Abstract : The major components of the self-aligning mountings selected in Phase 1 and the mounting test fixtures were fabricated. Two in-air tests of one mounting concept were completed. One specimen failed after completing 487 cycles at -100 F. The second specimen successfully completed 750 cycles at -100 F but failed after 374 cycles at 1500 F. Concurrent in-air and ultrahigh vacuum testing is scheduled. (Author)
