Original Paper


The paper presents numerical models and simulations performed at ONERA to investigate aerodynamic effects on the trajectory of an open rotor blade fragment released or lost during an engine burst event. The models are based on finite elements for the structural part and on finite volumes for the fluid part, and are implemented in the EUROPLEXUS explicit code. Fluid–structure interaction is taken into account by an embedded (or immersed) technique and precision is enhanced by refining the fluid grid locally using automatic mesh adaptivity. A new methodology has also been implemented to limit the air volume to be discretized in the numerical model, thus reducing the size of the fluid mesh and allowing fine-mesh (adaptive) computer simulations in a reasonable CPU time.
