Riassunto
The present work has been carried out during a 12 months Internship in the Landing Gear Centre of Competence, Design Analysis Team (ELYD) within Airbus Operations Ltd at Filton, UK.
One of the main activities of ELYD is to provide results to Program ATA32 Integrators and Chief Engineers (ATA Chapter numbers provide a common referencing for all commercial aircraft documentation and ATA32 is the chapter regarding the Landing Gear) concerning aircraft performances during ground operations.
Currently rigid Landing Gear models are used to simulate dynamic ground manoeuvres using the software MSC ADAMS/View.
The aim of this thesis is to investigate how flexibility in Landing Gear can affect aircraft performances on ground operations.
Two different ways of representing flexibility have been considered during this work: Beam model and mnf model.
The comparison against the beam model has been done on the A350XWB. The comparison against the mnf model has been done on A320. This is due to model availability within Airbus.
Simulations show little differences in terms of turning performances. Flexible models give a more accurate load transfer to the airframe, however they require a much higher simulation time.
