Vibration and Acoustic Environment of OH-6A Helicopter Configured with and Using the XM-27 Armament System

Vibration and acoustic measurements were made on an OH-6A helicopter equipped with a XM-27 armament system to determine the vibration and acoustic environment throughout the vehicle. Tape recordings from 60 accelerometers and 11 microphones were made during all flight conditions including gunfire. S...

Zusammenfassung:	Vibration and acoustic measurements were made on an OH-6A helicopter equipped with a XM-27 armament system to determine the vibration and acoustic environment throughout the vehicle. Tape recordings from 60 accelerometers and 11 microphones were made during all flight conditions including gunfire. Spectrum analyses were performed to obtain vibratory double amplitude, acceleration power spectral density, and sound pressure level, versus frequency. Amplitude probability density plots are included. Measured vibration and acoustic data are compared with military standards and specification requirements.
