Abstract
Official abstract text for this publication.
The present disclosure is directed to methods for attaching a plurality of surface features to a rotor blade of a wind turbine. Such methods may include direct molding of the surface features to the rotor blade, bonding arrays of connected components to the rotor blade and subsequently removing connections between components, as well as using a flexible template with or without a tinted adhesive.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for attaching a plurality of surface features to a rotor blade of a wind turbine, the method comprising: locating a flexible template at a desired location on either of a suction side or a pressure side of the rotor blade, the flexible template having a plurality of hole locations, each hole location corresponding to an attachment location for one of the surface features; spraying a tinted adhesive around an outer periphery of each of the hole locations, the tinted adhesive part of a first attachment feature applied around the outer periphery of each of the hole locations; applying a second attachment feature within the first attachment feature, the second attachment feature spaced from the first attachment feature in a center of the hole location, the first and second attachment features comprising at least one of an adhesive or a double-side tape, the double-side tape comprising an inner acrylic foam layer disposed between a first outer adhesive layer and a second outer adhesive layer; removing the flexible template from the rotor blade; and, securing at least one of the plurality of surface features at each of the attachment locations marked by the tinted adhesive via the first and second attachment features. 2. The method of claim 1 , wherein the first attachment feature comprises the double-sided tape and the second attachment feature comprises the adhesive.
