Abstract |
A series of experiments was statistically designed and conducted to determine the effect of environments singularly and in combination upon the performance of a specimen representative of typical aircraft or missile equipment. The test specimen consisted of electronic, mechanical, and hydraulic components assembled in a manner which would produce a measurable deviation from a reproducible norm when subjected to combinations of the following eight environments: (1) high temperature, (2) low temperature, (3) thermal shock, (4) altitude, (5) humidity, (6) vibration, (7) mechanical shock, and (8) sustained acceleration. The experiments consisted of 8 single-environment tests, 21 combinations of 2 environments, 25 combinations of 3 environments, and 4 combinations of 4 environments. In general, the results of the experiments indicated that the response or deviation from the norm of the test specimen when subjected to multiple environments was greater than the sum of the environments when taken independently.
