Abstract (en)
[origin: EP2921649A1] An airfoil portion (100) having an outer wall that defines a cavity for receiving cooling air. At least one insert disposed within the cavity that is configured to initially receive at least a portion of the cooling air entering the chamber of the insert and direct the cooling air through a plurality of insert apertures to cool the inner surface of the outer wall of the airfoil portion. The insert further comprises a configuration that generally conforms to the contour of the outer wall of the chamber but in spaced relation thereto. A portion of the cooling air exits the airfoil portion through a plurality of film cooling apertures formed through the outer wall. A second insert (200) forms the trailing edge channel at the end of the main insert (106).
