Abstract

A method is provided for installing an add-on component to a surface of a wind turbine blade, as well as the blade with attached add-on component, and the add-on component as a stand-alone device. A slot is defined in one or both of the pressure side or suction side surfaces of the add-on component. The adhesive side of strips of a double-sided adhesive tape are attached onto either the surface of the wind turbine blade or an interior surface of the add-on component, the tape strips having a release liner on an opposite exposed side thereof. The tape strips are arranged longitudinally along one or both sides of the slot, and each strip has an extension tail that extends beyond an edge of the add-on component when component is held at a desired position against the surface of the wind turbine blade. The extension tails are pulled along the slot at an angle such that that release liner is removed through the slot along the length of the tape strip while maintaining the desired position of the add-on component against the surface of the wind turbine blade.

First claim

What is claimed is:

1. A method for installing an add-on component to a surface of a wind turbine blade, the add-on component having a body with an open span-wise end, a pressure side surface, and a suction side surface, the method comprising:
defining a slot in one or both of the pressure side or suction side surfaces of the add-on component;
attaching an adhesive side of one or more strips of a double-sided adhesive tape onto either the surface of the wind turbine blade or an interior surface of the add-on component, the tape strips having a release liner on an opposite exposed side thereof;
the tape strips arranged longitudinally along one or both sides of the slot, and each of the tape strips having an extension tail that extends beyond an edge of the add-on component when the add-on component is placed and held at a desired position against the surface of the wind turbine blade; and
with the add-on component held at the desired position, pulling the extension tail along the slot at an angle such that that release liner is removed through the slot along the length of the tape strip while maintaining the desired position of the add-on component against the surface of the wind turbine blade to attach the exposed adhesive from under the release liner to either the surface of the wind turbine blade or the surface of the add-on component.

2. The method as in claim 1 , wherein the add-on component has a closed leading edge, a closed trailing edge, further comprising sliding the add-on component onto a tip of the wind turbine blade to the desired position such that the add-on component overlaps a portion of the wind turbine blade and extends span-wise from the tip of the wind turbine blade.

3. The method as in claim 2 , wherein the add-on component is one of a tip extension or winglet.

4. The method as in claim 1 , wherein the slot is a span-wise slot extending from the open span-wise end of the add-on component.

5. The method as in claim 1 , wherein the tape strips are initially attached to the add-on component along opposite sides of the slot, and wherein as the release liner is removed from the tape strips through the slot, the exposed adhesive from under the release line attaches to the surface of the wind turbine blade.

6. The method as in claim 1 , wherein the tape strips are initially attached to the surface of the wind turbine blade at a location corresponding to opposite sides of the slot, and wherein as the release liner is removed from the tape strips through the slot, the exposed adhesive from under the release line attaches to the surface of the add-on component.

7. The method as in claim 1 , further comprising applying an additional attaching mechanism between the add-on component and the surface of the wind turbine blade in areas between the tape strips.
