Abstract
An aircraft propulsion plant including an electric motor having a rotor and a stator mechanically linked to a base which can be mounted at the rear of an aircraft fuselage, a fan rotated by the rotor, a set of fixed blades located downstream of the fan, and a nacelle comprising an outer casing and a fan casing surrounding the fan and the set of fixed blades. The nacelle is mechanically linked to the base through the set of fixed blades. This configuration enables a cooling circuit to be formed for enabling the heat produced by the electric motor at the location of the stator to be evacuated towards the fixed blades and the nacelle where it is dissipated. Furthermore, this heat may be used for the de-icing of the nacelle lip.
