The invention provides a rotary damper for controlling helicopter motions. The rotary damper includes an outer canister with an inner paddle wheel receiving cavity which receives an inner paddle wheel with upper and lower elastomeric tubular intermediate members between the inner paddle wheel and the outer canister. The canister and inner paddle wheel form neighboring variable volume chambers in liquid communication through liquid damping conduits. A clockwise rotation of the inner paddle wheel about the center of rotation axis relative to the outer canister pumps damper liquid from a second variable volume chamber through a first liquid conduit towards a first variable volume chamber, and a counterclockwise rotation of the paddle wheel relative to the outer canister pumps the damper liquid from the first variable volume chamber through the first liquid conduit towards the second variable volume chamber with the elastomeric tubular intermediate members providing for the relative rotation and containing the damper liquid in the damper.

A frequency-dependent damper for creating a damping force in response to a variable-frequency disturbance includes an outer damper body having an internal cavity, an inner damper body for receiving the variable-frequency disturbance extending into the internal cavity, a first fluid chamber and a second fluid chamber defined inside the internal cavity, a piston separating the first and second fluid chambers, a selected orifice for transferring fluid between the first and second fluid chambers, and a selected spring element arranged serially between the piston and the inner damper body such that the piston can move relative to the inner damper body through deformation of the spring element.

A rotary wing aircraft bearing that provides a constrained relative motion between a first rotary wing aircraft member and a second rotary wing aircraft member. The bearing includes an elastomeric mold bonded laminated bearing stack, the elastomeric mold bonded laminated bearing stack including a plurality of mold bonded alternating layers of nonelastomeric shim member layers and elastomeric shim members layers, the alternating layers having an exterior surface and an interior center distal from the exterior surface. At least one of the elastomeric shim members layers has an interior elastomer region distal from the exterior surface, the interior elastomer region formed an interior cured elastomer composition having at least a first interior optical characteristic ingredient, and an exterior elastomer region encompassing the interior elastomer region, the exterior elastomer region proximate the exterior surface, the exterior elastomer region formed from an exterior cured elastomer composition having at least a second exterior optical characteristic ingredient, the at least second exterior optical characteristic ingredient different than the interior cured elastomer composition first interior optical characteristic ingredient, wherein with an elastomer void crack propagating from the exterior surface inward towards the interior elastomer region and a repeated rotary wing aircraft relative motion between the first rotary wing aircraft member and the second rotary wing aircraft member generates a plurality of interior cured elastomer composition crumbs to be expelled from the elastomer void, the interior cured elastomer composition crumbs optically distinguishable from the exterior cured elastomer composition.
