Abstract

Methods and systems for a gas turbine engine (100; 200) comprising a modulated bleed valve (360) are provided. The gas turbine engine (100; 200; 400) may comprise a turbine nozzle (285) coupled to a controller (350), a modulated bleed valve (360) in communication with the controller (350), and a tangible, non-transitory memory providing instructions to the controller (350) to perform operations. The operations may include receiving parameter values (371, 372, 373) from the parameter sensor (370) at various times, determining desired bleed airflows to flow through the modulated bleed valve (360) at various times, and/or commanding the modulated bleed valve (360) to assume an open configuration or a closed configuration at various times. The modulated bleed valve (360) may be configured to allow bleed airflow (340) to bypass a nozzle choke area (286; 386) of the turbine nozzle (285) and join a nozzle airflow (225; 325).
