Abstract
A method of assembling a wind turbine blade comprises providing a first blade segment comprising at least two first spar cap segments; providing a second blade segment comprising at least two second spar cap segments; inserting the second blade segment into the first blade segment wherein a spar cap cavity is formed between each set of corresponding first and second spar cap segments; injecting an adhesive into the spar cap cavities to bond the blade segments together, wherein a scarf joint is formed between each set of corresponding first and second spar cap segments.
Claims18
A method of assembling a wind turbine blade, comprising:
- providing a first blade segment comprising at least two first spar cap segments;
- providing a second blade segment comprising at least two second spar cap segments;
- attaching at least one sealing pad to the first blade segment, wherein the sealing pad is attached adjacent to a first spar cap segment;
- inserting the second blade segment into the first blade segment wherein a spar cap cavity is formed between each set of corresponding first and second spar cap segments and wherein an inner skin of the second blade segment abuts against the sealing pad, thereby sealing an interior surface of the spar cap cavity;
- and
- injecting an adhesive into the spar cap cavities to bond the blade segments together, wherein a scarf joint is formed between each set of corresponding first and second spar cap segments.
A kit for assembly of a wind turbine blade, comprising:
- a first blade segment comprising at least two first spar cap segments;
- at least one sealing pad attached to the first blade segment and located adjacent to each first spar cap segment;
- a second blade segment comprising at least two second spar cap segments, wherein the second blade segment can be inserted into the first blade segment to form a spar cap cavity and a scarf joint between each set of corresponding first and second spar cap segments, wherein an inner skin of the second blade segment abuts against the at least one sealing pad, thereby sealing an interior surface of the spar cap cavity;
- and
- an adhesive for filling the spar cap cavities and bonding the first blade segment to the second blade segment.
