Vibration in the PMEL (Precision Measurement Equipment Laboratory) and Fire Station Buildings during Engine Tests in the T-9 Noise Suppressor System, McConnell AFB Kansas

Pagination or Media Count:
Vibration measurements were collected at the Precision Measurement Equipment Laboratory PMEL and Fire Station buildings during operations of the AF32T-9 Large Turbo Fan Engine, Enclosed Noise Suppressor System T-9 NSS at McConnell AFB KS. The highest vibration levels were measured with an F101 engine operating at afterburner power in the T-9 NSS. The measured floor vibration levels are well below both the limits recommended to prevent adverse health effects and those limits recommended to prevent decrease in proficiency at performing work tasks. The measured floor vibration levels do not even exceed the threshold of perception of the most sensitive individuals to whole body vibration. Measurements did not rule out the possibility of exceeding recommended levels for interference with vibration sensitive calibrations at the PMEL buildings.
