Abstract
Disclosed is a wind turbine blade and a method for its manufacture. The wind turbine blade comprises an upwind side shell part, a downwind side shell part, a leading edge and a trailing edge. A flatback web is arranged at the trailing edge, which couples the upwind side shell part with the downwind side shell part, wherein the flatback web comprises at least one U-shaped end section with a recess, into which the upwind side shell part and/or the downwind side shell part is inserted and bonded to the U-shaped end section by an adhesive.
Claims15
A wind turbine blade, comprising:
- an upwind side shell part;
- a downwind side shell part;
- a leading edge and a trailing edge;
- and
- a flatback web being arranged at the trailing edge, which couples the upwind side shell part with the downwind side shell part, wherein the flatback web comprises at least one U-shaped end section with a recess, into which at least part of the upwind side shell part and/or at least part of the downwind side shell part is inserted and bonded to the U-shaped end section, and wherein the flatback web extends vertically with respect to a cross-section of the wind turbine blade.
A method for manufacturing a wind turbine blade, the method comprising the steps of:
- providing an upwind side shell part and a downwind side shell part, each shell part having a leading edge end and a trailing edge end;
- providing a flatback web with one or more U-shaped end sections, each end section comprising a recess;
- applying adhesive into the recesses of the respective U-shaped end sections of the flatback web and/or onto the respective trailing edge ends of the upwind side shell part and the downwind side shell part;
- and
- pushing the flatback web onto the upwind side shell part and the downwind side shell part such that at least part of the upwind side shell part and the downwind side shell part is inserted into the recesses of the respective U-shaped end sections of the flatback web, to form at least part of a trailing edge of the wind turbine blade, wherein the flatback web extends vertically with respect to a cross-section of the wind turbine blade.
