1. A gas turbine engine comprising:
a compressor section, a combustion section, a turbine section, and an exhaust section in serial flow order and together defining a core air flowpath;
a turbine rear frame extending through the core air flowpath at a location downstream of the turbine section, the turbine rear frame defining a leading edge within the core air flowpath; and
a waste heat recovery system operable to separate, at or upstream of the leading edge of the turbine rear frame, a core airflow exiting the turbine section into a primary exhaust airflow and a waste heat recovery airflow, the waste heat recovery system comprising:
a divider operable to define a primary exhaust flowpath and a waste heat recovery flowpath, wherein at least a portion of the divider is axially located corresponding to a leading edge of the turbine rear frame; and
a heat source exchanger positioned at least partially in the waste heat recovery flowpath to receive the waste heat recovery airflow.
