Gas turbine engine component cooling cavity with vortex promoting features

Abstract

A component according to an exemplary aspect of the present disclosure includes, among other things, a body, a wall extending inside of the body and a plurality of vortex promoting features arranged in a helical pattern along the wall.

1 . A method, comprising:
 additively manufacturing a casting article layer-by-layer using an additive manufacturing process; and   casting a component to include a plurality of vortex promoting features arranged in a helical pattern along a wall of the component; using the casting article.   
     
     
         2 . The method as recited in  claim 1 , wherein the component is made of a ceramic material. 
     
     
         3 . The method as recited in  claim 1 , wherein the component is made of a refractory metal. 
     
     
         4 . The method as recited in  claim 1 , wherein the casting article includes a body having a plurality of indents extending into the body, and the indents are arranged in a helical pattern to form the plurality of vortex promoting features. 
     
     
         5 . The method as recited in  claim 1 , wherein the step of manufacturing includes building the component to include the plurality of vortex promoting features layer-by-layer using an additive manufacturing process. 
     
     
         6 . The method as recited in  claim 5 , wherein the casting article is a casting core. 
     
     
         7 . The method as recited in  claim 1 , wherein the casting article is a casting core. 
     
     
         8 . The method as recited in  claim 1 , wherein the additive manufacturing step includes building the casting article layer by layer by delivering a powdered metal to a build platform, and melting a layer of powdered material. 
     
     
         9 . The method as recited in  claim 8 , comprising:
 moving the build platform;   adding a second layer of powdered material; and   melting the second layer.   
     
     
         10 . The method as recited in  claim 8 , wherein the melting is performed by a laser. 
     
     
         11 . The method as recited in  claim 8 , wherein the melting is performed by an electron beam melting device. 
     
     
         12 . The method as recited in  claim 8 , wherein the powdered material is a ceramic material. 
     
     
         13 . The method as recited in  claim 8 , wherein the powdered material is a refractory metal material.
