Abstract

During the startup and shutdown process of a rocket engine high sideloads occur, due to unsymmetrical flow patterns. The deformation and its retroactive effect onto the flow within the nozzle may become severe and dimensioning limitations during a design process. A coupled simulation environment, using the DLR TAU code and the structural solver Nastran, is therefore developed and applied to the simulation of overexpanded rocket nozzles to perform a stability analysis.
