Claim 17:
18. A kit of parts for a wind turbine blade assembly, comprising:
a blade shell having an upwind shell side, a downwind shell side, a leading portion defining the leading edge of the wind turbine blade assembly, and a trailing portion arranged opposite to the leading portion and connecting the upwind shell side with the downwind shell side, wherein the trailing portion has an outwardly curving arc shape, wherein the upwind shell side and the downwind shell side are formed as separate upwind and downwind shell parts, the blade shell further comprising a joint portion having an upwind joint portion formed integrally with the upwind shell part in one piece, a downwind joint portion formed integrally with the downwind shell part in one piece, and a flange adhering to an inner surface of the upwind joint portion and to an inner surface of the downwind joint portion, so as to structurally join the upwind shell part to the downwind shell part; and
a flatback profile component having an upwind side configured for being attached substantially flush with the upwind shell side, a downwind side configured for being attached substantially flush with the downwind shell side, and a flatback side connecting the upwind side with the downwind side, the flatback side being configured to provide the wind turbine blade assembly with a flatback airfoil shape, the flatback profile component being configured for covering the trailing portion of the blade shell.
