Abstract
A method for manufacturing a shell 36 and 38, is disclosed. The method includes laying one or more layers of fibres, on a surface of a mould 9 to form at least a portion of a shell half structure 36 and 38. A first panel 11 defined with noise reduction members 11a is positioned adjacent to the one or more layers of fibres on the surface of the mould 9. Further, resin is infused through the one or more layers of fiber and the first panel 11 and is subsequently cured to obtain the shell half structure 36 or 38, where the first panel 11 with noise reduction members 11a adheres to the shell half structure 36 and 38 upon curing the infused resin.

A method for manufacturing a shell (36 and 38), the method comprising:
- laying one or more layers of fibers, on a surface of a mould (9) to form at least a portion of a shell half structure (36 and 38);
- positioning a first panel (11) defined with noise reduction members (11a) adjacent the one or more layers of fibers on the surface of the mould (9);
- fusing a peel ply (15) on a first region (A);
- following the fusing of the peel ply (15) on the first region (A), infusing resin through the one or more layers of fibers and the first panel (11), and subsequently curing the same to obtain the shell half structure (36 or 38), wherein the first panel (11) with noise reduction members (11a) adheres to the shell half structure (36 and 38) upon curing the infused resin;
- and
- adjoining a second panel (13) with the first panel (11), wherein the second panel (13) is defined with projections (13a) complementing a profile of the noise reduction members (11a).
A method of manufacturing a wind turbine blade (10) having a profiled contour including a pressure side and a suction side, and a leading edge (18) and a trailing edge (20) with a chord having a chord length extending therebetween, the wind turbine blade (10) extending in a spanwise direction between a root end and a tip end, the method comprises:
- laying one or more layers of fibers, on a surface of a mould (9) to form a first shell half structure (36) and a second shell half structure (38) separately;
- joining a first panel (11) defined with noise reduction members (11a) to at least one of a leading edge (18) and a trailing edge (20) of the at least one of first shell half structure (36) and the second shell half structure (38);
- fusing a peel ply (15) on a first region (A);
- following the fusing of the peel ply (15) on the first region (A), infusing resin through the one or more layers of fibers and the first panel (11), and subsequently curing the same to obtain one of the first shell half structure or the second shell half structure (36 or 38), wherein the first panel (11) with noise reduction members (11a) adheres to the one of the first shell half structure or the second shell half structure (36 and 38) upon curing the infused resin;
- adjoining a second panel (13) with the first panel (11), wherein the second panel (13) is defined with projections (13a) complementing the profile of the noise reduction members (11a), wherein the projections (13a) defined in the second panel (13) mate with the noise reduction members (11a) of the first panel 11 defining the first region (A);
- and
- joining the first shell half structure (36) with the second shell half structure (38) to obtain the wind turbine blade (10).
