Abstract: A wind turbine blade and associated method of manufacture is described. The blade comprises an outer shell formed of first and second half shells joined together. A shear web is arranged inside the outer shell. The shear web has a web panel disposed between first and second longitudinally-extending mounting flanges. The shear web is bonded to inner surfaces of the respective half shells via a first adhesive bond line between the first mounting flange and the inner surface of the first half shell and a second adhesive bond line between the second mounting flange and the inner surface of the second half shell. One or more bond spacers are provided in the second bond line, and optionally in the first bond line. The bond spacers are compressed between a shear web mounting flange and an inner surface of a half shell and are plastically deformed. The method of making the shear web involves compressing and the one or bond spacers in the bond line(s) such that they undergo plastic deformation. This results in high quality bond lines.

Abstract: A wind turbine rotor blade (14) comprising a root portion (15) having a substantially cylindrical shape and a longitudinal axis (22), the root portion having a mounting face (25); a plurality of bores (26) in a wall of the root portion and extending from the mounting face into the root portion, the bores being configured to receive respective connecting means for connecting the wind turbine rotor blade to a wind turbine hub; wherein the plurality of bores are inclined at an angle relative to the longitudinal axis of the root portion to define a cone angle.

Abstract: A method and apparatus for assembling a wind turbine blade (10) including first and second outer shell portions (16, 18) and an internal web (12) are provided. An adhesive material (42) is applied to a top end (30) of the internal web (12) as well as the edges (62, 64) of the first outer shell portion (16) for connection to the second outer shell portion (18). Localized heat energy is applied to pre-cure the adhesive material (42) at the top end (30) of the internal web (12) before applying heat energy to fully cure all of the adhesive material (42) in the wind turbine blade (10). The pre-curing is performed by a removable localized heater device (72), and it assures that the integrity of the bond between the internal web (12) and the second outer shell portion (18) is maintained during the full curing of the blade (10), when temporary thermal deformation of the outer shell (14) sometimes occurs.
