Abstract

A method for manufacturing an airfoil includes casting the airfoil around a core and creating a hole through a surface of the airfoil with a water jet. The method further includes striking at least a portion of the core inside the airfoil with the water jet and removing the core from inside the airfoil.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for manufacturing an airfoil, comprising:
 a. casting the airfoil around a core;   b. creating a hole through a surface of the airfoil with a water jet;   c. striking at least a portion of the core inside the airfoil with the water jet; and   d. removing the core from inside the airfoil.   
     
     
         2 . The method as in  claim 1 , further comprising creating the core from a ceramic material. 
     
     
         3 . The method as in  claim 1 , further comprising striking the surface of the airfoil with an abrasive material in the water jet. 
     
     
         4 . The method as in  claim 1 , further comprising striking the surface of the airfoil with at least one of garnet or aluminum oxide. 
     
     
         5 . The method as in  claim 1 , further comprising striking the portion of the core with at least one of garnet or aluminum oxide. 
     
     
         6 . The method as in  claim 1 , further comprising striking the portion of the core with an abrasive material in the water jet. 
     
     
         7 . The method as in  claim 6 , further removing the abrasive material from inside the airfoil. 
     
     
         8 . The method as in  claim 1 , further comprising removing the core from the airfoil by leaching. 
     
     
         9 . A method for manufacturing an airfoil, comprising:
 a. casting a high alloy metal around a core;   b. penetrating a surface of the high alloy metal with a water jet;   c. striking at least a portion of the core inside the high alloy metal with the water jet; and   d. removing the core from inside the high alloy metal.   
     
     
         10 . The method as in  claim 9 , further comprising creating the core from a ceramic material. 
     
     
         11 . The method as in  claim 9 , further comprising striking the surface of the high alloy metal with an abrasive material in the water jet. 
     
     
         12 . The method as in  claim 9 , further comprising striking the surface of the high alloy metal with at least one of garnet or aluminum oxide. 
     
     
         13 . The method as in  claim 9 , further comprising striking the portion of the core with at least one of garnet or aluminum oxide. 
     
     
         14 . The method as in  claim 9 , further comprising striking the portion of the core with an abrasive material in the water jet. 
     
     
         15 . The method as in  claim 14 , further removing the abrasive material from inside the high alloy metal. 
     
     
         16 . The method as in  claim 9 , further comprising leaching the core from inside the high alloy metal.
