Beschreibung
Zusammenfassung:	Gas turbine engine compressor bleed assembly includes annular bleed plenum between annular outer and inner casings circumscribing compressor flowpath of compressor, upstream and downstream bleed ports disposed through inner casing and between compressor flowpath and plenum at upstream and downstream stages. Bleed path extends from downstream bleed port through bleed plenum and out bleed outlet disposed through outer casing. Autonomously actuated valve such as poppet valve disposed in bleed path or downstream bleed port. Autonomously actuated or poppet valve may be set to open at take-off and/or climb. Bleed outlet may be customer and domestic or engine bleed outlet disposed through outer casing and in fluid bleed air communication with bleed plenum. Another assembly may include annular forward and aft bleed outlets connected to plenums. Bleed path extends from downstream bleed port through plenums and out forward bleed outlet.
