Abstract

A wind turbine rotor blade including a suction side, a pressure side, a blunt trailing edge, and a trailing edge enlargement unit arranged at the blunt trailing edge and has at least two stages. The trailing edge enlargement unit has a first portion and a second portion, where a transition from the blunt trailing edge to the first portion is substantially non-perpendicular and a transition between the first and second portions is also non-perpendicular.

Claims (24)

1. A wind turbine rotor blade, comprising:

a suction side,

a pressure side,

a blunt trailing edge,

a rotor blade root region,

a rotor blade tip, and

a trailing edge enlargement unit arranged at the blunt trailing edge and has at least two stages,

wherein the trailing edge enlargement unit has a first end, a second end, a first portion and a second portion,

wherein a transition from the blunt trailing edge to the first portion at the first end of the trailing edge enlargement unit is substantially non-perpendicular and a transition between the first and second portions is non-perpendicular,

wherein the blunt trailing edge and the trailing edge enlargement unit are provided in the rotor blade root region, and

wherein the second end of the trailing edge enlargement unit is blunt.

2. The wind turbine rotor blade as set forth in claim 1 , wherein the trailing edge enlargement unit is arranged substantially perpendicularly to the blunt trailing edge.

3. A wind turbine, comprising:

at least one wind turbine rotor blade including:

a suction side,

a pressure side,

a blunt trailing edge,

a rotor blade root region,

a rotor blade tip, and

a trailing edge enlargement unit arranged at the blunt trailing edge and has at least two stages,

wherein the trailing edge enlargement unit has a first end, a second end, a first portion and a second portion,

wherein a transition from the blunt trailing edge to the first portion at the first end of the trailing edge enlargement unit is substantially non-perpendicular and a transition between the first and second portions is non-perpendicular,

wherein the blunt trailing edge and the trailing edge enlargement unit are provided in the rotor blade root region, and

wherein the second end of the trailing edge enlargement unit is blunt.
