ABSTRACT:
A vibration-isolatator utilizes a relatively small-diameter tuning port or passage and associated reduction in component size. In the illustrative embodiment described herein, a passive isolator is provided which includes a tuning passage or port which has a diameter which is approximately one-half the diameter of the prior-art isolators. The reduced radial dimension of the tuning passage of the isolator results in a remarkable decrease in its size and weight, thus increasing the efficiency of operation of the aircraft.
