  • A Novel Usage-based Prognostic for Anti-Skid and Landing Gear Systems

    Connor M. Byington†, Carl S. Byington*, Justin Zhang†, and Michael Hynson‡ Aircraft landing gear (LG) systems are subject to a wide range of stressors due to wear, fatigue, and impact driven mechanisms. Moreover, modern aircraft are often heavily reliant on avionics equipment to support anti-skid and related performance enhancements. As in many arenas, there is…

  • Joint Time Frequency Vibration Diagnostics of Main and Engine Accessory Gearboxes

    Vibration diagnostics that assume a “stationary” monitored signal are not effective for main and engine accessory gearboxes because the operating conditions (speed and/or load) of these components are often non-stationary, which leads to spectral smearing and erroneous analysis. Traditionally, this is avoided by defining steady state operating conditions in which to perform the analysis. However,…
