Abstract

A gas turbine engine system including a plurality of bleed off doors forming a portion of a conical surface in the flow path between the low pressure compressor and the intermediate pressure compressor. A plurality of actuators are coupled to a unison ring and move the unison ring in a substantially axial direction. The plurality of bleed off doors are coupled to the unison ring and move therewith.
