1. An electric motor nacelle for a vertical take-off and landing aircraft comprising:
a fairing wherein an electric motor is housed equipped with at least one propeller extending outwards from a top face of the fairing, and
a cooling device designed to cool the electric motor when the aircraft is in take-off, cruise and landing phases and comprising a reversible coolant fluid supply and exhaust manifold, adapted, alternately:
in the cruise phase, to receive a stream of cold fluid generated by the movement of the aircraft and to convey said stream of fluid, through the motor, towards an outlet situated opposite the propeller, and
in the take-off or landing phase, to receive a stream of cooling fluid transmitted by the propeller and having passed through the motor, the stream of fluid being heated by contact with heat exchange surfaces of said motor.
