Methods of semi-permanently attaching components on a wind turbine rotor blade

A method of joining first and second blade components of a rotor blade of a wind turbine, the method comprising:

• arranging the first and second blade components together at an interface, the interface comprising a gap between the first and second blade components, each of the first and second blade components comprising a first fastening member of a re-closeable fastening assembly secured to an exterior surface thereof, the first fastening members being first zipper fastening members each having a groove formed into the surface of at least one of the first blade component or the second blade component;
• aligning a flexible sealing member at the interface so as to cover the gap, the flexible sealing member comprising corresponding, second fastening members of the re-closeable fastening assembly that align with the first fastening members on the exterior surfaces of each of the first and second blade components, the second fastening members being second zipper fastening members, the second zipper fastening members being corresponding protrusions formed into a flange of the flexible sealing member, the second zipper fastening members fitting into the first zipper fastening members;
• and
• securing the flexible sealing member at the interface to each of the first and second blade components by pressing the first and second fastening members of the fastening assembly together.

A rotor blade assembly of a wind turbine, the rotor blade assembly comprising:

• a first blade component;
• a re-closeable fastening assembly comprising, at least, a first fastening member and a corresponding, second fastening member, the first fastening member arranged with a surface of the first blade component, wherein the first fastening member is a first zipper fastening member and the second fastening member is a second zipper fastening member, the first zipper fastening member being a groove formed into the surface of the first blade component;
• an add-on component arranged adjacent to the first fastening member, the second fastening member being arranged with a surface of the add-on component such that the second fastening member aligns with the first fastening member on the surface of the first blade component, the second zipper fastening member being a corresponding protrusion formed into a flange of the add-on component, the second zipper fastening member fitting into the first zipper fastening member,
• wherein the add-on component is secured to the first blade component via the first and second fastening members.
