Abstract
A gas turbine engine includes a compressor section, a combustor section and a turbine section, all arranged about a central axis. A turbine rotor drives a driveshaft for rotation on the central axis. The driveshaft in turn drives at least two fan rotors on axes parallel to, but spaced from, the central axis. The fan rotors each deliver a portion of the air they move into a central inlet for delivering the air to the compressor section. In addition, the majority of the air moved by the plurality of fan rotors passes between a cowl and an outer periphery of a housing for the central core of the engine. This bypass air provides propulsion as is known in the turbojet art.
