ABSTRACT:
A wind turbine blade includes a leading edge and a trailing edge. The blade has an upper shell member and a lower shell member, with each of the shell members having a forward edge bonded at the leading edge of the blade and a rearward edge. A rigid bond cap is pre-formed into a designed size and shape of the trailing edge of the blade. The bond cap includes oppositely oriented leg members bonded to the respective rearward edges of the shell members so as to be essentially flush with the upper and lower shell members. The rigid bond cap defines at least a portion of the trailing edge of the blade and a primary external bonding bridge between the upper and lower shell members at the rearward edges.
