A non linear method is presented for calculating potential flow around lifting bodies. Ther perturbation potential is taken as unknown at the surface, while its value is fixed inside the body. This method is particularly well suited to cases of thin structures; It is applied to calculate the flow around a non-cavitating marine propeller for which several difficulties are examined and solutions proposed : problem of the JOUkOwki condition. problem of propeller mesh, wake description. The influence of the hub and the calculated wake on numerical results are analysed.
