Variable bleed valve door assembly and system for gas turbine engines

Abstract:

A variable bleed valve system for use in a turbofan engine includes a plurality of circumferentially spaced variable bleed valve assemblies. Each variable bleed valve assembly includes a plurality of circumferentially spaced variable bleed valve assemblies. Each variable bleed valve assembly includes a variable bleed valve door that is selectively adjustable through a range of intermediate positions between a closed position and an open position. The variable bleed valve door is configured to maintain any of the intermediate positions. Each variable bleed valve assembly also includes an actuator operatively coupled to the variable bleed valve door. The actuator is configured to selectively adjust a position of the variable bleed valve door through the range of intermediate positions between the closed position and the open position.
