Abstract

A thermal management system for a gas turbine engine includes a first heat exchanger that provides a first conditioned fluid, a second heat exchanger in series flow communication with the first heat exchanger and that exchanges heat with the first conditioned fluid to provide a second conditioned fluid, and a third heat exchanger in parallel flow communication with the second heat exchanger and that selectively exchanges heat with the first conditioned fluid to provide a third conditioned fluid. The second conditioned fluid and the third conditioned fluid combine to provide a mixed conditioned fluid. A first portion of the mixed conditioned fluid including a first temperature is communicated to a first engine system. A second portion of the mixed conditioned fluid including a second temperature is communicated to a second engine system. The second temperature includes a greater temperature than the first temperature.
