Abstract: A method for manufacturing a rotor blade root assembly includes placing outer skin layer(s) onto a blade mold and arranging a root plate with a plurality of through holes adjacent to an end face of the blade mold. The method also includes placing a plurality of root inserts atop the outer skin layer(s) and abutting against the root plate, with each of the root inserts defining a fastener hole. The method also includes inserting a root fastener into each of the aligned through holes and longitudinal fastener holes. Moreover, the method includes placing inner skin layer(s) atop the root inserts. Further, the root plate may include at least one fluid hole configured therethrough to provide a non-gas tight root plate. Alternatively, at least one seal may be arranged between the root plate and the blade mold that forms a non-gas tight connection with either or both of the root plate or the blade mold during a vacuum infusion process. Thus, the method includes securing the outer skin layer(s), the root inserts, the inner skin layer(s), and the root fasteners together to form the root assembly via the vacuum infusion process.

Abstract: A method for manufacturing a structural component of a blade segment for a rotor blade includes providing a mold of the structural component having an outer wall that defines an outer surface of the structural component. The method also includes laying up one or more fiber layers in the mold so as to at least partially cover the outer wall. As such, the fiber layer(s) form the outer surface of the structural component. Further, the method includes providing one or more metal mesh layers having one or more ends. Moreover, the method includes providing a cover material to the end(s) of the metal mesh layer(s). In addition, the method includes placing the metal mesh layer(s) with the covered end(s) atop the fiber layer(s). Thus, the method includes infusing the fiber layer(s) and the metal mesh layer(s) together via a resin material so as to form the structural component.

Abstract: A method for manufacturing a structural component of a blade segment for a segmented rotor blade of a wind turbine includes providing a mold of the structural component. The mold has an outer wall that defines an outer surface of the structural component. The method also includes securing at least one tooling pin to the outer wall for defining a pin joint slot in the structural component. Further, the method includes laying up one or more outer fiber layers in the mold so as to at least partially cover the outer wall. The outer fiber layer(s) has at least one hole that receives the tooling pin(s). As such, the outer fiber layer(s) form the outer surface of the structural component. Moreover, the method includes placing one or more structural features atop the outer fiber layer(s) in the mold. In addition, the method includes infusing the outer fiber layer(s) and the structural feature(s) together via a resin material so as to form the structural component.

Abstract: A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint line. Each of the first and second blade segments includes opposite spar caps. The first and second blade segments are connected at the chord-wise joint line by internal joint structure, wherein the joint structure is bonded to the opposite spar caps in at least the second blade segment. The spar caps in the second blade segment have a first section with a first chord-wise width that is unbonded to the joint structure and a second section with a second chord-wise width that is bonded to the joint structure. The second chord-wise width is greater than the first chord-wise width.

Abstract: A rotor blade includes first and second blade segments extending in opposite directions from a chord-wise joint. The first blade segment includes a beam structure that connects with the second blade segment via a receiving section. A chord-wise gap exists between an edge of the beam structure and an edge of the receiving section. The beam structure defines a first pin joint slot, whereas the receiving section defines a second pin joint slot that aligns with the first pin joint slot. First and second bushings are arranged in first ends of the first and second pin joint slots, each having a flange extending within the chord-wise gap. As such, the flanges abut against each other within the chord-wise gap so as to fill the chord-wise gap with a predetermined defined gap or interference. Further, a chord-wise extending pin is positioned through the bushings so as to secure the first and second blade segments together.

Abstract: A rotor blade for a wind turbine including a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments include one or more shell members and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending between a receiving end and a second end. The internal support structure of the second blade segment includes a receiving section that receives the receiving end of the beam structure of the first blade segment. The rotor blade further includes one or more connection locations where the first and second blade segments are secured together. Moreover, when the beam structure is received within the receiving section, a gap including a varying thickness is defined and maintained between the beam structure and the receiving section in a span-wise direction of the rotor blade.

Abstract: A rotor blade for a wind turbine includes first and second blade segments extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending lengthwise, whereas the internal support structure of the second blade segment includes a receiving section that receives the beam structure of the first blade segment. Further, the rotor blade includes at least one chord-wise extending pin positioned through the beam structure and the receiving section at the chord-wise joint so as to secure the first and second blade segments together. The rotor blade includes at least one additional support member that receives a portion of the chord-wise extending pin so as to reduce a chord-wise bending deflection of the chord-wise extending pin at the chord-wise joint.

Abstract: A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments has at least one shell member defining an airfoil surface and an internal support structure. The first blade segment defines a first pre-bend in a flap-wise direction. The second blade segment defines a different, second pre-bend in the flap-wise direction. Further, the first pre-bend is greater than the second pre-bend. In addition, the first and second pre-bends provide an overall pre-bend in the flap-wise direction away from a tower of the wind turbine that allows for a predetermined deflection of the rotor blade towards the tower.

Abstract: A system for operating a combustor includes a sensor that measures an operating parameter associated with the combustor and generates a signal reflective of the operating parameter. The operating parameter is reflective of an ash deposition rate or an accumulated ash buildup. A controller receives the signal, compares the signal to a predetermined limit, and generates a control signal. A method for operating a combustor includes operating the combustor at a first power level that produces a first temperature that is less than or equal to a first predetermined temperature and creating a layer of ash. The method further includes measuring an operating parameter reflective of an ash deposition rate or an accumulated ash buildup, comparing the operating parameter to a limit, and operating the combustor at a second power level that produces a second temperature that is greater than or equal to the first predetermined temperature.
