CPC classification number: F03D1/0675 , F03D80/00 , F05B2210/12 , F05B2220/30 , F05B2230/60 , F05B2240/221 , F05B2240/30
Abstract: A rotor blade 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. The first blade segment includes a beam structure having a receiving end with at least one span-wise extending pin extending therefrom. The second blade segment includes a receiving section that receives the beam structure. The receiving section includes a chord-wise member having a pin joint slot defined therethrough. The pin joint slot receives the span-wise extending pin at the receiving end of the beam structure so as to secure the first and second blade segments together. Moreover, the chord-wise member, the pin joint slot, and/or the span-wise extending pin includes at least one compliant structure formed of a compliant material that allows a deformation thereof to follow a shear deformation of the rotor blade.

Abstract: A span-wise extending pin for joining blade segments of a rotor blade includes a distal portion having a length defined by a first end and an opposing, second end. The distal portion has a conical shape extending for at least a portion of the length thereof for providing ease of insertion of the pin into a pin joint slot of one of the first and second blade segments. The pin also includes a pin portion adjacent to the distal portion. The pin portion includes a first section and a second section. The second section is configured for securing within a beam structure of the first blade segment. The first section extends span-wise from a receiving end of the beam structure. The pin also includes a proximal portion having at least a rod member that extends span-wise through and secures together the pin portion and the distal portion.
