One embodiment of an engine may include an enclosure surrounding an engine having an engine centerline, and the enclosure defining a passage for a cold-side airflow. The engine may also include one or more contiguous heat exchangers having a cold side inlet surface receiving a cold-side airflow. The heat exchanger may be disposed within the passage, such that a surface normal relative to the cold side inlet surface is offset by at least 30 degrees from the engine centerline.
1. A gas turbine engine, comprising: an engine including an engine centerline and a passage being one of a fan bypass duct, a third stream duct and a ram air duct;at least one contiguous heat exchanger having a cold-side inlet surface receiving a cold-side airflow; andat least one of: a ring slidably coupled to one of an inner diameter and an outer diameter of the passage, ora forward-facing scoop disposed within the passage;wherein the at least one contiguous heat exchanger is disposed within the passage such that a surface normal relative to the cold-s...
