Aluminum Alloys for Cryogenic Tanks: Oxygen Compatibility. Volume 1
Abstract
In Part I of this program, Al-Li alloys 8090-T3 and 2090-T81 and Al alloy 2219 (tempers T851, T37) were tested for compatibility with liquid oxygen using pressurized mechanical-impact apparatuses at two NASA laboratories, Marshall Space Flight Center (MSFC) and White Sands Test Facility (WSTF). Specimens and data from tests at Santa Susana Field Laboratory (SSFL), Rocketdyne, on alloy 2090-T81 were supplied by ALCOA. Pressurized mechanical- impact data on alloy WL049-T351 were produced by WSTF. In addition, WSTF conducted open-cup mechanical-impact and promoted-combustion tests on all alloys. Reactions occurred in some specimens of all alloys during pressurized mechanical-impact tests at MSFC. There were no reactions during similar tests at WSTF and SSFL. The reactions at MSFC are not attributed to specimen contamination. This interim report analyzes the ignitions found in the MSFG pressurized mechanical-impact tests, compares the results and test methodologies of both MSFC and WSTF facilities (since each laboratory is producing test data that are apparently divergent), and addresses the current test standard document NASA NHB 8060.1B as it pertains to this study.
