Machined film holes
First Claim
1. A component comprising a set of thin film cooling holes formed therein,wherein each of the thin film cooling holes provides a passage between a first surface of the component and a second surface of the component, andwherein each of the thin film cooling holes includes:
- a smooth transition between the first surface of the component and the surface the passage;
a progressively steeper flow path relative to the first surface of the component and between the smooth transition and the second surface of the component;
a lip opposing the smooth transition at the interface between the first surface of the component and the passage; and
an edge break at the lip on the first surface of the component.

9. A component comprising a set of thin film cooling holes formed therein,
wherein each of the thin film cooling holes provides a passage between a first surface of the component and a second surface of the component, wherein the passage enters the first surface of the component at a non-perpendicular angle to form an overhang over the passage at a lip on one side of the interface between the passage and the first surface of the component, and wherein the passage includes an edge break at the overhang on the first surface of the component.

15. A method of manufacturing an array of thin film cooling holes in a component, the method comprising:
-
inspecting the component to obtain a component surface data set; determining machining paths for each of the thin film cooling holes in the array of thin film cooling holes based on the component surface data set; and for each of the thin film cooling holes, machining a passage between a first surface of the component and a second surface of the component, wherein machining the passage includes; machining a smooth transition between the first surface of the component and the surface the passage, machining a progressively steeper flow path relative to the first surface of the component and between the smooth transition and the second surface of the component, and machining an edge break at a lip opposing the smooth transition at the interface between the first surface of the component and the passage. - View Dependent Claims (16, 17, 18, 19)
