First Claim
Patent Images
1. An air cooled turbine rotor blade comprising:
- an airfoil with a leading edge region;
a leading edge impingement cavity located in the leading edge region;
a row of film cooling slots in the leading edge region extending along a spanwise direction of the airfoil;
a metering hole connected each of the film cooling slots to the leading edge impingement cavity;
each of the film cooling slots having two side walls that form a divergent cooling air flow; and
,each of the film cooling slots having a top and bottom wall that form a convergent cooling air flow.

Abstract
A turbine blade with a leading edge region of the airfoil having rows of film cooling slots each connected by one or more metering holes to a cooling air impingement cavity, where the film slots have both a convergent and a divergent shape. The side walls converge while the top and bottom walls diverge within each slot and form a very narrow but tall slot opening on the leading edge surface of the blade.
