Abstract: A hydraulic machine includes a first member (1) having a first structure (2) for a hydraulic medium opening in a first interface surface (3) and a second member having a second structure for the hydraulic medium opening in a second interface surface is described, the first interface surface (3) being in contact with the second interface surface, wherein at least one of the members (1) is provided with a support element (6) surrounding the member (1). Such a machine should have a good efficiency. To this end the support element (6) has a strength varying in circumferential direction around the member (1) and/or in thickness direction in a middle region of the member (1).

Abstract: A method of assembling a rotor blade for use with a wind turbine. The method includes coupling a first sparcap to at least one first panel wall to form a first blade section, wherein the first sparcap has a first chordwise width. A second sparcap is coupled to at least one second panel wall to form a second blade section. The second sparcap has a second chordwise width that is larger than the first chordwise width. The first blade section is coupled to the second blade section to form the rotor blade.

Abstract: A rotor blade for a wind turbine is disclosed. The rotor blade includes a flange section configured to connect the rotor blade to a rotor hub; and an airfoil section extending outward from the flange section. The flange section is comprised of a carbon reinforced polymer.
