Abstract: A wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint line and connected at the chord-wise joint line by internal joint structure. Opposite spar caps in the first blade segment include a longitudinally extending center section having a constant transverse width up to the chord-wise joint line. Wing members are disposed against opposite longitudinal sides of the center section, each wing member having a head section with a constant transverse width and a flared tail section having a decreasing transverse width, the head section aligned with an end of the center section at the chord-wise joint line. The center section is formed from a first material having a first rigidity and the wing members are formed at least partially from a second material having a second lesser rigidity such that the wings members have an overall rigidity that is less than first rigidity of the center section.

Abstract: A method for manufacturing an article includes providing a plurality of flat sheets of fiber-reinforced polymer material. The method also includes forming the plurality of flat sheets of the fiber-reinforced polymer material into a plurality of curved sheets of the fiber-reinforced polymer material. Further, the method includes assembling the plurality of curved sheets of the fiber-reinforced polymer material in a tooling device to form an outer shape of the article. Moreover, the method includes securing each of the plurality of curved sheets of the fiber-reinforced polymer material together to form the article.

Abstract: A method for joining rotor blade segments of a rotor blade includes placing a first blade segment in an assembly fixture. The assembly fixture has an outer carrier and at least one bladder arranged with the outer carrier. The first blade segment has an adhesive applied at one or more locations. The method also includes arranging the first blade segment with a second blade segment at at least one joint using the assembly fixture with the adhesive positioned at the at least one joint. Further, the method includes inflating the at least one bladder to provide pressure to the at least one joint, wherein the pressure causes the adhesive to displace between the first and second blade segments at the at least one joint, thereby securing the first and second blade segments together at the at least one joint. Moreover, the method includes maintaining the pressure via the at least one inflated bladder to allow the adhesive to cure, thereby securing the first and second blade segments together.

Abstract: The present invention relates to a method of manufacturing a wind turbine blade comprising the steps of manufacturing a pressure shell halves and arranging a spar structure (62) within one of the shell halves. The spar structure (62) comprises two parts releasably coupled to each other. The method results in a segmented wind turbine blade for easy transportation and re-assembly.
