Axial oil scoop for a gas turbine engine

Abstract

An axial oil scoop for a gas turbine engine includes an outer surface with a concave profile, the outer surface includes a multiple of radial holes.

What is claimed is: 
     
         1 . An axial oil scoop for a gas turbine engine comprising:
 an outer surface with a concave profile, said outer surface includes a multiple of radial holes.   
     
     
         2 . The axial oil scoop as recited in  claim 1 , wherein said concave profile is directed toward an engine central longitudinal axis. 
     
     
         3 . The axial oil scoop as recited in  claim 1 , wherein said concave profile surrounds an engine central longitudinal axis. 
     
     
         4 . The axial oil scoop as recited in  claim 1 , wherein said outer surface is generally cylindrical. 
     
     
         5 . The axial oil scoop as recited in  claim 1 , wherein said outer surface is radially outboard an inner surface. 
     
     
         6 . The axial oil scoop as recited in  claim 5 , wherein said inner surface is angled with respect to an engine central longitudinal axis. 
     
     
         7 . The axial oil scoop as recited in  claim 6 , further comprising a back surface between said outer surface is radially outboard an inner surface. 
     
     
         8 . The axial oil scoop as recited in  claim 7 , wherein said back surface is radially directed. 
     
     
         9 . A gas turbine engine comprising:
 a shaft along an engine central longitudinal axis;   a bearing that at least partially supports said shaft;   an axial oil scoop mounted to said shaft, said axial oil scoop includes an outer surface with a concave profile.   
     
     
         10 . The gas turbine engine as recited in  claim 9 , wherein said concave profile is directed toward an engine central longitudinal axis. 
     
     
         11 . The gas turbine engine as recited in  claim 9 , wherein said concave profile surrounds an engine central longitudinal axis. 
     
     
         12 . The gas turbine engine as recited in  claim 9 , wherein said outer surface includes a multiple of radial holes. 
     
     
         13 . The gas turbine engine as recited in  claim 9 , wherein said bearing is mounted around said axial oil scoop. 
     
     
         14 . A method of lubricating a bearing that supports a shaft of a gas turbine engine comprising:
 centrifugally directing oil through a multiple of radial holes in an axial oil scoop with a concave profile.   
     
     
         15 . The method as recited in  claim 14 , further comprising:
 spraying oil generally axially toward the axial oil scoop.
