| Abstract: | Three-dimensional unsteady incompressible N-S equation is solved by numerical method and the corresponding three-dimensional dynamic mesh is generated. The flapping motion and unsteady flowfield of flapping-wing MAV in different frequencies,different angles of attack,different velocities,different amplitudes and different initialized positions of wing are simulated.The lift and drag coefficient of flapping-wing MAV in different motion modes are calculated.The factors that influence the characteristic of aerodynamics of flapping-wing MAV are analyzed,which provided the academic warrant for the flying mechanisms and fabrication of flapping-wing MAV. |

| Keywords: | numerical simulation flapping-wing MAV dynamic mesh low Reynolds number |
