Patent ID: 8516791

Claim:
A method of assembling a gas turbine engine, said method comprising: providing at least one heat exchanger assembly including a heat exchanger and a mixer coupled to the at least one heat exchanger and extending downstream from the heat exchanger, wherein the at least one heat exchanger includes an inlet and the mixer includes an inlet that is substantially coaxially aligned with the inlet of the at least one heat exchanger, and wherein the mixer includes a plurality of windows formed therein; and coupling the at least one heat exchanger assembly within a bypass duct of the engine such that a first portion of bypass air flows above and below the at least one heat exchanger assembly and mixer within the bypass duct, while a second portion of bypass air flows through the at least one heat exchanger, wherein the first and second portions of bypass air communicate at the plurality of windows of the mixer, wherein the at least one heat exchanger assembly is coupled to at least one of an outer engine casing and an inner engine casing of the turbine engine.
