Abstract
Substantial requirements for future rocket technologies are the cost-efficient access to orbit as well as the increase in the system reliability. Concerning these requirements a deeper insight into the unsteady phenomena during the start phase of modern launchers is essential. Especially unsteady side-loads, induced by the interaction of flow separation inside the nozzle, the launcher wake and the nozzle structure will play an important role for the design of future main stage propulsion systems. This so called buffeting coupling phenomenon is one of the main challenges during ascent. For the Ariane-5 configuration unsteady Detached Eddy Simulations were carried out under transonic wind tunnel conditions and validated with experimental data. For this configuration also a first coupled simulation of the flow field and the original nozzle structure of an Ariane-5 wind tunnel model is carried out to investigate resonances and loads on the nozzle.
