Abstract: An engine assembly with an electric motor that includes a cooling system of which a heat sink portion is arranged in an exhaust cone downstream of the fan driven by the electric motor, that is designed to effect thermal exchanges with a wall of the exhaust cone. Such an electric rear fan arrangement with boundary layer ingestion enables a cold air flow coming from the fan when the engine assembly is in operation to be used to cool the different components of the engine assembly.

Abstract: An aircraft propulsion assembly including a fan. It include a first engine and a second engine which are not coaxial and a mechanical energy transmission device configured to enable the fan to be conjointly rotated by the first engine and the second engine. This allows an aircraft propulsion assembly to be produced of which the fan may be positioned so as to ingest the boundary layer formed at the surface of a member of the aircraft equipped with the propulsion assembly, while allowing operating modes in the case of certain failures, and certification for commercial use of an aircraft equipped with such a propulsion assembly, to which the invention also relates.
