Performance analysis of advanced spacecraft TPS
Author(s): Pitts, William C.
Abstract: For the Space Shuttle several types of ceramic heat shield materials were developed, both flexible and rigid. Improvements on the materials are continuously evolving. Material properties that have been studied and improved ...
NASA Center: NASA (non Center Specific)
Publication Year: 1987
Added to NTRS: 2005-10-13
Accession Number: 87N21011; Document ID: 19870011578; Report Number: EI87-0403, NAS 1.26:180496, NASA-CR-180496
Performance analysis of advanced spacecraft TPS
Author(s): Pitts, William C.
Abstract: The analysis on the feasibility for using metal hydrides in the thermal protection system of cryogenic tanks in space was based on the heat capacity of ice as the phase change material (PCM). It was found that with ice the ...
