Starting from known values of total thrust, number of revolutions, propeller diameter, blade number and form, distribution of blade circulation, duct vorticity, minimum cavitation margin, etc, method determines propeller efficiency, blade area, duct thrust, shape of duct and pitch, number and thickness of propeller blade sections; for verification, tests in homogeneous flow with four different heavily loaded propellers were carried out in cavitation tunnel; measurements of thrust and torque, determination of incipient cavitation and flow visualization studies are described.
