Tail rotor shaft vibration measurement tests were conducted on a production UH-1H helicopter to define tail rotor shaft vibration characteristics during ground runs. Testing was performed by the United States Army Aviation Engineering Flight Activity at Edwards Air Force Base, California, between 19 March and 4 April 1974. The testing consisted of 11 ground runs totaling one productive test hour. Vibration data were recorded from 7 accelerometer locations for 11 tail rotor shaft configurations, and narrow band spectral analyses were performed on the vibration data.
