Embodiments of the present invention provide an inlet particle separator for a gas turbine engine having an inlet flow path, a scavenge flow path, a core flow path, and a flow splitter disposed between the scavenge and core flow paths. A plurality of grooves may be disposed about an inner surface of

대표청구항 ▼

1. A particle separator comprising: a first end and an opposed second end;an inlet flow path adjacent to said first end, a scavenge flow path adjacent to said second end, and a core flow path adjacent to said second end;a radially outward wall surface at least partially defining said inlet flow path; andone or more grooves disposed on at least a portion of said wall surface. 2. The particle separator of claim 1, wherein each of said one or more grooves are axially disposed along a length of said inlet flow path. 3. The particle separator of claim 1, wherein each of said one or more grooves comprises a shrouded sidewall and an exposed sidewall. 4. The particle separator of claim 3, wherein said shrouded sidewall at least partially conceals a root of said groove, wherein said root is connected to both of said shrouded sidewall and said exposed sidewall. 5. The particle separator of claim 3, wherein at least one of said shrouded sidewall and said exposed sidewall have a non-linear profile. 6. The particle separator of claim 5, wherein said non-linear profile varies along said length. 7. The particle separator of claim 1, wherein said one or more grooves comprise a base dimension and a height dimension, wherein there is a ratio between said base dimension and said height dimension, and wherein said ratio varies along a length of said one or more grooves. 8. The particle separator of claim 1, wherein said inlet flow path is annular. 9. The particle separator of claim 1, wherein said inlet flow path is non-annular. 10. A particle separator comprising: a first end and an opposed second end;a first wall surface and a second wall surface, wherein said first wall surface extends from said first end to said second end and wherein said second wall surface is adjacent said first end;an inlet flow path adjacent said first end, a scavenge flow path adjacent to said second end, and a core flow path adjacent to said second end;a splitter disposed between said scavenge flow path and said core flow path; andone or more grooves disposed within said inlet flow path and on said first wall surface which defines at least in part a radially outer boundary of said inlet flow path; andwherein said inlet flow path is defined at least partially by a portion of said first wall surface and at least partially by a portion of said second wall surface. 11. The particle separator of claim 10, wherein each of said one or more grooves are axially disposed along a length of said inlet flow path. 12. The particle separator of claim 10, wherein each of said one or more grooves comprises sidewalls having non-linear profiles. 13. The particle separator of claim 10, wherein said inlet flow path is annular. 14. The particle separator of claim 10, wherein said inlet flow path is non-annular. 15. A particle separator comprising: a longitudinal axis therethrough;a generally annular inlet flow path defined at least in part by an outer circumferential surface and an inner circumferential surface;a generally annular scavenge flow path, and a generally annular core flow path;a generally circumferential splitter disposed between said scavenge flow path and said core flow path; anda plurality of grooves disposed within said inlet flow path on at least one of said outer circumferential surface and said inner circumferential surface. 16. The particle separator of claim 15, wherein each of said one or more grooves are axially disposed. 17. The particle separator of claim 15, wherein each of said one or more grooves are axially disposed in an array on said outer circumferential surface.
