| Research Abstract |
The theory of animals' flying and swimming based on the Navier-Stokes equations in two-dimensional space was extended to the three-dimensional case. The procedure to construct the two-dimensional theory was applied to the three-dimensional case. It was shown that the paradox of hovering insect in two-dimensional space is resolved in the three-dimensional case. The stability of the hovering was analyzed for some cases. For the propulsion at low Reynolds numbers, a hydrodynamic model which imitates protein machine was developed. This model has been analyzed in terms of controlling period, increment in a period, and energy efficiency.
