Abstract
A gas turbine engine includes a platform that has a gas path side, a non-gas path side, a first mate face, and a second mate face. The second mate face has a beveled edge sloping towards the first mate face. The gas turbine engine also includes a coverplate that includes a first bend, a flat portion substantially parallel to the first mate face and a first wing substantially parallel to the second mate face.
Claims16
A gas turbine engine component comprising:
- a platform having a gas path side, a non-gas path side, a platform floor, a first mate face parallel to the platform floor, and a second mate face having a beveled edge sloping towards the first mate face such that the second mate face forms a first angle with the first mate face;
- and
- a coverplate including a first bend of a second angle that is equal to the first angle, a flat portion coupled to the first mate face and parallel to the first mate face, and a first wing coupled to the second mate face and parallel to the second mate face,
- wherein the platform and the coverplate define a cavity therebetween, and a first distance between the first wing and the platform floor is greater than a second distance between the flat portion and the platform floor.
