摘要 |
The hollow interior of the blade is lined with a hollow insert and ribs to define a plurality of flow passages of narrow cross-section which connect a cooling-air chamber in the blade root with a cooling-air chamber in the blade tip. The chamber in the blade tip communicates with the interior of the insert and orifices are formed in the insert to exhaust air via a perforated partition through the trailing edge of the blade. The hollow insert is anchored in the blade root in various manners.
