Claims18
A plurality of airfoils for a wind turbine blade, each comprising;
- a blunt trailing edge;
- a substantially oval shaped suction side;
- and
- a substantially S-shaped pressure side.
The plurality of airfoils of claim L wherein each of the plurality of airfoils comprises a first width about the blunt trailing edge, a second width moving towards a leading edge, the second width being smaller than the first width, and a third width moving further towards the leading edge, the third width being larger than the first width.
A turbine blade having a plurality of airfoils, comprising:
- a first airfoil;
- the first airfoil comprising a profile substantially in accordance with non-dimensional coordinate values of X and Y set forth in Table 1;
- a second airfoil;
- the second airfoil comprising a profile substantially in accordance with non-dimensional coordinate values of X and Y set forth in Table 2;
- a third airfoil;
- the third airfoil comprising a profile substantially in accordance with non-dimensional coordinate values of X and Y set forth in Table 3;
- and
- a fourth airfoil;
- the fourth airfoil comprising a profile substantially in accordance with non-dimensional coordinate values of X and Y set forth in Table 4.
