A method for installing an add-on component onto a tip of a wind turbine blade, the associated blade, and the component, are provided. The add-on component has a span-wise end and a separated trailing edge, and is slidable onto the blade tip. Strips of a double-sided adhesive tape are attached onto
A method for installing an add-on component onto a tip of a wind turbine blade, the associated blade, and the component, are provided. The add-on component has a span-wise end and a separated trailing edge, and is slidable onto the blade tip. Strips of a double-sided adhesive tape are attached onto either or both pressure and suction side surfaces of the blade adjacent the blade tip, or onto interior surfaces of the add-on component, the tape strips having a release liner on an opposite exposed side thereof. An extension tail is configured with the release liner that extends beyond the span-wise end of the add-on component when the add-on component is placed and held at a desired position on the blade. The add-on component is slid onto and maintained in position on the blade tip and, starting from the tape strip furthest from the separated trailing edge, extension tails of the respective tape strips are sequentially peeled through the separated trailing edge and away from the add-on component.

1. A method for installing an add-on component onto a tip of a wind turbine blade, the add-on component having a span-wise end, a closed leading edge, and an at least partially separated trailing edge, and slidable onto the blade tip so as to overlap the wind turbine blade adjacent the blade tip, th
1. A method for installing an add-on component onto a tip of a wind turbine blade, the add-on component having a span-wise end, a closed leading edge, and an at least partially separated trailing edge, and slidable onto the blade tip so as to overlap the wind turbine blade adjacent the blade tip, the method comprising: attaching an adhesive side of one or more strips of a double-sided adhesive tape onto either or both of the pressure side or suction side surfaces of the wind turbine blade adjacent the blade tip or onto interior surfaces of the add-on component, the tape strips having a release liner on an opposite exposed side thereof;each of the tape strips having an extension tail from the release liner that extends beyond the span-wise end of the add-on component when the add-on component is placed and held at a desired position on the wind turbine blade;sliding the add-on component onto the blade tip; andwith the add-on component held at the desired position, starting from the tape strip furthest from the separated trailing edge, sequentially pulling the extension tail and release liner of the respective tape strips through the separated trailing edge and away from the add-on component at an angle such that that the release liner is removed along the length of the tape strip while maintaining position of the add-on component against 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 interior surface of the add-on component. 2. The method as in claim 1, wherein the add-on component is one of a tip extension or winglet. 3. The method as in claim 1, wherein the separated trailing edge has a pressure side edge and a suction side edge that extend past a trailing edge of the wind turbine blade, and further comprising bonding the pressure and suction side edges subsequent to removal of the release liners to define a trailing edge extension. 4. The method as in claim 3, further comprising providing a filler material between the pressure side edge and suction side edge at the trailing edge extension to reduce a transition point from the trailing edge of the wind turbine blade to the trailing edge extension. 5. The method as in claim 3, wherein the pressure side and the suction side edges of the separated trailing edge are offset such that one edge extends chord-wise beyond the other respective edge, and further comprising defining an aerodynamic feature in the pressure side edge or suction side edge that extends chord-wise beyond the other respective edge. 6. The method as in claim 1, wherein the separated trailing edge has a pressure side edge and a suction side edge that extend past a trailing edge of the wind turbine blade, and further comprising locating and bonding an aerodynamic insert between portions of the pressure side and suction side edges that extend past the trailing edge of the wind turbine blade. 7. The method as in claim 1, wherein the tape strips are initially attached to one or both of the suction side or pressure side surfaces of the wind turbine blade, and as the release liner is pulled away through the separated trailing edge, the adhesive under the release line attaches to an interior surface of the add-on component. 8. The method as in claim 1, further comprising trimming the extension tail from the tape strips after the add-on component is adhered to the blade tip.
