A centrifugally activated variable damper assembly for a stopped-rotor aircraft is disclosed for adjusting dampening level of teetering motions produced by the rotors during the in-flight conversion process from rotary-wing to fixed-wing flight, or vise versa. The assembly includes a damper valve responsive to centrifugal forces produced by rotational speed of the aircraft rotor. The assembly also includes dampers within the rotor system that operate at variable damping levels in response to centrifugal forces acting upon the damper valve.

[ What is claimed is:] [1.] A centrifugally activated damper assembly, comprising:a. first and second hydraulic dampers, each damper having respective first and second hydraulic chambers; andb. a centrifugal activated valve operatively connecting said respective first and second dampers so as to affect movement of said first and second dampers in response to rotational forces upon said centrifugal activated valve,wherein said centrifugal activated valve is capable of selectively interconnecting each of the hydraulic chambers of said first hydraulic damper with each of the hydraulic chambers of said second hydraulic damper.
