1. A turbine engine assembly comprising:
a compressor section where an inlet airflow is compressed;
a combustor section where the compressed inlet airflow is mixed with fuel and ignited to generate an exhaust gas flow that is communicated through a core flow path;
a turbine section through which the exhaust gas flow expands to generate a mechanical power output;
a condenser at least partially disposed within the core flow path where water is extracted from the exhaust gas flow;
an evaporator system at least partially disposed within the core flow path upstream of the condenser where thermal energy from the exhaust gas flow is utilized to generate a steam flow from at least a portion of water extracted by the condenser for injection into a core flow path; and
an aftercooler where a cooling flow is selectively injected into the core flow path downstream of the turbine section and upstream of at least the condenser for cooling the exhaust gas flow in response to a parameter indicative of an engine operating parameter exceeding a predefined condition.
