Bifurcation Analysis of a Coupled Nose-Landing-Gear–Fuselage System [PDF]
Journal of Aircraft, 2014 Under certain conditions during takeoff and landing, pilots may sometimes experience vibrations in the cockpit. Because the cockpit is located right above the nose landing gear, which is known to potentially be prone to self-excited vibrations at certain velocities, an explanation for those vibrations might be oscillations of the landing gear feeding ...

Simulation of Nose Landing Gear Shimmy with Flexible Airframe Considered [PDF]
Xibei Gongye Daxue Xuebao, 2018 Shimmy stability of the nose landing gear of an aircraft is studied in this paper. Firstly, Shimmy model was built considering the dynamic characteristics of the airframe. Then the critical damping, critical velocity and frequency range of the shimmy are

Bifurcation Analysis of Nose-Landing-Gear Shimmy with Lateral and Longitudinal Bending [PDF]
Journal of Aircraft, 2010 This work develops and studies a model of an aircraft nose landing gear with torsional, lateral, and longitudinal degrees of freedom. The corresponding three modes are coupled in a nonlinear fashion via the geometry of the landing gear in the presence of a nonzero rake angle, as well as via the nonlinear tire forces.

Bifurcation Analysis of a Nose Landing Gear System [PDF]
15th Dynamics Specialists Conference, 2016 A methodology is proposed to enable the bifurcation analysis of a multi-body nose landing gear (NLG) model by coupling AUTO, a continuation software, to LMS Virtual.Lab Motion, a multi-body software. The approach uses a Singular Value Decomposition (or High Order Singular Value Decomposition) based technique to enable the computation of the stability ...

Dynamic Testing and Fatigue Analysis of the I-31P Nose Landing Gear
Fatigue of Aircraft Structures, 2023 The landing gear is a critical safety component of any aircraft, playing a key role in managing the significant loads experienced during landing and ground maneuvers. In the case of the I-31P aircraft, a redesign of the I-23 landing gear system, required

Safety Listening in High-Risk Situations: A Qualitative Analysis of Responses to Safety Voice in Aviation. [PDF]
Risk AnalABSTRACT Safety listening—responses to voice acts aimed at preventing harm—can avert organizational failures like airplane crashes. Research often focuses on attitudes and perceptions of listening using self‐report measures; consequently, little is known about how safety listening occurs behaviorally and influences safety outcomes in high‐risk ...

Design and Analysis Aircraft Nose and Nose Landing Gear [PDF]
Journal of Aeronautics & Aerospace Engineering, 2015 Tri-cycle arrangement landing gear is extensively used as it is simple; convenient both structurally as well as aerodynamically. Though it is advantageous over other configuration is has its own draw backs. Factors like its weight drag, sudden application of load, acoustics, fatigue etc tend to slow down its performance and life.
