Comprehensive design of an oleo-pneumatic nose landing gear strut

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2020
A comprehensive design cycle of a nose landing gear strut having an oleo-pneumatic shock absorber for a lightweight aircraft is proposed. Design and analysis of a retractable nose landing gear according to Airworthiness Standards FAA FAR Part 23 have been carried out. This research is focused on mathematical modeling of an oleo-pneumatic strut with an

Influence of Tire Inflation Pressure on Nose Landing Gear Shimmy

Journal of Aircraft, 2010
This work investigates shimmy oscillations in the nose landing gear of a passenger aircraft and studies how they depend on changes in the tire inflation pressure. To achieve this, a mathematical model of a landing gear is considered that includes the influence of the tire pressure via different tire properties, such as cornering force and contact patch

Hopf Bifurcation Analysis of a Nose Landing Gear System of Aircraft

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering
The Hopf bifurcation problem of a nose landing gear system is investigated. Taking the nearly smooth landing gear system with high-order nonlinear terms as the research object, the nose landing gear system is simplified to a plane dynamic system ...

Aircraft Landing Impact Parametric Study with Emphasis on Nose Gear Landing Conditions

Journal of Aircraft, 2002
A parametric approach to simulation of landing impact, with pitching and heaving degrees of freedom of the aircraft motion, has been used to determine the response of the main and nose gears. Compared to each gear's independent behavior, there are important differences in the landing conditions and in the resulting vertical loads and displacements when

Effect of Torsional Damping on Aircraft Nose Landing-Gear Shimmy

Journal of Aircraft, 2015
The bifurcation analysis method is applied in dealing with shimmy oscillations of the aircraft nose landing gear. Algorithms and details of the procedure in bifurcation analysis are described. Torsional damping of the antiswing damper is studied based on the model consisting of torsional and lateral bending modes of the landing gear.

Aeroacoustic Study of a Generic Nose Landing Gear Focusing on the Torque Link

Journal of Aircraft
Far-field aeroacoustic measurements were conducted on a 30%-scale generic nose landing gear model, using a phased microphone array. Nine model configurations were tested, created from different combinations of strut, wheels (with or without cavities ...
