ABSTRACT:
A trailing edge attachment for a composite turbine airfoil. The trailing edge attachment may include an attachment device for attaching the trailing edge attachment to the airfoil. The attachment device may include a plurality of pins extending through the attachment device and into the trailing edge blade. The trailing edge attachment may also include a spanwise cooling channel for feeding a plurality of cooling channels extending between a leading edge of the trailing edge attachment and a trailing edge of the attachment device. The attachment device may be configured to place the leading edge of the composite airfoil in compression, thereby increasing the strength of the composite airfoil.
