Abstract: The present invention relates to a wind turbine blade comprising an aerodynamic shell having an outer surface forming at least part of an exterior surface of the wind turbine blade and an inner surface. An access window extends through the shell. A panel is arranged within a recessed portion at the inner surface of the shell adjacent to the access window for closing the access window.

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.

Abstract: A wind turbine blade comprising a plurality of spar components extending along the longitudinal axis and providing the main bending stiffness of the wind turbine blade a major principal axis defining a structural pitch angle of at least 1° with respect to a chord line, and including: one or more suction-side spar caps each having a centre line; one or more pressure-side spar caps each having a centre line; and one or more shear webs distributed around a central shear web line and at least one of which being connected to first spar caps, wherein at least one suction-side spar cap centre lines is arranged with a first chordwise distance to the central shear web line, and at least one pressure-side spar cap centre lines is arranged with a second, different, chordwise distance to the central shear web line.
