Reinforced wind turbine blade

摘要

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.

主权项

1. 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 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, wherein at least one of the at least one elongated reinforcing member is a flexible wire with high tensional strength without a capability of resisting compression forces.
