ADDED MASS AND DAMPING OF THE HEAVING SURFACE EFFECT SHIP IN UNIFORM TRANSLATION

The analysis presents a practical method for evaluating the added mass and damping coefficients of a heaving surface effect ship in uniform translation. The theoretical added mass and damping coefficients and the heave response show fair agreement with the corresponding experimental values. Comparisons of the coupled aero-hydrodynamic and uncoupled analytical results with the experimental data prove that the uncoupled theory, dominant for a long time, that neglects the free surface effects is an over simplified procedure. The analysis also provides means of estimating the wave elevation of the free surface, escape area at the stern and the volume which are induced by a heaving surface-effect ship in uniform translation in otherwise calm water. Computational procedures have been programmed in FORTRAN IV language and adapted to the PDP-10 high-speed digital computer. (Author)
