Beveled coverplate
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.
1. A gas turbine engine assembly, comprising:
a compressor section;
a combustor section; and
a turbine section, wherein at least one of the compressor section or the turbine section includes a component that includes:
a platform having:
a gas path side,
a non-gas path side,
a platform floor on the non-gas path side,
a first mate face on the non-gas path side offset from the platform floor by a first distance, the first mate face parallel to the platform floor,
a second mate face on the non-gas path side, the second mate face having a beveled edge sloping towards the platform floor and offset from the platform floor by a second distance that is larger than the first distance, and
a coverplate including a flat portion parallel to and contacting the first mate face of the platform, a first wing parallel to and contacting the second mate face of the platform, and a first bend extending from the flat portion to the first wing, wherein the second mate face of the platform and the first wing of the coverplate are joined together to form a seal.
2. The assembly of claim 1 , further comprising a duct adapted to channel coolant from the compressor section to the non-gas path side of the platform.
3. The assembly of claim 1 , further comprising a cavity defined by the coverplate and the platform, wherein the coverplate defines a cooling hole adapted to allow coolant to flow into the cavity.
4. A gas turbine engine assembly, comprising:
a compressor section;
a combustor section; and
a turbine section, wherein at least one of the compressor section or the turbine section includes a component that includes:
a platform having:
a gas path side,
a non-gas path side,
a platform floor on the non-gas path side,
a first mate face on the non-gas path side offset from the platform floor by a first distance, the first mate face parallel to the platform floor,
a second mate face on the non-gas path side, the second mate face having a beveled edge sloping towards the platform floor and offset from the platform floor by a second distance that is larger than the first distance, and
a coverplate including a flat portion parallel to and contacting the first mate face of the platform, a first wing parallel to and contacting the second mate face of the platform, and a first bend extending from the flat portion to the first wing;
wherein the platform is an inner diameter platform, and
wherein the second mate face of the platform and the first wing of the coverplate are joined together to form a seal.
