Abstract

The present invention relates to a mounting structure for securing a wind turbine blade portion to a testing apparatus for mechanical testing, comprising: a base component; at least one cantilever arm attached to, and extending from, the base component; and at least one tie rod configured to extend through the blade portion. The mounting structure is configured such that a root end of the blade portion can be secured in place at the cantilever arm by a clamping force exerted by the at least one tie rod. Another aspect of the invention relates to a method of installing a blade portion into the testing apparatus.

Claims (20)

1. A mounting structure for securing a wind turbine blade portion to a testing apparatus for mechanical testing, the mounting structure comprising: a base component; at least one cantilever arm attached to, and extending from, the base component; and at least one tie rod configured to extend through the blade portion; wherein the mounting structure is configured such that a root end of the blade portion can be secured in place by the at least one cantilever arm by a clamping force exerted by the at least one tie rod.
2. The mounting structure of claim 1, wherein the cantilever arm is at least two cantilever arms, preferably four cantilever arms.
3. The mounting structure of claim 1 or claim 2, comprising a profile insert having at least one contacting wall defining an opening in which at least part of the blade portion can be received, the contacting wall being shaped so as to align with and contact a blade portion.
4. The mounting structure of claim 3, wherein the profile insert comprises at least two separable parts, each part having a contacting wall, the contacting walls each contacting opposing sides of a blade portion when a blade portion is installed in the mounting structure.
5. The mounting structure of any of the preceding claims, further comprising at least one inner profile, configured to be received in the wind turbine blade portion.
6. The mounting structure of any of claims 2 to 5, comprising a pair of cross-beams extending in a transverse direction between the cantilever arms.
7. The mounting structure of claim 6, comprising at least two pairs of cross-beams, one pair spaced apart from another pair along the cantilever arms in the direction of extension of the cantilever arms.
8. The mounting structure of claim 6 or claim 7, wherein one or more of the cross beams is adjustable relative to another of the cross-beams.
9. The mounting structure of any of the preceding claims, wherein a root end of at least one cantilever arm is fixed in position to the base component.
10. The mounting structure of any of the preceding claims, wherein a root end of at least one cantilever arm is adjustably connected to the base component.
11. The mounting structure of claim 10, wherein the adjustable connection comprises an elongate aperture and a pin, the pin being translatable along the elongate aperture when in an installed state.
12. The mounting structure of claim 11 , wherein the elongate aperture extends in the base component in a radial direction, and/or a transverse direction defined by the blade portion cross-section when the blade portion is fully installed into the mounting structure.
13. The mounting structure of any of the preceding claims, wherein the base component is a base plate, the base plate defining a central aperture to provide access from a rear side of the mounting structure to the blade portion.
14. A wind turbine blade portion test assembly, comprising: the mounting structure of any of the preceding claims, and a wind turbine blade portion.
15. The wind turbine blade portion test assembly of claim 14, wherein the or each tie rod extends to one side of at least one spar cap of the wind turbine blade portion and/or the or each tie rod extends along a side of a shear web of the wind turbine blade portion.
16. The wind turbine blade portion test assembly of claim 14 or 15, wherein a root end face of the wind turbine blade portion projects from the one or more tie rods towards the base component and/or wherein a tip end of the wind turbine blade portion projects from the one or more tie rods away from the mounting structure.
17. The wind turbine blade portion test assembly of any of claims 14 to 16, wherein the root end face of the wind turbine blade portion is not directly attached to the mounting structure.
18. The wind turbine blade portion test assembly of any of claims 14 to 17, further comprising a ring bearing configured to allow rotation of the blade portion, the ring bearing being fastened to the base component .
19. A method of installing a blade portion into a testing apparatus, comprising: providing a blade portion, providing the mounting structure of any of claims 1 to 13, locating a root end of the blade portion at the at least one cantilever arm, and securing the cantilever arm so as to exert a clamping force from the cantilever arm on the blade portion.
20. The method of claim 19, wherein the blade portion is a tip portion or an intermediate portion of a multiple-portion blade.
