Abstract
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 a wall of the separator within the inlet flow path.
Claims17
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;
- and
- one or more grooves disposed on at least a portion of said wall surface.

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;
- and
- one 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;
- and
- wherein 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.
5 more elements
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;
- and
- a plurality of grooves disposed within said inlet flow path on at least one of said outer circumferential surface and said inner circumferential surface.
