Claim 0:
1. A wind turbine blade assembly having a longitudinal axis extending between a root end to a tip end, a chord extending transversely to the longitudinal axis between a leading edge and a trailing edge, the 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 a cross-section of the trailing portion perpendicular to the longitudinal axis having 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 positioned substantially flush with the upwind shell side, a downwind side positioned substantially flush with the downwind shell side, and a substantially planar flatback side connecting the upwind side with the downwind side, the flatback side defining the trailing edge of the wind turbine blade assembly and being shaped so as to provide the wind turbine blade assembly with a flatback airfoil shape;
wherein the flatback profile component is positioned to cover the trailing portion of the blade shell.
