Abstract
A flow path component includes a platform having at least one radially aligned face. A chordal seal extends axially from the radially aligned face. The chordal seal includes a first curved face configured to prevent edge line contact under deflection conditions while the flow path component is installed in an engine.
Claims15
A flow path component for a gas turbine engine, the flow path component comprising:
- a platform including at least one radially extending face, relative to a centerline axis of a gas turbine engine in which the flow path component is included;
- a chordal seal extending axially from said radially extending face, relative of the centerline axis;
- wherein the chordal seal includes a first curved face configured to prevent edge line contact under deflection conditions while the flow path component is installed in an engine;
- and
- wherein the chordal seal includes at least one clearance cut intrusion protruding into the chordal seal and having a radially outward facing radius of curvature.

A gas turbine engine defining a centerline axis and comprising:
- a compressor section;
- a combustor section fluidly connected to the compressor section;
- a turbine section fluidly connected to the combustor section, the turbine section including a plurality of turbine stages, each of said stages including a vane and a rotor, and wherein at least one of the vanes includes a platform including at least one radially extending face relative to the centerline axis, a chordal seal extending axially relative to the centerline axis from said radially extending face, and the chordal seal includes a first curved face configured to prevent edge line contact under deflection conditions while the flow path component is installed in the engine;
- and
- wherein the chordal seal includes at least one clearance cut intrusion protruding into the chordal seal and having a radially outward facing radius of curvature.
