  • Gas turbine engine hybrid variable bleed valve
    Patent number: 10287992
    Abstract: A hybrid variable bleed valve includes a static bleed slot disposed in a transition duct defining a flow path for a core air flow, a variable bleed valve door disposed radially outwardly of the transition duct and the static bleed slot, a radially inward bleed cavity defined radially outwardly of the transition duct and radially inward of the variable bleed valve door for collection of a plurality of particulates and a pressure recovery return duct in fluid communication with the radially inward cavity and the transition duct. The hybrid variable bleed valve apparatus operable to open and close the variable bleed valve door to a booster bleed flow, flowing radially outwardly from the static bleed slot, for extraction of the particulates and provide a pressure recovery flow into the core air flow via the pressure recovery return duct. The hybrid variable bleed valve configured for use in a gas turbine engine.
