Patent ID: 7797945

Claim:
A bleed valve assembly for discharging bleed air into a gas turbine engine bypass plenum having bypass air flowing there-through in a first flow direction, the valve assembly comprising: a bleed flow duct having bleed air inlet and a bleed air outlet, the bleed air inlet adapted to receive bleed air from a turbine engine compressor, the bleed air outlet configured to discharge the bleed air into the bypass plenum; a bleed valve disposed at least partially within the bleed flow duct and movable between at least a closed position, in which the bleed air does not flow through the bleed flow duct, and an open position, in which the bleed air flows through the bleed flow duct; and a flow deflector disposed adjacent the bleed air outlet, the flow deflector having a plurality of openings formed therein, each opening symmetrically disposed about a central axis and including an inlet port in fluid communication with the bleed air flow passage and an outlet port in fluid communication with the bypass plenum, each opening further oriented at a discharge angle, wherein: the plurality of openings includes a first set of openings and a second set of openings, the first set of openings at least partially surrounding the second set of openings, the discharge angle of each opening is an angle relative to a first plane that is tangent to the outlet port of the opening and intersects the central axis of the opening, the discharge angle of each of the first set of openings is substantially perpendicular to the first plane, and the discharge angle of each of the second set of openings is such that bleed air is discharged therefrom in a direction that does not have a vector component in the first flow direction.
