Abstract
A high flow interstage air extraction system for a gas turbine engine includes a 360 degree annular slot formed in a compressor stator casing by a first wall and a second wall. A plurality of baffle plates extend from the second wall to eliminate circumferential airflow. A plurality of stator vane platforms form at least a portion of the first wall. The annular slot results in large amounts of interstage compressor air being extracted from the compressor without adding length to the compressor and the engine.
