Abstract: A wind turbine rotor blade assembly and associated method include a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. An edge extension panel is attached along either of the leading edge or trailing edge (or along both edges) in a generally span-wise direction from adjacent the root towards the tip. The edge extension panels include a cured and hardened viscous material continuous core formed onto the leading or trailing edge with a contoured generally aerodynamic outer surface.

Abstract: A variable ram for a blowout preventer is disclosed. The variable ram includes a ram block and a ram packer assembly disposed at least in part within the ram block. The ram packer assembly includes a plurality of inserts and a packer member. The plurality of inserts is configured to form an insert array, where the insert array includes a peripheral surface, and where the peripheral surface of the insert array is disposed facing an opening configured to receive a tubular member. The packer member is coupled to at least a portion of the plurality of inserts for providing a unitary structure to the ram packer assembly, where the packer member protrudes from the peripheral surface of the insert array into the opening to define a bore face of the variable ram, and where the packer member includes an elastomeric material.

Abstract: A variable ram packer includes a body including two contact regions. The first contact region includes a region of the body of the packer that includes a first material and a second material, layered on top of one another. The first material has an elastic modulus less than that of the second material. The second contact region includes the second material and a third material, layered on top of one another. The third material has an elastic modulus greater than that of the second material, but less than that of the first material.
