Abstract : This report is the continuation of a research work which has already been published (AD-296 991). It refers to the determination of the camber and tickness distribution concerning a profile placed near the free surface of a flow when the pressure distribution law along the chord is given. The method allowing the utilization of the given results in the previously quoted report to obtain a profile of given hydrodynamic characteristics is presented. An analog verification of the small perturbations linear theory is given. The last part concerns the tandem problem that is studied within the scope of the same theory. An appendix shows the electrical apparatus utilized to obtain the determination of the free surface of a flow being perturbated by a distribution of singularisaties when the theoretical solution is known for one of them.
