Title:
A STUDY TO CORRELATE FLIGHT MEASURED HELICOPTER VIBRATION DATA AND PILOT COMMENTS

Abstract:
Lissajous patterns of resultant displacement, velocity, and acceleration are constructed and evaluated to define those characteristics which best correlate with the pertinent pilot comments. A new measure of comfort level, Equivalent Vibration Level V sub og is defined. These quantities are calculated for all Lissajous figures, and resulant acceleration is seen to be the most meaningful parameter. n improvement in the degree of correlation between measured vibration and pilot comment is shown through the use of Veq for the patterns of resultant acceleration, in lieu of the standard vibration criteria.
