Abstract
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.
Claims20
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;
- and
- at least one contiguous heat exchanger having a cold side inlet surface receiving a cold-side airflow;
- wherein the at least one contiguous heat exchanger is 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.
An engine, comprising:
- an enclosure surrounding an engine having an engine centerline, and the enclosure defining a passage for a cold-side airflow;
- at least one contiguous heat exchanger having a cold side inlet surface receiving the cold-side airflow along a vector having a radial or tangential component relative to an engine centerline;
- and
- a variable flow control mechanism for redirecting the cold-side airflow through the at least one contiguous heat exchanger;
- wherein the at least one contiguous heat exchanger is 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.
A process for cooling a heat load within an engine, comprising:
- directing a cold-side airflow through a passage defined by an engine air duct;
- and
- directing the cold-side airflow through a cold side inlet surface of at least one contiguous heat exchanger disposed within the passage such that a surface normal relative to the cold side inlet surface is offset by at least 30 degrees from an engine centerline.
