| Abstract: | In a previous paper (Magnuson, 1977) expressions were derived for the two-dimensional surface elevation resulting from oscillatory translating pressure distributions. Wave elevations were computed for the subcritical frequency range for the uniform pressure distribution by using linearized water wave theory. This paper extends the work in Magnuson (1977) to the supercritical frequency range. Wave profiles are presented for frequencies and speeds covering the operating range of air-cushion vehicles. In addition, the power radiated into the far field is computed as a function of frequency for several speeds. |
