Vibration and temperature measurement tests were conducted on a production model CH-47C helicopter to define the vibration and temperature environment for the instruments, avionics, pilot station, and selected component parts for representative flight conditions. Testing was performed by the United States Army Aviation Engineering Flight Activity at Edwards Air Force Base, California, between 18 July 1974 and 20 September 1974. The testing consisted of 16 flights totaling 19.3 productive test hours. Vibration data were recorded from 63 accelerometer locations for 55 flight conditions and narrow band spectral analyses were performed on the vibration data. The results of the spectral analyses were summarized by use of statistical methods.
