Francois Bommier 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).

  • Patent number: 7996118
    Abstract: An aircraft device includes a rudder, a control unit that applies a deflection instruction to the rudder, a measuring section that measures a recovery characteristic of aircraft movement in response to the rudder deflection instruction, a recorder that records an applied deflection instruction and a corresponding recovery characteristic, and a servo-control that maintains the recovery characteristic. The control unit receives a recovery instruction for a recovery characteristic, which is identifiable for an aerodynamic effect, and generates the rudder deflection instruction induced by the recovery instruction.

  • Patent number: 7523657
    Abstract: A device for measuring air turbulence in the surroundings of an aircraft includes a measurement system having lidars which are mounted on the aircraft and which are intended to carry out, during a flight of the aircraft, twelve measurements of aerodynamic velocity in the environment surrounding the aircraft. The measurement system carries out the twelve measurements at four different measurement points, each time according to three predetermined axes. A central unit which, with the aid of the aerodynamic velocity measurements and of a first order predetermined mathematical model describing an aerodynamic velocity field as a function of twelve variables, determines an aerodynamic velocity field which exists in the environment of the aircraft and which is representative of the air turbulence.

  • Publication number: 20080249670
    Abstract: The inventive device (1) comprises at least one rudder (2A, 2B, 2n), a control unit (4) for applying a deflexion instruction to the rudder, means (6) for measuring recovery characteristic displaying the evolution of the aircraft movement in the response to said rudder deflexion instruction, means (7) for recording at least one applied deflexion instruction and a corresponding recovery characteristic, a servo-control means (13) for triggering the aircraft in such a way that the recovery characteristic is maintained, wherein the control unit (4) is provided with means (10) for receiving an recovery instruction which makes it possible to obtain a recovery characteristic which is identifiable for at least one aerodynamic effect and means (11) generating the rudder deflexion instruction induced by the recovery instruction.

  • Publication number: 20080190192
    Abstract: The invention concerns a method and a device for measuring air turbulence in the an aircraft. The device (1) comprises a measuring system (2) including lidars (L1, L2, L3, L4) which are mounted on the aircraft and which are designed to produce during the flight of the aircraft twelve air speed measurements in the surroundings outside the aircraft, said measuring system (2) producing said twelve measurements in four different measuring points, each time along three predetermined axes, and a central unit (3), which, by means of the measurements produced by said measuring system (2) and a predetermined mathematical model of the first order describing a field of air speeds based on twelve variables, determines a field of air speeds which exist in said aircraft surroundings, and which represents said air turbulence.
