The first report defined the general principles of utilization and construction of a analog tank for studying the perturbation potential around lifting surfaces submitted to an helicoidal movement. The prese t report, which utilizes the sa e quotations, gives the results obtained with this tank in the resolution of various elementary problems. These determinations were used for the final setup of the analog model which can be considered as correspondingACCURATELY TO ITS ANTICIPATE FUNCTIO . (Author)
