Abstract
A compressor air bleed assembly for a gas turbine engine includes a compressor casing surrounding a row of circumferentially spaced compressor blades and defining a flowpath for receiving compressor air flow compressed by the blades. The casing includes a bleed port disposed down stream of at least a row of the blades for receiving a portion of compressed air as bleed airflow. A bleed port, preferably in the form of an annular slot, extends away from the bleed port and has a first throat downstream of the port and a second throat downstream of the first throat. A first duct outlet in the duct leads to a first bleed air circuit, receives a first portion of the bleed airflow, and is disposed between the first and second throats. A second duct outlet in the duct leads to a second bleed air circuit, receives a second portion of the bleed circuit.
