1. An electrically powered fan engine including:
an energiser chamber between an inlet and an exhaust of the electrically powered fan engine;
a first rotor within the energiser chamber, the first rotor including a plurality of blades and being configured to receive a fluid from the inlet and configured to rotate at a first velocity; and
a second rotor within the energiser chamber, the second rotor including a plurality of blades and being configured to receive the fluid after passing through the first rotor and configured to rotate at a second velocity,
wherein the first velocity is different from the second velocity,
wherein the first rotor includes a rim and the second rotor includes a rim,
wherein the electrically powered fan engine further comprises a first electromagnetic circuit configured to drive the rim of the first rotor and a second electromagnetic circuit configured to drive the rim of the second rotor,
wherein the electrically powered fan engine further comprises a by-pass duct extending between a by-pass inlet and a by-pass outlet, wherein the by-pass inlet is positioned upstream of the first rotor, and wherein the by-pass outlet is positioned in the exhaust nozzle, and
wherein the first electromagnetic circuit and the second electromagnetic circuit are each provided within the by-pass duct for cooling, in-use.
