AbstractThe innovation addressed in this proposal is Sprayable Thermal Insulation for Cryogenic Tanks, or STICT. This novel system could be applied in either an automated or manual spraying process, with much less sensitivity to process chemistry and environmental parameters than cur-rent spray-on foam insulation (SOFI) products like BX-265, while providing better insulation performance. The resulting material would form an aerodynamically smooth, uniform coating with better cohesion and significantly lower thermal conductivity. This would allow thinner layers of insulation which, when combined with greater material strain-to-failure, will eliminate the generation of in-flight debris. In this way, the proposed CryoGel insulation can render future space transportation systems safer and more reliable.
