Abstract [en]

The present paper describes the development of a finite element based tool at the launcher directorate of the French Space Agency (CNES) in order to support the ground study and testing of fairing separation systems.The main topic is the finite element modeling process and its validation. The considered finite element methodsand resolution algorithms are presented, with a focus on shell element formulations in the used finite element packages. The model results are compared with those obtained for a separation system with a pre-existing modeland a ground test. The developed model shows good agreement with the reference results and enables the CNESto fulfill its technical support role.
