<p>A wind turbine blade (16) includes an upper shell member (20) and a lower shell member (22) with an intemal cavity (25) therebetween. The shell members are joined at leading and trailing edges (24, 26) of the blade with a bond paste (34) along a bond line (36, 37) having a designed width (38). A sleeve (44) is disposed within the intemal cavity between the upper and lower shell members along at least one of the leading or trailing edges, with the bond paste contained within the sleeve. The sleeve has a ciosed end (46) that is impermeable to the bond paste and opposite sides (48) that are permeable to air and permeable to the bond paste. The bond past adheres to the upper and lower shell members through the sleeve sides and the ciosed end of the sleeve defines the design width of the bond line in the internal cavity.</p> |
