Abstract
In turbofan engine, ice accretion on the fan blade may block the flow path and disturbs the inlet flow, which will cause the decrease of the thrust and the increase of the vibration amplitude of the engine. More seriously, ice shedding can damage the compressor components, which may cause serious aircraft accidents. An understanding of the mechanisms responsible for ice shedding process is necessary in order to optimize the fan blade design to avoid hazardous ice shedding. In this paper, a numerical ice shedding model is developed by taking the coupling of the failure of the interface between ice and fan blade surface and the failure of ice itself into account. The ice shedding process is predicted and analyzed. Some factors that affect the break-up and shedding of the ice are discussed, which include the mechanical properties of the ice, centrifugal loading and vibration loading. This model could be used to further study on the ice debris trajectory prediction and ice impact analysis.
