A method of attaching first and second aerofoil sections to each other is disclosed. The method comprises the steps of: positioning one aerofoil section in an initial assembly orientation with respect to the other aerofoil section so that hinge elements on each aerofoil section are in alignment with each other, inserting a hinge shaft through said aligned hinge elements to initially couple the aerofoil sections together whilst the aerofoil sections are in their initial assembly orientation; and rotating one aerofoil section relative to the other aerofoil section about a compound angle defined by the hinge shaft into a second orientation in which the aerofoil sections are in their final, assembled orientation relative to each other. An aerofoil assembly is also disclosed.

1. A method of attaching first and second aerofoil sections to each other comprising the steps of: (a) positioning one aerofoil section in an initial assembly orientation with respect to the other aerofoil section so that hinge elements on each aerofoil section are in alignment with each other,(b) inserting a hinge shaft through said aligned hinge elements to initially couple the aerofoil sections together whilst the aerofoil sections are in their initial assembly orientation;(c) rotating one aerofoil section relative to the other aerofoil section about a compound angle defined by the hinge shaft into a second orientation in which the aerofoil sections are in their final, assembled orientation relative to each other. 2. A method according to claim 1, wherein the step of rotating one aerofoil section comprises the step of rotating that aerofoil section such that both aerofoil sections lie in substantially the same geometric plane when in their final, assembled orientation. 3. A method according to claim 1, wherein the each aerofoil assembly has separation surfaces and the method includes the step of rotating one aerofoil section relative to the other aerofoil section such that the separation surfaces abut when the aerofoil sections are in their final assembled orientation relative to each other. 4. A method according to claim 3, wherein the method includes the step of passing fixings through the separation surfaces and coupling those fixings to lock the aerofoil sections in their final, assembled orientation relative to each other and prevent rotation about said hinge. 5. A method according to claim 1, wherein the method includes the step of configuring the aerofoil sections such that the hinge shaft lies at an angle to a vertical axis in both a longitudinal and a chordal direction to create the compound angle, when the hinge shaft is inserted into said aligned hinge elements. 6. A method according to claim 5, wherein the method includes the step of configuring the aerofoil sections such that an upper end of the hinge shaft is tilted towards the tip section in the longitudinal direction and towards a trailing edge of the aerofoil sections in the chordal direction. 7. A method according to claim 1, wherein the aerofoil sections comprise an inboard section and a tip section, the method including the step of rotating the tip section relative to the stationary inboard section about a compound angle defined by the hinge shaft into a second orientation in which the tip section is in its final, assembled orientation relative to the inboard section. 8. A method according to claim 7, wherein the inboard section is part of a wing of an aircraft having a root end for attachment to a fuselage of an aircraft and, a remote end, the tip section comprising a winglet or ‘sharklet’ that is attached to said remote end by said method. 9. An aerofoil assembly comprising first and second aerofoil sections, each aerofoil section having cooperating hinge elements that align when the aerofoil sections are positioned relative to each other in an initial assembly position, and a hinge shaft that is inserted through said aligned hinge elements to couple said aerofoil sections together whilst the aerofoil sections are in their initial assembly position, the cooperating hinge elements being configured such that the axis of the hinge shaft lies at a compound angle relative to two axes of said aerofoil assembly so that the aerofoil sections can be rotated relative to each other into a fully assembled position. 10. An aerofoil assembly according to claim 9, wherein each aerofoil section has separation surfaces that abut when the aerofoil sections are in their final assembled orientation relative to each other. 11. An aerofoil assembly according to claim 10, wherein the hinge elements and separation surfaces are configured such that, when the separation surfaces abut, both aerofoil sections lie in substantially the same geometric plane in their final, assembled, orientation. 12. An aerofoil assembly according to claim 10, comprising fixings that extend through the separation surfaces to lock the aerofoil sections in their final, assembled orientation relative to each other and prevent rotation about said hinge. 13. An aerofoil assembly according to claim 9, wherein the aerofoil sections are configured such that the hinge shaft lies at an angle to a vertical axis in both a longitudinal and a chordal direction to create the compound angle, when the hinge shaft is inserted into said aligned hinge elements. 14. An aerofoil assembly according to claim 1, wherein the aerofoil sections comprise an inboard section and a tip section, the tip section being rotatable relative to the stationary inboard section about a compound angle defined by the hinge shaft into a second orientation in which the tip section is in its final, assembled orientation relative to the inboard section. 15. An aerofoil assembly according to claim 14, wherein the aerofoil sections are configured such that an upper end of the hinge shaft is tilted towards the tip section in the longitudinal direction and towards a trailing edge of the aerofoil sections in the chordal direction. 16. An aerofoil assembly according to claim 14, wherein the inboard section is part of a wing of an aircraft having a root end for attachment to a fuselage of an aircraft and, a remote end, the tip section comprising a winglet or ‘sharklet’ that is attachable to said remote end.
