    Abstract: A gas turbine engine has a nose cone with a nose cone upstream end and an inlet housing including a plurality of separate flow paths at a housing upstream end which is downstream of the nose cone upstream end. The inlet housing includes a mixing portion downstream of the housing upstream end which mixes airflow from the separate flow paths, such that the airflow is generally around 360 degrees of a rotational axis of the gas turbine engine. A rotor and a turbine drive a shaft to drive the rotor with the shaft including a bearing mounted at a location downstream of the nose cone upstream end.

    Abstract: Embodiments of a Gas Turbine Engine ("GTE (20)") are provided, as are embodiments of a plasma flow-controlled intake system (22) for deployment on a GTE. In one embodiment, the GTE includes a turbine section (30), a combustion section (28) upstream of the turbine section, a compressor section (26) upstream of the combustion section, and intake section (24) upstream of the compressor section. The intake section includes a plenum (38), a first inlet (34) fluidly coupled to the plenum, and a flow-obstructing structure (48) projecting into the plenum and having an outer surface impinged by the airflow directed into the plenum through the first inlet during operation of the GTE. A first array of plasma actuators (82, 128) is disposed on flow-obstructing structure and, when activated, suppresses vortex shedding of the air flowing over the outer surface of the flow-obstructing structure.
