Abstract
An example airfoil cooling arrangement includes a airfoil wall having a first face and a second face opposite the first face. The airfoil wall establishes a channel that is configured to communicate fluid between an inlet aperture and an outlet aperture. The channel includes secondary portion that branch from a primary portion. An example airfoil cooling method includes receiving a flow of fluid from a airfoil core cavity and communicating the flow of fluid through channel within a wall of the airfoil. The channel has a secondary portion branching from a primary portion.
Claims20
An airfoil cooling arrangement, comprising:
- an airfoil wall having a first face and a second face opposite the first face, the airfoil wall establishing a channel configured to communicate fluid between at least one inlet aperture and at least one outlet aperture, wherein the channel comprises a multiple of secondary portions branching from a primary portion.
An airfoil core mold insert, comprising:
- an insert that establishes a cooling channel within a airfoil wall during molding of the airfoil wall, the insert having at least one first end and at least one second end, each at least one first end configured to establish an inlet apertures, each at least one second end configured to establish an outlet aperture, wherein the channel comprises a multiple of secondary portions branching from a primary portion.
An airfoil cooling method, comprising:
- receiving a flow of fluid from a airfoil core cavity;
- and
- communicating the flow of fluid through a channel within a wall of the airfoil, the channel having a secondary portion branching from a primary portion.
