内容記述 | In order to clarify the fundamental mechanism of the hovering flight of a dragonfly, the numerical simulation of unsteady viscous flow around a tandem airfoil configuration oscillating in still air has been conducted by using a two-dimensional Navier-Stokes code. It is shown that the mutual flow interactions between the fore-and hind- airfoils are playing the dominant role in generating the time mean aerodynamic force acting in the direction of the stoke-plane, which is indispensable for the dragonfly to hover with the body axis horizontal. Total amounts of the lifting force and the necessary power are also estimated and shown to be very close to those estimated by other researchers. In order to validate this numerical simulation, the experimental flow visualization around the tandem airfoil configuration has been performed in the water by using the electrolytic precipitation method. It has been shown that the flow patterns obtained are very close to those predicted by the numerical simulation. The total time mean aerodynamic force predicted by the numerical simulation has also been evaluated by using a dragonfly robot machine which can hover in the water, validating that the numerical prediction of the total lifting force is within the error of about 12 percent. | |||||
