Abstract: A flange arrangement of a gas turbine engine includes a first flange of a first component, and a second flange of a second component axially offset from the first flange along an engine central longitudinal axis. The first flange is secured to the second flange. One or more flange flowpaths are defined between the first flange and the second flange to convey a flange airflow from an interior of the second component thereby thermally conditioning the flange arrangement. The flange airflow is driven through the one or more flange flowpaths by a pressure differential.
