| Abstract: | Based on the flapping wing’s two degrees of freedom motion model,numerical simulation study on hydrodynamic of flapping wing propulsion was carried out using the technology of dynamic grid computing.According to the results of simulation,the thrust and the maximum lift are approximately proportional to the swing frequency square.And the swing frequency affects the generating and fading of leading-edge eddy and tailing-edge eddy,thereby affects the thrust. |

| Keywords: | flapping-wing swing frequency dynamic grid computing eddy |
