Abstract: A dual series damper includes a fluid damper portion and a elastomeric damper portion. The fluid damper portion includes a first housing, a first connection member, and a piston coupled to the first connection member. The piston divides an interior of the first housing into a first fluid chamber and a second fluid chamber. The piston has a fluid passage in the piston, the fluid passage being configured to provide fluid communication between the first fluid chamber and the second fluid chamber. The elastomeric damper portion includes a second housing, a second connection member coupled to the second housing, and an elastomer between the first housing and the second housing. When a lead/lag force is introduced to the dual series damper, the fluid damper portion behaves rigidly so that the elastomeric damper portion dampens the lead/lag oscillation.

Abstract: An assembly for providing flexure to a blade of a rotary blade system, the assembly including an upper support plate (22) having an upper curved surface (37) , a lower support plate (24) having a lower curved surface (37) , and a yoke (120) positioned therebetween. At least one of the upper and lower yoke surfaces (37) having a layer of cushioning material (56) positioned thereon and secured thereto. The layer of cushioning material (56) extending along and following the general contour of yoke surface (37) , and the layer of cushioning material (56) directly contacting a support plate (22,24) . Another embodiment is an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate (22) having an upper curved surface (27) , a lower support plate (24) having a lower curved surface (37) , and a yoke (120) positioned therebetween and directly contacting the support plates wherein one of the curved surfaces (37) is a non-circular arc that does not form part of the circumference of a circle.
