Motorized aircraft and other mechanical constructs subject to a force vibrate at resonant frequencies, causing parts degradation, unpleasant sensations for occupants, unwanted noise, and other undesirable effects. Tuned vibration absorbers that mitigate these effects typically counteract vibrations at specific frequencies traveling in specific directions at specific locations within a given structure and are not adjustable. The present disclosure details a disk-shaped tuned vibration absorber that may be tuned on-the-spot within a structural mount such that the frequency at which the disk resonates may be varied and such that the working direction of the disk may be varied. The direction of vibration absorption of the disk may be altered by reconfiguring the disk within its mount, and the resonance of the disk may be altered by rotating an inner component of the disk. The inner component comprises a mass and an elastomer of circumferentially varying stiffness.
