AIRFOIL PLATFORM WITH COOLING FEED ORIFICES

An airfoil platform includes a platform body (100) having an arcuate base (108) defining a centerline axis (A). A rail (110) extends radially outboard from a side of the arcuate base. A feed orifice (114) is defined at least partially in the rail. The inner diameter edge (122) of an axially facing o...

More Information
Summary:An airfoil platform includes a platform body (100) having an arcuate base (108) defining a centerline axis (A). A rail (110) extends radially outboard from a side of the arcuate base. A feed orifice (114) is defined at least partially in the rail. The inner diameter edge (122) of an axially facing opening (124) of the feed orifice is spaced apart radially outboard of an outer diameter surface of the arcuate base. A method for manufacturing an airfoil platform includes providing an airfoil platform body (100) and forming the feed orifice (114) through the rail. Forming the feed orifice through the rail includes forming the feed orifice radially outboard of and spaced apart from the outer diameter surface of the arcuate base.
