The theory of the dynamics of peripheral jet ACV is presented. The flow patterns under the bottom of ACV are classified into two types, i.e. underfed and overfed regimes. The mathematical models associated with such regimes are presented and the equations of those models are derived. The forced heaving oscillation of two-dimellsional ACV model is investigated experimentally-Variations of cushion pressure and lift force are measured and compared with the results obtained by the numerical calculation. The coincidence of these two results seems to be reasonable. The heavillg motion of ACV which is induced by the simple harmonic oscillation of the ground board is also analyzed numerically.
