Embodiment Construction

[0111] figure 1 An embodiment of an inventive edge seal S applied to an add-on 3, which may be any of a LEP cover, shell, TE cover, VG panel, TE panel, sensor panel, etc. is shown. The add-on 3 is attached to the outer surface 2 of the rotor blade 1 by means of an adhesive bonding layer 4 . For discussion purposes, the adhesive layer 4 may be considered an element of the attachment 3 . The height t of the add-on part 3 at its edge step 3E is the sum of the thickness of the add-on part 3 and the thickness of the adhesive layer 4 . The attachment edge 3E may be assumed to extend in the longitudinal direction of the rotor blade 1 . This figure clearly shows the "step" shape at the edge 3E of the add-on 3 . Using the inventive method, an edge seal S is formed along the add-on edge 3E. The edge seal S starts at a first point J1 at the attachment edge 3E and extends to a second point J2 whereby the height t of the seal S decreases gradually from a maximum at point J1 to a minimu...

Abstract

A method for creating a transition from an edge of an add-on part mounted on the outer surface of a rotor blade. The invention describes a method for creating a transition from an edge (3E) of an add-on part (3) mounted on the outer surface (2) of a rotor blade (1), comprising the steps: delimiting an application area on the rotor blade surface (2) and the add-on part (3) to be covered by a sealant compound (LS) with a thin and smooth masking tape (8), dispensing of the sealant (LS) on the application area, distribution of the sealant (LS), removing the masking tape (8), smoothing of a sealant (LS) transition step with a flexible tool (7). The invention further describes an according wind turbine rotor blade.

Description

technical field [0001] The present invention describes a method for creating a transition from the edge of an add-on part mounted on the outer surface of a rotor blade (i.e. providing an edge seal for a rotor blade add-on) or an edge seal for a wind turbine blade Methods. In particular, the invention relates to an aerodynamic edge seal for steps on the surface of a wind turbine blade and a method of applying such an edge seal. Background technique [0002] The aerodynamic performance of wind turbine rotor blades is highly sensitive to surface imperfections, especially in the immediate vicinity of the leading edge of the rotor blade. This presents a challenge for situations where there are steps or obstacles on the rotor blade surface, for example when applying leading edge protection (LEP) covers (also known as corrosion protection covers) and / or where eddy currents occur After the VG panel, the trailing edge (TE) panel (eg, serrated trailing edge panel), the spoiler mount...
