Destuynder, P. (author), Santi, F. (author)An aeroelastic modelling of an axisymmetrical airship is discussed in this paper. The main difficulty is due to the fact that instabilities are not axisymmetrical. Furthermore an Euler-Lagrange kinematical coupling is necessary in order to represent the fluid-structure interaction. Our strategy is based on some arbitrary change of domain (for...conference paper 2006
