Force Generation Mechanism of a Wing Model in Drosophila Voluntary Take-Off
Take-off is an essential stage of all flight. In the present paper, the aerodynamic performance and force generation mechanism in drosophila voluntary take-off have been studied numerically. The approach involves the simulation of the flow by solving the two-dimensional unsteady incompressible N-S equations. The wing motion model is established based on the results of experiment. Insights into the unsteady aerodynamic force generation process are gained from the force and flow structure information. The results show that the second flap is the main propulsive phase. Both added inertial forces and vorticity induced forces are important to the force generation.
