Abstract: A gas turbine engine has a fan and a compressor section with a first lower pressure location and a second higher pressure location. A heat exchanger and a higher pressure tap from the second higher pressure location pass through the heat exchanger. Air in the higher pressure tap is cooled by air from a lower pressure tap from the first lower pressure location. A valve controls flow to the heat exchanger from the lower pressure tap, the valve being controlled to limit flow from the lower pressure tap under certain conditions.

Abstract: A heat exchanger has a first plurality of passages extending in a first direction and to receive a first fluid and a second plurality of passages extending in a second direction, and to receive a second fluid, and the first plurality of passages being formed across a cross-sectional face of the heat exchanger, and there being distinct combined flow cross-sectional areas of the first plurality of passages in different locations across the cross-sectional face of the heat exchanger. A gas turbine engine and a method of forming a heat exchanger are also disclosed.

Abstract: A heat exchanger has a first plurality of fluid passages with an inlet manifold communicating into a core portion, and then an outlet manifold. A second plurality of fluid passages has an inlet manifold communicating into a core portion, and then into an outlet manifold and the core portions of both the first and second pluralities of fluid passages having smaller cross-sectional areas than cross-sectional areas of the inlet and outlet manifolds. A gas turbine engine and a method of forming a heat exchanger are also disclosed.
