Abstract
A component for a gas turbine engine including a gas path wall having a first surface and a second surface. A cooling hole extends through the gas path wall from an inlet in the first surface through a transition to an outlet in the second surface. Cusps are formed on the transition.
Claims14
A component for a gas turbine engine, the component comprising:
- a gas path wall having a first surface and a second surface;
- a cooling hole extending through the gas path wall from an inlet in the first surface through a transition to an outlet in the second surface, wherein a first cross sectional area of the cooling hole does not increase from the inlet to the transition, and wherein a second cross sectional area of the cooling hole increases from the transition to the outlet;
- and
- cusps formed on the transition, wherein only one cusp extends from the transition along a ridge, the ridge extending from the transition toward a trailing edge of the outlet.

A cooling system for a gas turbine engine component, the cooling system comprising:
- a flow path wall having a first surface exposed to cooling fluid and a second surface exposed to working fluid flow;
- a cooling hole extending through the flow path wall from an inlet in the first surface through a transition to an outlet in the second surface;
- a metering section extending from the inlet to the transition;
- at least two longitudinal cusps extending along the metering section from the inlet toward the transition, wherein the longitudinal cusps divide the metering section into lobes;
- and
- a diffusing section extending from the transition to the outlet, wherein only longitudinal cusp extends from the transition along a longitudinal ridge, the longitudinal ridge dividing the diffusing section into lobes.
