The present work deals first with some experimental work and their modelling by various F.E. methods. A confrontation of the different numerical approaches is done (lagrangian, ALE and SPH) in the field of fluid/structure interactions. In the second part, the document describes crash and ditching simulations of a complete commercial aircraft model which is being built up by ONERA and AIRBUS France.
