• Time asymmetric flapping

Based on the analysis of the bumblebees flight, the kinematic model of time asymmetric flapping hovering wing was established, and the effect of different time asymmetric flapping on the aerodynamic performance of the wing was numerically studied by solving three-dimensional laminar Navier-Stokes (N-S) equation. The results show that the wing with appropriate time asymmetric flapping possesses enhancement aerodynamic performance. Through the analysis of flow field of different time asymmetric flapping wings, it was also found that the enhancement rotational circulation, stronger leading edge vortex and spanwise flow were observed for the wing with appropriate time asymmetric flapping, hence leading to enhancement aerodynamic performance.
