Dynamic Response Analysis of Generic Nose Landing Gear as Two DOF System
Landing gear is a structural component of an aircraft to support the weight while it is on the ground and also to aid safe landing. A generic analytic model for linear dynamic analysis of landing gears, which captures responses of individual components, is seldom available in literature. In the present work an analytical model for the linear response analysis of landing gear is developed. The l...
متن کاملInteraction of torsion and lateral bending in aircraft nose landing gear shimmy
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...
متن کاملAircraft Landing Gear Design & Development
Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...
متن کاملThe Landing Gear Case Study in Hybrid Event-B
A case study problem based on a set of aircraft landing gear is examined in Hybrid Event-B (an extension of Event-B that includes provision for continuously varying behaviour as well as the usual discrete changes of state). Although tool support for Hybrid Event-B is currently lacking, the complexity of the case study provides a valuable challenge for the expressivity and modelling capabilities...
متن کاملAeroacoustic Analysis of a Simplified Landing Gear
A hybrid approach is used to investigate the noise generated by a simplified landing gear without small scale parts such as hydraulic lines and fasteners. The Ffowcs Williams and Hawkings equation is used to predict the noise at far-field observer locations from flow data provided by an unsteady computational fluid dynamics calculation. A simulation with 13 million grid points has been complete...
