Abstract
The body of the blade is formed by a shell which is cast with the root to define an internal cavity and a chamber in the blade tip. A plurality of ducts extend from a chamber in the root through the shell and along the periphery of the shell to the chamber in the blade tip. Passages within the shell communicate the internal cavity with outlets in the trailing edge. These passages are sized to dam up the cooling air in the cavity.
