Abstract
A fan module for an aircraft is disclosed herein. The fan module includes a fan rotor, a vane ring, and an optional power supply system. The fan rotor is configured to discharge thrust in an aft direction when rotated about a central axis. The vane ring is located aft of the fan rotor along the central axis and mounted for rotation about the central axis. The vane ring includes a plurality of airfoils arranged to interact with the thrust discharged by the fan rotor so that the thrust drives rotation of the vane ring.
