Abstract
An airfoil includes an airfoil wall that defines a leading end, a trailing end, a first side, and a second side. Radially-extending ribs partition the interior cavity of the airfoil into first and second cooling channels and a radial cooling passage that is situated between the first and second cooling channels. The cooling channels extend to respective first and second channel ends. A turn channel connects the first and second channel ends. The turn channel splits at the first channel end into first and second channel legs such that there is a region between the first and second channel legs. The channels legs merge at the second channel end. The radial cooling passage extends through the region between the first and second channel legs.

An airfoil comprising:
- an airfoil wall defining a leading end, a trailing end, a first side, and a second side, the airfoil wall circumscribing an interior cavity;
- and
- radially-extending ribs that partition the interior cavity into first and second cooling channels and a radial cooling passage situated between the first and second cooling channels, the first and second cooling channels extending to respective first and second channel ends;
- and
- a turn channel connecting the first and second channel ends, the turn channel splitting at the first channel end into first and second channel legs such that there is a region between the first and second channel legs, the first and second channels legs merging at the second channel end, the radial cooling passage narrowing to a neck portion, and the neck portion extending through the region between the first and second channel legs.
A gas turbine engine comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor,
- the turbine section having an airfoil that includes
- an airfoil wall defining a leading end, a trailing end, a first side, and a second side, the airfoil wall circumscribing an interior cavity,
- radially-extending ribs that partition the interior cavity into first and second cooling channels and a radial cooling passage situated between the first and second cooling channels, the first and second cooling channels extending to respective first and second channel ends, and
- a turn channel connecting the first and second channel ends, the turn channel including a middle section between first and second ear sections, and the middle section splitting at the first channel end into first and second channel legs such that there is a region between the first and second channel legs, the first and second channels legs merging at the second channel end, the radial cooling passage extending through the region between the first and second channel legs.
