Flight dynamics of composite bodies can't often be successfully modelled by means of six degrees of freedom model. Additional degrees of freedom have to be introduced, involving mechanical and aerodynamic interactions between both bodies. The number of additional degrees of freedom in the model presented in this paper can be parameterized to take into account various link conditions. A "theoretical" validation is first presented in a 9-dof payload/parachute mode. A complementary validation based on a ribbon stabilized grenade experimentally tested in a vertical wind tunnel show a good predictive capability of the model.
