Abstract
A gas turbine engine system includes a fan bypass passage in a cooling passage having an inlet that receives a bleed flow from the fan bypass passage and an outlet that discharges the bleed flow into the fan bypass passage. A nozzle having a variable cross-sectional area controls an airflow within the fan bypass passage. The bleed flow outlet is placed such that moving the nozzle to change the variable cross-sectional area controls an amount of the bleed flow through the cooling passage.
