Description
Summary:An investigation was conducted to determine which of several reliability tests provided a most realistic representation of field environments experienced by avionics equipment onboard US Army helicopters. Originally the program was scheduled to test a total of twenty-five AN/ARC-115 radios in groups of five, where each group was subjected to a different reliability test. Flight tests, bench tests, AGREE tests, uniaxial vibration tests, and triaxial vibration tests were the selected environments in which the radios were to be operated under simulated conditions, functional checks performed as required, and any failures noted.
