Abstract
A turbine blade for a gas turbine engine is disclosed. The turbine blade can include at least one internal cooling path, and an internal vane disposed in the at least one internal cooling path. The internal vane can include a central portion, a first leg extending in a first direction from the central portion, and a second leg extending in a second direction from the central portion. The central portion can have a thickness greater than a thickness of the first leg or a thickness of the second leg.

A turbine blade for a gas turbine engine, comprising:
- at least one internal cooling path;
- and
- an internal vane disposed in the at least one internal cooling path, wherein the vane includes:
- a central portion;
- a first leg extending in a first direction from the central portion;
- and
- a second leg extending in a second direction from the central portion, wherein
- the central portion has a thickness greater than a thickness of the first leg or a thickness of the second leg.
A turbine blade for a gas turbine engine, comprising:
- at least one internal cooling path;
- and
- at least one vane disposed in the at least one internal cooling path, wherein the at least one vane includes:
- a central portion;
- and
- a leg extending from the central portion, wherein
- the central portion has a thickness greater than a thickness of the leg.
A turbine blade for a gas turbine engine, comprising:
- an internal cooling path;
- a first vane disposed at a first location in the cooling path;
- and
- a second vane disposed at a second location in the cooling path downstream from the first location, wherein the first and second vane each taper from a central thickness to a first thickness, and from the central thickness to a second thickness, wherein the first thickness is disposed upstream from the central thickness in the cooling path, and wherein the central thickness is disposed upstream from the second thickness in the cooling path.
