A blade (10) for a rotor of a wind turbine (2) is disclosed. The blade is assembled from an inboard blade part (50) closest to the hub and an outboard blade part (110) farthest from the hub of the wind turbine. The inboard part (50) comprises a load carrying structure (60) with a first aerodynamic shell (70) fitted to the load carrying structure (60), and the outboard part (110) comprises a blade shell (141, 143) with a load carrying structure (142, 144) integrated in the blade shell (141, 143).

1. A blade (10) for a rotor of a wind turbine (2) having a substantially horizontal rotor shaft, said rotor comprising a hub (8), from which the blade (10) extends substantially in a radial direction when mounted to the hub (8), the blade having a longitudinal direction (r) with a tip end (16) and a
1. A blade (10) for a rotor of a wind turbine (2) having a substantially horizontal rotor shaft, said rotor comprising a hub (8), from which the blade (10) extends substantially in a radial direction when mounted to the hub (8), the blade having a longitudinal direction (r) with a tip end (16) and a root end (14) and a transverse direction as well as having a blade length (L), the blade further comprising: a profiled contour including a pressure side and a suction side, as well as a leading edge (18) and a trailing edge (20) with a chord having a chord length (c) extending there between, the profiled contour, when being impacted by an incident airflow, generating a lift, whereinthe blade is assembled from an inboard blade part (50) closest to the hub and an outboard blade part (110) farthest from the hub, whereinthe inboard blade part (50) comprises a load carrying structure (60) in a form of a spar or a beam with a first aerodynamic shell (70) mounted to the spar or beam, andthe outboard blade part (110) comprises a blade shell (141, 143) with a load carrying structure (142, 144) in a form of a principal laminate integrated in the blade shell (141, 143);wherein the outboard blade part is pitchable in relation to the inboard blade part, andwherein a profiled contour of the inboard blade part substantially flushed with a profiled contour of the outboard blade part in a zero pitch position of the blade. 2. The blade according claim 1, wherein the load carrying structure of the inboard blade part is made of steel, aluminium, or fibre-reinforced polymer. 3. The blade according to claim 1, wherein the outboard blade part comprises a first blade part comprising a pressure side shell part with a pressure side principal laminate, and a suction side shell part with a suction side principal laminate. 4. The blade according to claim 3, wherein at least one shear web is mounted between the pressure side principal laminate and the suction side principal laminate. 5. The blade according to claim 1, wherein the outboard blade part is made as a fibre-reinforced structure. 6. The blade according to claim 1, wherein an assembly plane between the inboard blade part and the outboard blade part form an acute angle with a root plane of the inboard blade part. 7. The blade according to claim 1, wherein a length of the outboard part is between 60% and 85% of the length (L) of the blade. 8. The blade according to claim 7, wherein the length of the outboard blade part is between 60% and 80% of the length (L) of the blade. 9. The blade according to claim 8, wherein the length of the outboard blade part is between 65% and 80% of the length (L) of the blade. 10. The blade according to claim 9, wherein the length of the outboard blade part is between 65% and 75% of the length (L) of the blade. 11. The blade according to claim 1, wherein the first aerodynamic shell of the inboard blade part is made of a fibre-reinforced polymer material. 12. The wind turbine blade according to claim 1, wherein a longitudinal centre axis of the blade is displaced from a longitudinal centre axis of the outboard blade part. 13. A wind turbine, comprising: a plurality of blades, each said blade having a longitudinal direction (r) with a tip end (16) and a root end (14) and a transverse direction as well as having a blade length (L), each said blade further comprising: a profiled contour including a pressure side and a suction side, as well as a leading edge (18) and a trailing edge (20) with a chord having a chord length (c) extending therebetween, the profiled contour, when being impacted by an incident airflow, generating a lift, whereineach said blade is assembled from an inboard blade part (50) closest to the hub and an outboard blade part (110) farthest from the hub, whereinthe inboard blade part (50) comprises a load carrying structure (60) in a form of a spar or a beam with a first aerodynamic shell (70) mounted to the spar or beam, andthe outboard blade part (110) comprises a blade shell (141, 143) with a load carrying structure (142, 144) in a form of a principal laminate integrated in the blade shell (141, 143),wherein the outboard blade part is pitchable in relation to the inboard blade part, andwherein a profiled contour of the inboard blade part substantially flushed with a profiled contour of the outboard blade part in a zero pitch position of the blade; anda hub on a main shaft having a substantially horizontal centre axis, wherein the plurality of blades extend substantially radially from the hub, the blades together with the hub constituting a rotor with a rotor plane. 14. The wind turbine of claim 13, wherein the number of blades is two or three. 15. A method of manufacturing a blade, wherein the method comprises the steps of: a) manufacturing a load carrying structure (60) in a form of a spar or a beam for an inboard blade part (50),b) connecting a first aerodynamic shell (70) to the load carrying structure of the inboard blade part, wherein the first aerodynamic shell (70) is mounted to the spar or beam,c) manufacturing an outboard blade part (110) with a blade shell (141, 143) having an integrated load carrying structure (142, 144) in a form of a principal laminate, andd) connecting the outboard blade part (110) to the inboard blade part (50);wherein the outboard blade part is pitchable in relation to the inboard blade part, andwherein a profiled contour of the inboard blade part substantially flushed with a profiled contour of the outboard blade part in a zero pitch position of the blade.
