  • Trend monitoring of a shock absorber condition
    Patent number: 11981424
    Abstract: A method of monitoring the condition of an aircraft landing gear shock absorber, the shock absorber including at least one spring chamber containing a gas, the method comprising taking a plurality of measurements of the gas pressure and temperature, each gas pressure and temperature measurement pair being taken of at the same instant relative to an operating cycle of the shock absorber; calculating, based on each pair of gas pressure and temperature measurements, a first value; storing the first value in a log; determining a value trend based on the log; and in response to determining that the value trend is outside a first range of values, generating a first notification signal.
    Type: Grant
    Filed: November 10, 2020
    Date of Patent: May 14, 2024
    Assignees: Safran Landing Systems, Safran Landing Systems UK Ltd.

  • Aircraft landing gear and pitch trimmer assembly
    Patent number: 11155346
    Abstract: An aircraft landing gear assembly having a bogie beam pivotally coupled to a support member, and a pitch trimmer assembly including a pitch trimmer actuator configured to exert a biasing force in a first direction and a bias force transmission assembly configured to receive the biasing force in the first direction and bias the bogie beam towards a predetermined neutral position relative to the support member irrespective of the initial position of the bogie beam.
