LONG-LIFE ASSURANCE STUDIES OF EEE PARTS AND PACKAGING LONG-LIFE ASSURANCE STUDY FOR MANNED SPACECRAFT LONG-LIFE HARDWARE VOLUME II

摘要

The objectives of this Long-Life Assurance Study were to develop and document the engineering approach necessary to assure that hardware selected for manned spacecraft is based on the experience gained from the manned and unmanned space programs conducted to date, and will meet the following long-life goal:A five-year operational lifetime goal without maintenance is considered the minimum long-life goal with a 10-year desired operational life time.nA detailed engineering study was conducted of the design;application;failure mechanisms;manufacturing processes and controls;screen and burn-in techniques;functional, qualification and life testing;and other factors affecting the hardware items under study. The hardware items investigated are listed in Table 1. In addition, special studies of a more general nature, not oriented towards specific parts or hardware items, were also accomplished. The special studies performed are listed in Table 2.
