Abstract
Official abstract text for this publication.
A turbine airfoil usable in a turbine engine and formed from at least an outboard section and an inboard section such that an inner end of the outboard section is attached to an outer end of the inboard section. The outboard section may be configured to provide a tip having adequate thickness and may extend radially inward from the tip with a generally constant cross-sectional area. The inboard section may be configured with a tapered cross-sectional area to support the outboard section.
First claim
Opening claim text (preview).
We claim: 1. A turbine airfoil, comprising: a generally elongated airfoil formed from an outer wall, and having a leading edge, a trailing edge, a pressure side, a suction side, a root at a first end of the airfoil and a tip at a second end opposite to the first end; wherein the airfoil is formed from an outboard section and an inboard section such that an inner end of the outboard section is attached to an outer end of the inboard section; wherein the outboard section has a g…
