  • Propeller-type propulsion system for an aircraft
    Patent number: 11572191
    Abstract: A propeller-type propulsion system for aircraft comprising a propeller, a plurality of electric motors and a gearbox. The gearbox has an output shaft onto which the propeller is mechanically coupled, and has an input shaft onto which the plurality of electric motors is mechanically coupled, the input shaft being off-center with respect to the output shaft. All of the electric motors are mechanically coupled one after the other along the input shaft such that the electric motors are at least partially integrated into a space, on the opposite side of the gearbox from the propeller, that is left free owing to the input shaft and the output shaft being off-center with respect to one another. As a result, the diameter of the propulsion system, in a plane perpendicular to the axis of rotation of the propeller, is reduced. This improves the aerodynamics and the fuel consumption of the aircraft.

  • Method for locating and repairing intermittent faults in communication structures of an aircraft
    Patent number: 11544165
    Abstract: To locate an intermittent fault in a communication structure of an aircraft comprising pieces of equipment that are interconnected by cabling forming a plurality of communication media that are shared, an analyzer retrieves an error report relating to transmission errors observed on each of said communication media, performs a count of the transmission errors, per type of error and per communication chain, computes a median of the counts for communication chains comprising the same pair of wired pieces of equipment, and when, for a communication chain, the count exceeds a threshold equal to the median plus a predefined margin, generates an alarm indicating detection of an intermittent fault in association with the communication chain that led the threshold to be exceeded. Thus, intermittent faults are easily located and repaired.
