A Comparitive Analysis of Vibrational Test Requirements and Operational Conditions of Avionics Equipment in a UH-1H Army Helicopter.

Abstract

This paper examines the problem of vibration on instrument and avionics equipment used in a present-day U.S. Army helicopter, and compares the results of this examination to the prescribed vibration testing standards of MIL-STD-810B, 'Environmental Test Methods.' Actual in-flight vibration data of a UH-1H Army helicopter performing various maneuvers are analyzed using power spectrum analysis to determine the vibrational forces present. A comparison of the results of this analysis to the military standard on vibration testing provides information suitable for determining realistic testing methods for avionics equipment in helicopters and for updating the military standard on vibration testing.
