HELICOPTER VIBRATION INDICATOR

Abstract

A requirement exists for a system to detect and alert helicopter pilots to unsafe vibration levels. Five helicopter vibration indicator (HVI) units were evaluated by installing each in one H-21-type helicopter (in lieu of five separate H-21's) in order to obtain comparative data. Results indicated that the helicopter vibration indicators, as designed, were unsuit able for Army helicopter utilization.
