ASYMMETRIC FLOW EXTRACTION SYSTEM

A system for asymmetric flow extraction is described and claimed, the system comprising a flow path (17), a bleed slot (219) in the flow path (17), a bleed cavity (200) for receiving at least a portion of the fluid extracted from the flow path (17) and a bleed passage (100) in flow communication wit...

Beschreibung
Zusammenfassung:	A system for asymmetric flow extraction is described and claimed, the system comprising a flow path (17), a bleed slot (219) in the flow path (17), a bleed cavity (200) for receiving at least a portion of the fluid extracted from the flow path (17) and a bleed passage (100) in flow communication with the bleed slot (219) and the bleed cavity (200) wherein the bleed passage (100) has at least one deflector (151) having a shape such that the width of the bleed passage cross section varies in a direction normal to the direction of fluid flow in the bleed passage (100). In another embodiment, the deflector (151) has an aerodynamic surface (175) having a shape such that the flow passage between the aerodynamic surface (175) and a surface (505) located away from it has a cross sectional shape that is non-axisymmetric. In another embodiment, the bleed passage (100) comprises an assembly of a plurality deflectors (151), arranged circumferentially.
