Embodiment Construction

[0067] figure 1 A conventional modern upwind wind turbine according to the so-called "Danish concept" is illustrated with a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor shaft. The rotor comprises a hub 8 and three blades 10 extending radially from the hub 8 , each blade having a blade root 16 closest to the hub and a blade tip 14 farthest from the hub 8 . The rotor has a radius denoted R.

[0068] figure 2 A schematic view of a first embodiment of a wind turbine blade 10 according to the invention is shown. The wind turbine blade 10 has the shape of a conventional wind turbine blade and includes a root region 30 closest to the hub, a profiled or airfoil region 34 furthest from the hub, and a transition between the root region 30 and the airfoil region 34. Area 32. The blade 10 includes a leading edge 18 facing the direction of rotation of the blade 10 when the blade is mounted on the hub and a trailing edge 20 facing in the opposite direction of ...

Abstract

A method of retrofitting flow-altering devices to an outer surface of a wind turbine blade is disclosed. The flow-guiding devices are of the type having a base comprising an inner side for attaching onto the surface of the wind turbine blade, and an outer side with protruding flow-altering device parts. The method comprises the steps of: a) inserting the protruding flow-altering device parts into a mounting plate so that the inner side of the flow-guiding devices are exposed from a first side of the mounting plate, b) adhering the inner side of the flow-altering devices to the surface of the wind turbine blade by applying the first side of the mounting plate onto an area of application on the surface of the wind turbine blade, and c) removing the mounting plate from area of application on the surface of the wind turbine blade.

Description

technical field [0001] The invention relates to a method of adding a fluid altering device to the outer surface of a wind turbine blade, the fluid guiding device being of the type having a base comprising an inner side for attachment to the surface of a wind turbine blade and an outer side Features prominent fluid altering device components. The invention also relates to intermediate products and kits of parts used in said method. Background technique [0002] Typically, when placing a vortex generator device such as a VG (Vortex Generator) bar on a wind turbine blade, a recess is milled or otherwise cut into the blade, into which the base plate of the vortex generator bar is inserted, Such that the top surface of the base plate is substantially flush with the blade surface. Thus, the base plate of the strip does not protrude from the blade surface, thereby reducing the risk of the strip being torn and loosened during normal use of the wind turbine blade. Furthermore, the...
