Unsteady numerical simulation about the mutual effect between the nacelle and the propeller's slipstream was carried out based on unstructured overset grids algorithm. In order to better capture the detail of the propeller vortex structure, improved delayed detached eddy simulation (IDDES) based on Spalart-Allmaras model was employed, and the adaptive grid technique was used to improve the spatial resolution of the flow field's characteristics during the unsteady process. Research results show that the thrust coefficient calculated by IDDES agrees well with the experimental data, and the existence of the nacelle increases the thrust coefficient of the propeller. The nacelle has a great influence on the structure of the hub vortex but little effect on the structure of the propeller tip vortex. For the propeller without nacelle, both the instability process of the tip vortex and the hub vortex show obvious periodic characteristic. The inception region and the paring effects of the tip vortex of the propeller without nacelle are the same as those of the propeller with nacelle, which indicates that the hub vortex has no effect on the instability of the tip vortex.
