Patents by Inventor Alexandre Gentilhomme

Alexandre Gentilhomme has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • More electric flight control system onboard an aircraft
    Patent number: 8740155
    Abstract: An electric flight control system onboard an aircraft provided with flight control surfaces and controllers for controlling these surfaces, that include at least one local electro-hydraulic generator to supply hydraulic servocontrols connected to flight control surfaces.
    Type: Grant
    Filed: January 4, 2010
    Date of Patent: June 3, 2014
    Assignee: Airbus Operations SAS
    Inventors: Marc Fervel, Alexandre Gentilhomme
  • Flight control system for an aircraft
    Patent number: 8430354
    Abstract: Power takeoff means (46, 47, 60, 61) for this flight control system adjacent to the aircraft engines (41, 42) are all-electric and this makes it possible to reduce the length of hydraulic connections leading to actuators of the controlled devices (54, 55, 66). Electrical generators are of different types to minimize the risk of a generic failure. Characteristically of the invention, some generators (60, 61) have a constant voltage to frequency ratio and directly or almost directly control electro-hydraulic pumps (64, 65), without modifying the current characteristic and with no power electronics. Furthermore, system reconfigurations are made possible by additional electrical connections (69, 70, 71, 72) in case of failure.

  • MORE ELECTRIC FLIGHT CONTROL SYSTEM ONBOARD AN AIRCRAFT
    Publication number: 20100170999
    Abstract: The invention relates to a more electric flight control system onboard an aircraft provided with flight control surfaces and means of controlling these surfaces, that comprises at least one local electro-hydraulic generator (HPP1, HPP2) to supply hydraulic servocontrols (34) connected to flight control surfaces (31, 32, 33).
