ABSTRACT:
The present invention is a damper assembly included in a strut on the front frame for a jet propulsion engine. The damper assembly is disposed within the strut for damping vibration of the strut as a result of air stream pressure pulses from first stage fan blades causing strut excitation when the fan blades are operating at least at transonic speeds.
