Abstract

The present paper illustrates the potentialities of a Rankine source panel method to the hydrodynamic analysis of advanced vehicles. The framework of the mathematical model was the linear steady Rankine source formula- tion for the mono hulls wave resistance characterisation presented in ref 1. The theoretical formulation of the linearized boundary value problem for the steady wave perturbation which takes into account also the perturbation due to an air supported catamaran (SES) is provided. Extension of the monohull methodology has been carried out to account for twin hull configurations and air cushion catamarans. The former problem was more troublesome from a computational point of view as it involved a redefinition of the free surface grid and of the finite
