Abstract: A propulsion system for an electric vehicle includes a first electric propulsion motor including a stator and a rotor that has a first and second output shafts that are axially opposed and define first and second torque outputs of the first electric motor. The system also includes a second electric propulsion motor including a stator and a rotor having a second output shaft with a torque output. Further, the system includes a first reduction gearbox to receive the torque supplied on the first torque output of the first electric motor where appropriate via a first selective or non-selective coupling system, a second reduction gearbox to receive the torque supplied by the second electric motor where appropriate via a second selective or non-selective coupling system, and a third coupling system for coupling the second torque output of the first electric motor to the torque output of the second electric motor.

Abstract: A system for automatically updating an airport database relating to an airport includes an assembly of information sources installed on an aircraft for generating information and notably images of the airport when the aircraft is travelling over or above the airport, and units for processing this information and for correcting data from the airport database in the case where at least one difference is detected between the information generated and the data contained in the airport database, the system thus being capable of automatically updating the airport database each time that an aircraft able to generate and to collect information is taxiing over the airport and/or flying above the airport such that the data available in the airport database is recent and reliable.

Abstract: A method for assisting the braking of an aircraft on a runway comprises the steps implemented automatically, including: before the landing of the aircraft on the runway, receiving the input, by a crew member of the aircraft, of a target braking distance by a man-machine interface associated with a processing unit, the target braking distance corresponding to a distance between a threshold of the runway and a selected exit of the runway; engaging an automatic optimized braking mode of the aircraft making it possible for the aircraft to attain the target speed when it reaches the selected runway exit; and—controlling a braking system of the aircraft, while the aircraft is running on the runway, according to this automatic optimized braking mode.

Abstract: Extended and integrated aeronautical safety and surveillance system comprising first means adapted for preventing in-flight collisions between aircraft (“TCAS”) second means for carrying out a function from among the surveillance and air traffic control functions (“ADS-B”). The system also comprises third means for carrying out at least one function from among a set of ground movements assistance functions comprising in particular a function for displaying a map during the movement of an aircraft in an airport. Finally the system is characterized in that the first, second and third means are embedded on one and the same hardware platform.

Abstract: A method for assisting in the locating of a first aircraft includes a step of emission by the first aircraft of an identifier and of a time-stamped position reading, said method further including: the reception and the storage by at least one second aircraft of the identifier and of the time-stamped position reading, and the downloading by the second aircraft, after its landing, of the identifiers and of the time-stamped position readings to a database on the ground, and, in case of disappearance of the first aircraft, the determination of the last known position of the first aircraft based on the time-stamped position readings stored in the database on the ground.
