MANUFACTURING METHOD OF FLAT-BACK SHAPED COMPOSITE WIND BLADE

摘要

The present invention relates to a manufacturing method of a flat-tailing edge shaped blade of an airfoil in a predetermined area, and comprises: a first step of forming respectively an upper member and a lower member; a second step of separating a room portion wherein the upper member and the lower member are connected to the hub, the airfoil formed apart from a predetermined distance with a root portion, and a converting portion placed between the airfoil portion and the root portion; a third step of forming each blunt portion partitioned by a first bent portion in the first bent portion, and an upper member by bending a tailing edge portion of the upper member, forming a second bend by bonding the tailing edge of the lower member and the end portion of the first bent portion; and a fourth step wherein a reinforcing member is located on at least one side of the outer surface and the inner surface.
