Abstract
Retention assemblies and retention assembly cooling methods are provided. An exemplary retention assembly comprises an annular baffle, an annular attachment bracket comprising a gas turbine engine component, and first and second cooling passages defined by the baffle and attachment bracket. The first cooling passage is configured to receive a first airflow and the second cooling passage is configured to receive a second airflow. The first airflow has a lower pressure than the second airflow. An exemplary method comprises flowing a first airflow to a first cooling passage defined by a baffle and an attachment bracket of a retention assembly, and flowing a second airflow to a second cooling passage defined by the baffle and the attachment bracket. The second cooling passage is separate from the first cooling passage. The first airflow cools radially outward structures of the retention assembly, and the attachment bracket comprises a CMC component.
