1. Apparatus for dampening rotor blade vibratory energy which is characterized by a damper disposed beneath the platforms of two adjacent rotor blades and a plate-like seal inwardly of the damper which is radially restrained by the adjacent rotor blades, wherein the spacing of said seal from the damper is sufficiently close such that under centrifugal loading the midportion of the seal deflects to bear against the damper, thereby augmenting the energy dissipation capacity of the damper.
