Abstract:
1. A gas turbine engine, comprising: a fan; a geared architecture for driving the fan; a turbine section for driving the geared architecture; a thermal management system that includes a first fluid circuit and a second fluid circuit that manages heat generated in at least a portion of the gas turbine engine; a first heat exchanger incorporated into each of said first fluid circuit and said second fluid circuit; a second heat exchanger incorporated into said first fluid circuit; a valve that controls a amount of a first fluid that is communicated to said first heat exchanger and said second amount of the first fluid to said heat exchanger, wherein said valve is disposed upstream of said first heat exchanger and said second heat exchanger; a fluid passage within said first fluid circuit that bypasses a portion of the first fluid from both said first heat exchanger and said second heat exchanger to be mixed with a portion which has gone through at least one of said first heat exchanger and said second heat exchanger; and a controller that controls positioning of said valve, wherein said first amount of said first fluid communicated to said first heat exchanger is based on a first characteristic of a second fluid and said second amount of said first fluid communicated to said second heat exchanger is based on a second characteristic of said second fluid.
