerBen Gr
Protection System tile design, each tile experienced stresses induced by the following combined sources: n Substrate or structure out-of-plane displacement n Aerodynamic loads on the tile n Tile accelerations due to vibration and acoustics n Mismatch between tile and structure at installation n Thermal gradients in the tile n Residual stress ...
