PREDICTED VIBRATION AND ACOUSTIC ENVIRONMENTAL STUDY

Abstract

The analysis indicates that the proposed wing skin panels will not experience fatigue failure as a result of acoustic excitation sustained during the 250 hour design life of the aircraft. The vibration environment of the aircraft is expected to be similar to that of other jet aircraft of comparable rated thrust. Based on the anticipated vibration levels and the relatively short design life of the aircraft. components that may be subjected to significant oscillatory load should be investigated for fatigue on an individual basis by the design group involved.
