Based entirely on momentum and other simple considerations, reasonably complete picture of one-dimensional pressure and velocity fields associated with heavily supercavitating propellers and drag disks has been constructed; it is shown that flow is often retarded while approaching heavily supercavitating propeller, so that so-called ideal efficiency of such propeller takes on values in excess of unity, and this aspect is clarified; retardation causes reduction of thrust deduction, or even change in its sign; charts are provided from which inflow speed may be estimated; effect of water-tunnel boundaries is discussed.
