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.
Claims26
A wind turbine blade, comprising:
- a shell having a section with an aerodynamic profile;
- at least one girder;
- and
- at least one elongated reinforcing member connected to the shell for increasing the strength of the blade, each of the at least one elongated reinforcing member being positioned between and spaced apart from a girder of the at least one girder closest to a trailing edge of the shell and the trailing edge of the shell, each of the at least one elongated reinforcing member having a first end and a second end and extending between the first end and the second end, wherein the first end is connected to an upper part of the shell and the second end is connected to a lower part of the shell thereby preventing deformation of the trailing edge of the shell.

A method of increasing the strength of a wind turbine blade having a shell with a section having an aerodynamic profile, the method comprising:
- positioning at least one elongated reinforcing member inside the shell, each of the at least one elongated reinforcing member having a first end and a second end and extending between the first end and the second end;
- positioning at least one girder inside the shell;
- and
- connecting the first end to an upper part of the shell and the second end to a lower part of the shell, the at least one elongated reinforcing member being positioned between and spaced apart from a girder of the at least one girder closest to a trailing edge of the shell and the trailing edge of the shell.
