Abstract: An aircraft propulsion system comprising a propeller, a plurality of electric motors, a transmission system configured to couple the electric motors to the propeller, and a propeller pitch adjustment system positioned at the rear of the transmission system. At least one of the electric motors is positioned in front of the transmission system. A connection structure is interposed between the propeller and the transmission system, the connection structure and the output shaft of the transmission system connected to the propeller being configured so that no electric motor positioned in front of the transmission system interferes with the propeller. Also an aircraft with such a system.

Abstract: An aircraft propulsion assembly including at least one first support that supports an electric propulsion system, at least one first attachment configured to connect the first support and a support structure of an aircraft, at least one second support distinct from and dissociated from the first support supporting a source of electrical energy configured to supply the electric propulsion system with electrical energy, as well as at least one second attachment configured to connect the second support and the support structure. An aircraft may include at least one such propulsion assembly. Given that the second support is distinct from and dissociated from the first support system, vibrations generated by the electric propulsion system are not transmitted to the source of electrical energy.

Abstract: An aircraft propulsion unit with an engine mount connecting a rigid casing, supporting a propeller, and a structure. First and second transverse link rods connect the casing and the structure with first and second joints each having an axis of pivoting substantially parallel to an axis of rotation of the propeller. First and second thrust rods connect the casing and the structure by first and second thrust rod connections. The first and second thrust rod connections separated from one another in the longitudinal direction. A longitudinal end stop is configured to limit the movement of the casing with respect to the structure in at least the longitudinal direction. An aircraft with at least one such propulsion unit.
