Abstract
A rotating component of a turbine engine is provided and includes a wheel having a face to which fluid flow is provided and a plurality of impeller vanes forming a plurality of grooves along which the fluid flow is directed from an outer to an inner diameter of the wheel face, at least one of the plurality of the impeller vanes including a radially inwardly facing vane surface formed to define a cutaway portion.
Claims20
A rotating component of a turbine engine, comprising:
- a wheel having a face to which fluid flow is provided;
- and
- a plurality of impeller vanes forming a plurality of grooves along which the fluid flow is directed from an outer to an inner diameter of the wheel face,
- at least one of the plurality of the impeller vanes including a radially inwardly facing vane surface formed to define a cutaway portion.
A rotating component of a turbine engine, comprising:
- a wheel, which is rotatable about a rotational axis, having a face to which fluid flow is provided;
- and
- a plurality of impeller vanes protruding axially from the wheel face to form a plurality of grooves between adjacent ones of the plurality of impeller vanes along which the fluid flow is directed from an outer to an inner diameter of the wheel face,
- at least one of the plurality of the impeller vanes including an inner diameter portion at which a vane surface faces radially inwardly, the vane surface being formed to define a cutaway portion.
A method of forming a rotating component of a turbine engine, comprising:
- fashioning a wheel having a face to which fluid flow is provided;
- and
- forming on the wheel face a plurality of grooves along which the secondary flow is directed from an outer to an inner diameter of the wheel face;
- and
- machining a cutaway portion at a radially inwardly facing vane surface of at least one of the plurality of the impeller vanes.
