Abstract
A gas turbine engine includes a turbomachine defining an engine inlet to an inlet duct, a fan duct inlet to a fan duct, and a core inlet to a core duct; a primary fan driven by the turbomachine; a nacelle surrounding the primary fan; and a secondary fan located downstream of the primary fan within the inlet duct. The gas turbine engine is characterized by a thrust to power airflow ratio, a core bypass ratio, a blade effective acoustic length, an acoustic spacing length, and an inlet-to-nacelle ratio.
