20080256795 | WIND TURBINE BLADE HAVING CURVED CAMBER AND METHOD OF MANUFACTURING SAME - A wind turbine blade for a vertical axis wind turbine (VAWT) having a curved camber and a method of manufacturing same is disclosed. The method of manufacturing a turbine blade comprises determining the profile of an airfoil of the blade and forming the blade having the airfoil with the translated profile. The step of determining the profile of an airfoil of the blade comprises selecting a symmetrical airfoil having a straight mean camber line and a desired chord length; selecting a circular segment having the same radius as a path traveled by the blade around a hub of the VAWT and locating the circular segment to contact the mean camber line at at least one point; translating the mean camber line of the symmetrical airfoil such that it overlaps with the circular segment; and determining the profile of the airfoil blade by translating the profile of the symmetrical airfoil to correspond with the translated mean camber line of the symmetrical airfoil. | 10-23-2008 |
