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 was subjected to combinations of high temperature, low temperature, thermal shock, altitude, humidity, vibration, mechanical shock, and sustained acceleration. The results indicated that the response deviation of the specimen when subjected to multiple environments was greater than the sum of the environments when taken independently. The combinations involving altitude, vibration, high and low temperature, and thermal shock produced the greatest interaction while the combination of mechanical shock and sustained acceleration produced the least interaction.
