Flatback insert for turbine blades

A blade for use in the generation of power, the blade comprising:

• a leading edge and a trailing edge;
• a first shell portion which extends from the leading edge to the trailing edge;
• a second shell portion which extends from the leading edge to the trailing edge;
• an insert having layers of fiber fabric attached to a stiffening core, the insert is positioned between the first shell portion and the second shell portion proximate the trailing edge of the blade, an outside surface of the insert extends between and separates the first shell portion from the second shell portion at the trailing edge;
• whereby the insert provides structural stability to the trailing edge and a high lift profile for increased blade efficiency.

A method of manufacturing a blade for use in the generation of power, the blade having a first shell portion and a second shell portion, the method comprising:

• fixing an insert having a stiffening core disposed between layers of fiber fabric to a trailing edge of the second shell portion;
• applying a first clip to an inside surface of the insert proximate the second shell portion and to the second shell portion;
• applying a second clip to the inside surface of the inside surface of the insert;
• fixing a trailing edge of the insert and to the second clip;
• whereby the insert and the first and second clips provide structural stability to the trailing edge of the first shell portion and the second shell portion.
