TURBINE ENGINE COMPONENT WITH DIFFUSER HOLES
First Claim
1. A turbine component having a component wall with inner and outer surfaces wherein a diffuser hole passes through the component wall between the inner surface and the outer surface, the diffuser hole having a hole axis and comprising:
- a metering section extending from an inlet at the inner surface to a junction plane between the inner and outer surfaces; and
a diffuser section extending from the junction plane to an outlet at the outer surface, and increasing in flow area from the junction plane to the outlet, the diffuser section having an upstream portion defining a first area ratio and a downstream portion defining a second area ratio different from the second area ratio.

Abstract
A turbine component includes a component wall with inner and outer surfaces wherein a diffuser hole passes through the component wall between the inner surface and the outer surface. The diffuser hole has a hole axis and includes: a metering section extending from an inlet at the inner surface to a junction plane between the inner and outer surfaces; and a diffuser section extending from the junction plane to an outlet at the outer surface, and increasing in flow area from the junction plane to the outlet, the diffuser section having an upstream portion defining a first area ratio and a downstream portion defining a second area ratio different from the second area ratio.

16. A turbine component having a component wall with inner and outer surfaces wherein a diffuser hole passes through the component wall between the inner surface and the outer surface, the diffuser hole having a hole axis and comprising:
-
a metering section extending from an inlet at the inner surface to a junction plane between the inner and outer surfaces; and a diffuser section extending from the junction plane to an outlet at the outer surface, and increasing in flow area from the junction plane to the outlet, the diffuser section having an upstream portion defining a first area ratio and a downstream portion defining a second area ratio different from the second area ratio; wherein the diffuser section is defined by an outer wall adjacent the outer surface, an inner wall adjacent the inner surface, and a pair of spaced-apart side walls extending between the inner and outer walls; the diffuser section includes a diffuser pedestal extending radially outwardly from the inner wall, so as to effectively divides the aft portion of the diffuser section into two separate legs. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
