Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment. Further, the beam structure forms a portion of the internal support structure of the first blade segment. Moreover, the beam structure is formed, at least in part, of a first portion constructed of a first composite material and a second portion constructed of a different, second composite material. Further, the first and second portions are connected together via a scarf joint. In addition, the scarf joint includes a different, third composite material arranged between the first and second composite materials. | 2022-01-13 |
20220010767 | WIND TURBINE JOINTED ROTOR BLADE HAVING A HOLLOW CHORD-WISE EXTENDING PIN - 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 includes at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment via a receiving section. The rotor blade also includes at least one chord-wise extending pin positioned through the chord-wise joint so as to secure the first and second blade segments together. Further, the chord-wise extending pin includes a hollow cross-section that extends from a trailing edge end to a leading edge end thereof. | 2022-01-13 |
20220010768 | BEAM STRUCTURE FOR A SEGMENTED ROTOR BLADE HAVING A TRANSITIONING SHAPE - A spar assembly for a rotor blade including a beam structure extending between a closed first end and a second end configured for coupling within a shell of the rotor blade. The beam structure includes a contacting portion extending in a span-wise direction from the second end, a joint portion extending in the span-wise direction from the first end toward the contacting portion, and a transition region between the contacting portion and the joint portion. The contacting portion includes one or more contoured surfaces oriented toward at least one of an internal surface of a pressure or suction side of the rotor blade and configured to follow a contour of one of the pressure or suction side of the rotor blade. The joint portion includes one or more linear surfaces oriented in the same direction as the contoured surface(s). The transition region transitions the contoured surface(s) to the linear surface(s). | 2022-01-13 |
