  • Control device for an engine
    Patent number: 9745051
    Abstract: An engine control device having a calculator for calculating a pitch setpoint for at least one propeller of the engine, the calculator taking account at least of a flight speed.
    Type: Grant
    Filed: November 15, 2013
    Date of Patent: August 29, 2017
    Assignee: SNECMA
    Inventors: Nicolas Jerome Jean Tantot, Thierry Brichler
  • Method for detecting deterioration in a turbomachine by monitoring the performance of said turbomachine
    Patent number: 9651457
    Abstract: A method for detecting degradation of a turbine engine by monitoring performance of the turbine engine, the turbine engine including plural functional modules, the method including: measuring plural physical parameters of the turbine engine to form a current performance index for the turbine engine; calculating plural degraded performance indices for the turbine engine, assuming that, for each degraded performance index, only one functional module of the turbine engine has degraded; calculating plural cost indices corresponding to the difference between the current performance index and a degraded performance index; determining an optimum cost index corresponding to the one with a lowest value for all the degraded performance indices; and detecting degradation of the module of the turbine engine, the degraded performance index of which is associated with optimum cost index.
    Type: Grant

    Assignee: SNECMA
    Inventors: Olivier Piol, Thierry Brichler, Amaury Olivier
  • Method for determining the torque and/or angular speed of a rotating shaft and a device for carrying out same
    Patent number: 9267855
    Abstract: A method allowing the reliable and accurate calculation of the torque of a shaft using two phonic wheels and a sensor, the method including correlating the signal resulting from a rotation or one sixth of a rotation with the signal resulting from the subsequent rotation or one sixth of a rotation. The length of time between two passages of teeth is calculated by interpolating the cross-correlation function using least squares interpolation.
