Progress Report on Development of a Cu-8 Cr-4 Nb Alloy Database for the Reusable Launch Vehicle (RLV)

摘要

The next generation of Reusable Launch Vehicle (RLV) will utilize regeneratively cooled combustion chamber liners in the engines. The current design calls for using a new Cu-8 at. percent Cr-4 at. percent Nb (Cu-8 Cr-4 Nb) alloy for the liners. Work is ongoing to characterize the thermophysical and mechanical properties of the alloy from-253 to 800 deg C, the temperature range to which the alloy will be subjected during service.
