The landing gear of the aircraft is related to smooth take-off and aircraft, most basic guarantee ensure flight safety. Therefore, maintenance particularly important, technicians must do a good job in this area. In order improve quality work, paper summarizes common faults components, analyzes main reasons for failure, puts forward relevant solutions maintenance.

Heavy aircraft main landing gear tyres skid immediately after touchdown as result of the high slip ratio between the tyres and runway, which lead to tyre wear and smoke. In this paper, the tyre wear is modelled on the Archard theory using ANSYS mechanical transient, to reveal the wheel’s dynamic and the tyre tread wear. The wheel’s dynamic and the amount of wear are calculated for initially sta...

A series of fluid dynamic and aeroacoustic wind tunnel experiments are performed at the University of Florida Aeroacoustic Flow Facility and the NASA-Langley Basic Aerodynamic Research Tunnel Facility on a high-fidelity 1⁄4-scale model of Gulfstream G550 aircraft nose gear. The primary objectives of this study are to obtain a comprehensive aeroacoustic dataset for a nose landing gear and to pro...

In this paper we consider the onset of shimmy oscillations of an aircraft nose landing gear. To this end we develop and study a mathematical model with torsional and lateral bending modes that are coupled through a wheel-mounted elastic tyre. The geometric effects of a positive rake angle are fully incorporated into the resulting five-dimensional ordinary differential equation model. A bifurcat...

Alarms have been in use for many decades, yet there still needs to be more clarity about what makes a good alarm. Vendors and government agencies developed several useful handbooks describing the Do’s Don’ts of effective alarm design; however, date, we cannot find comprehensive quantitative taxonomy or classification system that allows researchers easily score rank various designs any field—whi...
