Abstract
A method and apparatus for minimizing engine weight for a turbine engine by utilizing one or more discrete protuberances disposed on an engine component wall. The wall can have a nominal thickness to decrease engine weight while the protuberances can provide increased discrete thicknesses for providing one or more cooling holes. The increased thickness at the protuberances provides for an increased thickness to provide sufficient length to increase cooling hole effectiveness.
Claims20
An airfoil comprising:
- an exterior wall having an interior surface and an exterior surface, the interior surface at least partially defining an interior of the airfoil;
- a protuberance formed along the interior surface and extending into the interior, with the protuberance extending a height from the interior surface, the height being a distance perpendicular to the interior surface at the protuberance;
- a film hole extending along a centerline through the exterior wall between an inlet and an outlet, the inlet provided within a portion of the protuberance and the outlet provided along a portion of the exterior surface;
- and
- a concave recess provided entirely along a portion of the protuberance, with the inlet being provided along a portion of the concave recess.

- a protuberance formed along the interior surface and extending into the interior, with the protuberance extending a height from the interior surface, the height being a distance perpendicular to the interior surface at the protuberance;
- a film hole extending along a centerline through the exterior wall between an inlet and an outlet, the inlet provided along a portion of the protuberance and the outlet provided along a portion of the exterior surface, the film hole extending a length along the centerline, with the height being greater than or equal to 30% of the length;
- and
- a concave recess defined in a portion of the protuberance, wherein the inlet is defined in a portion of the concave recess.
