Problems solved by technology

[0006] The prior art solutions are cumbersome and do not provide an easy way of handling and easily applying the vortex generator device to a wind turbine blade
This problem is even more pronounced when multiple devices are to be retrofitted to the surface of the blade

Embodiment Construction

[0073] figure 1 A conventional modern upwind wind turbine 2 according to the so-called "Danish concept" is illustrated, having a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor axis. The rotor includes a hub 8 and three wind turbine blades 10 extending radially from the hub 8 , each blade having a blade root 16 closest to the hub and a blade tip 14 furthest away from the hub 8 . The rotor has a radius denoted R.

[0074] figure 2 A schematic perspective view of a wind turbine blade 10 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, an airfoil or airfoil region 34 furthest from the hub, and a transition region 32 between the root region 30 and the airfoil region 34 . The blade 10 includes a leading edge 18 facing in 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 the leading...

Abstract

A method of mounting a flow modification device on a wind turbine blade, a mounting device and a flow modification device of the type having a base comprising a surface for attachment to the wind turbine blade are disclosed. an inner side, and an outer side having one or more flow altering device portions projecting from the base. The method includes providing a mounting device having a mounting panel supporting one or more flow modifying devices, the one or more flow modifying devices including a first flow modifying device; arranging the mounting panel on an application area on a surface of a wind turbine blade, having an adhesive material between the inside of the first flow altering device and the surface of the wind turbine blade, and having a seal between the mounting panel and the surface to form a cavity between the mounting panel and the surface of the wind turbine blade; in the cavity Negative pressure is applied; negative pressure in the cavity is released; and the mounting panel is removed from the application area on the surface of the wind turbine blade.

Description

technical field [0001] The present invention relates to a method of retrofitting a flow modification device, such as a vortex generator device and / or a turbulence generator device, to the outer surface of a wind turbine blade, the flow modification device being of the type having a base comprising Attached to the inner side on the surface of the wind turbine blade, and the outer side with one or more protruding flow altering device portions. Background technique [0002] Typically, when a vortex generator (VG) device, such as a VG strip, is assembled on a wind turbine blade, grooves are milled or otherwise cut into the blade into which the base plate of the vortex generator strip is inserted such that the base plate The top surface of the blade is substantially flush with the surface of the blade. Consequently, the base plate of the strip does not protrude from the surface of the blade, thereby reducing the risk of the strip being torn loose during normal use of the wind tu...
