Abstract
An airfoil according to an example of the present disclosure includes, among other things, an airfoil body defining a cavity, and a baffle including a baffle body including sidewalls and defining an internal passage for conveying coolant. The baffle body is situated in the cavity such that a majority of external surfaces of the sidewalls abut the cavity.
Claims20
An airfoil, comprising:
- an airfoil body extending in a chordwise direction between a leading edge and a trailing edge, the airfoil body extending in a thickness direction between pressure and suction sides, the airfoil body defining a first cavity and a second cavity each bounded by external walls of the airfoil body, and the airfoil body including an internal rib spanning between the pressure and suction sides to bound the first cavity and the second cavity;
- and
- a baffle including a baffle body including sidewalls and defining an internal passage in the baffle body for conveying coolant, the baffle body situated in the first cavity such that a majority of external surfaces of the sidewalls abut internal surfaces of the airfoil body that define the first cavity, and wherein the internal passage is fluidly isolated from the first cavity.
A gas turbine engine, comprising:
- a rotor spaced axially from a vane,
- wherein at least one of the rotor and the vane includes an airfoil body, the airfoil body including external walls extending between a leading edge and a trailing edge, the external walls defining a first cavity and a second cavity separated by an internal rib, the internal rib spanning between pressure and suction sides of the airfoil body to bound the first cavity and the second cavity;
- and
- a baffle including a baffle body defining an internal passage in the baffle body for conveying coolant, sidewalls of the baffle body having a complementary geometry with the first cavity, and wherein the internal passage is fluidly isolated from the first cavity, wherein the sidewalls of the baffle body abut a majority of surfaces of the airfoil body that define the first cavity.
