Abstract
A gas turbine engine component that has a web provided with an array of cooling holes distributed with respect to a first direction, wherein the cooling holes have a cross-sectional shape that varies along the first direction. The component may be configured so that the first direction corresponds to a loading distribution of the component which increases along the first direction from a low loading position to a high loading position.
Claims20
A gas turbine engine component comprising:
- a web provided with an array of cooling holes distributed adjacent to each other with respect to a first direction, wherein the cooling holes have a cross-sectional shape that varies from one cooling hole in the array to another along the first direction;
- and wherein an edge fillet radius varies from one cooling hole in the array to another along the first direction.
A gas turbine engine component comprising:
- a web provided with an array of cooling holes distributed adjacent to each other with respect to a first direction, wherein the cooling holes have a cross-sectional shape that varies from one cooling hole in the array to another along the first direction;
- and wherein an edge chamfer length on a face of the web varies from one cooling hole in the array to another along the first direction.
A gas turbine engine component comprising:
- a web provided with an array of cooling holes distributed adjacent to each other with respect to a first direction, wherein the cooling holes have a cross-sectional shape that varies from one cooling hole in the array to another along the first direction;
- wherein
- a relative thickness of any hole reinforcement features projecting from one or more respective faces of the web around the cooling hole, relative to a local web thickness varies from one cooling hole in the array to another along the first direction;
- an offset angle between a hole axis along which the cooling hole extends and a normal axis which is normal to a face of the web varies from one cooling hole in the array to another along the first direction;
- and
- wherein along the first direction, the relative thickness of any hole reinforcement features increases as the offset angle increases, or the relative thickness of any hole reinforcement features decreases as the offset angle decreases.
