Shock Absorber Leakage Impact on Aircraft Lateral Stability During Ground Handling Maneuvers

Aircraft braking maneuvers are safety-critical on-ground motions that exhibit complex dynamics and significant dependence on system operating conditions. The fundamental interface between the aircraft ground is landing gear. Among gear components, shock absorbers may be subject to gas leakage during their lifetime, which an anomaly could compromise lateral stability properties of regimes found maneuvers. In this paper, explicit link established main absorber stability. To investigate stability, a high-fidelity multibody nonlinear simulator developed in MATLAB/Simulink framework validated against experimental data. generate insight into problem quantify impact two simple but descriptive analytical models also developed, each one different mode system. analysis reveals can have effect especially at high velocities highly damped nose wheel steering work used by control designers come up with more effective controllers event leakage.
