The JRB-52B aircraft was surveyed to determine the vibration environment existing throughout the vehicle under all flight conditions expected in service. Approximately 34,000 data points were obtained from 26 separate locations on the vehicle during 7 test flights. The data obtained were evaluated to determine the adequacy of vibration test requirements for long range bomber equipment contained in MIL-E-5272A. The data indicated that the vibration test requirements of that specification were satisfactory to simulate the actual environment existing on the JRB-52B aircraft.
