Described are a gas turbine engine fan blade platform, related rotor assembly and gas turbine engine, as well as a method of assembling the same. The platform has a forward portion proximal to an axis of rotation, an aft portion, and a transition portion between the forward and aft portions. The forward portion has a forward interface surface facing axially forward, the aft portion has an aft interface surface facing radially outward, and the transition portion has at least one mounting feature. For the method of assembly, an aft support is installed on a fan disk and booster spool assembly. A plurality of fan blades are installed into a fan disk, followed by installing a fan platform between adjacent blades and securing the mounting features to the disk, thereby filling the annulus of the fan disk. Finally, a forward support is installed on the fan disk.

A rotor blade assembly for a wind turbine includes a rotor blade having a pressure side member, a suction side member, a leading edge, and a trailing edge extending between a tip and a root. An electrically conductive band extends longitudinally on either or both of the pressure side member and suction side member along the trailing edge. A plurality of electrically conductive noise reduction features extend from the trailing edge and are configured as individual lightning strike receptors. The noise reduction features are configured in conductive communication with the conductive band.

A spar assembly for a rotor blade of a wind turbine is disclosed. The spar assembly may generally include a first spar cap and a second spar cap spaced apart from the first spar cap such that a cross-sectional area is defined directly between the first and second spar caps. Additionally, the spar assembly may include a web having a first end disposed adjacent to the first spar cap and a second end disposed adjacent to the second spar cap. The web may be configured such that at least a portion of an inner surface of the web is disposed outside of the cross-sectional area.

A wind turbine blade having two shell portions bonded together to form a wind turbine blade having an interior space having an axial length. A web disposed between the shell portions in the interior space and extending substantially the axial length thereof. Lightning receptors are disposed on the shell portions and a conductor is disposed in the interior space. The conductor is configured to contact the lightning receptors. One shell portion of the two shell portions has a removable section, e.g. a plug, receptor or panel, to provide access to the opposite conductor. A cable mounted on the web is configured to extend substantially the axial length of the wind turbine blade and is in electrical contact with the conductor.

A blade for the use in the generation of power has a leading edge and a trailing edge. A first shell portion of the blade extends from the leading edge to the trailing edge. A second shell portion of the blade also extends from the leading edge to the trailing edge. A root portion of the blade is positioned proximate the wind turbine and a tip portion which extends from the root portion away from the wind turbine. A trailing edge insert is positioned between the first shell portion and the second shell portion proximate the root portion. The trailing edge insert has a surface which extends between and separates the first shell portion from the second shell portion at the trailing edge, such that the insert provides a high lift profile for increased blade efficiency.
