A variable bleed valve includes a variable bleed valve door disposed in a bleed inlet in transition duct and rotatable about an axis at or near a forward end of door. Valve is operable to open and close a bleed slot open to a booster bleed flowpath located outwardly of transition duct and having an airflow restrictor. Airflow restrictor may be variable such as a flapper valve. Booster bleed flowpath may pass through a bifurcated bleed duct including an inner passage radially bound by spaced apart inner and middle bleed walls and an outer passage radially...


1. A gas turbine engine variable bleed apparatus comprising: a variable bleed valve including a variable bleed valve door disposed in a bleed inlet in a transition duct;a forward lip and an aft lip located at respective upstream and downstream ends of the variable bleed valve door, wherein the variable bleed valve door is pivotable or rotatable about an axis at a forward end of the variable bleed valve door,wherein the variable bleed valve is operable to open and close a bleed slot open to a plurality of bleed duct passages forming a booster bleed flowpa...
