Abstract: A wind turbine blade, comprising: a shell with an aerodynamic profile with at least one reinforcing rod having a largest cross section between the first and the second end of the rod and extending in the internal space with its longitudinal direction between the suction side and the pressure side. The shell has a first through hole having a smallest cross section being larger than the largest cross section of the rod. The rod has a first head having a cross section larger than the smallest cross section of the first through hole and is attached to the outer surface of the shell and where the second end of the rod is attached to a second through hole in the shell by a screw having a second head resting against the outer surface of the shell, and a shank extending through the second through hole in the shell.

Abstract: A wind turbine blade comprising a shell and at least a first girder wherein the first girder is connected to an upper part of the shell and a lower part of the shell, and where the wind turbine blade comprises at least one reinforcing member having a first end and a second opposite end. The reinforcing member comprises a first part with the first end and a second part with the second opposite end and that a length adjustment member is arranged between the first and the second part of the reinforcing member, and being adapted for mutually positioning and fixing the first and the second part in at least two different distances from each other.

Abstract: The present invention relates to an airfoil shaped body with a leading edge and a trailing edge extending along the longitudinal extension of the body and defining a profile chord, the airfoil shaped body comprising an airfoil shaped facing that forms the outer surface of the airfoil shaped body and surrounds an internal volume of the body, a distance member that is connected to the facing inside the body and extends from the facing and into the internal volume of the body, and at least one reinforcing member that operates in tension for reinforcing the facing against inward deflections and that is connected to the facing inside the internal volume of the body at the same side of the profile chord as the connection of the distance member to the facing and to the distance member at a distance from the facing.

Abstract: The present invention relates to a reinforced blade for a wind turbine, particularly to a blade having at least one elongated reinforcing member connected inside the shell for increasing the strength of the blade, each of the at least one elongated reinforcing member having a first end and a second end and extending in a longitudinal direction between the first end and the second end and wherein the first end is connected to the upper part of the shell and the second end is connected to the lower part of the shell thereby decreasing peeling and shear stresses in the trailing edge of the blade.

Abstract: The invention introduces a reinforcement of a box girder of a wind turbine blade. The reinforcement prevents the transverse shear distortion of the blade structure, when the blade is loaded during operation. The reinforcement connects the corners diagonally opposite inside the girder, and fixes them in relation to each other. The reinforcement increases the blade's resistance to overall collapse. The reinforcement comprises one or more individual element, such as rods or plates.

Abstract: The present invention relates to a reinforced blade for a wind turbine, and in particular to a wind turbine blade comprising a shell having a section with an aerodynamic profile, and at least one internal reinforcing floor connected inside the shell and extending substantially along the profile chord in order to increase the strength of the blade and to prevent or reduce deformations of the surface of the blade caused by edgewise and flapwise loading of the blade structure.

Abstract: The present invention relates to the prevention of deformations in an aerodynamic profile caused by lack of resistance to the bending moment forces that are created when such a profile is loaded in operation. More specifically, the invention relates to a reinforcing element inside an aerodynamic profile and a method for the construction thereof. The profile is intended for, but not limited to, use as a wind turbine blade, an aerofoil device or as a wing profile used in the aeronautical industry.
