Bleed valve outlet flow deflector

摘要

A bleed valve assembly for discharging bleed air into a gas turbine engine bypass plenum (116) includes a bleed flow duct (202), a bleed valve (204), and a flow deflector (206). The bleed flow duct (202) is contoured such that it delivers uniformly flowing bleed air to the flow deflector (206) when the bleed valve (204) is in the open position. The flow deflector (206) has a plurality of openings (218-1, 218-2) formed therein. Each opening (218-1, 218-2) fluidly communicates the bleed air flow passage with the bypass plenum (116). A portion of the openings (218) are oriented at a discharge angle such that bleed air is discharged from each opening (218-1, 218-2) in a direction that does not have a vector component in the direction in which air is flowing in the bypass plenum (116), and another portion of the openings (218) are oriented to provide stress relief to the deflector (206).
