The development and testing of propellers suitable for high-speed containerships, in particular from the cavitation point of view, is described. Optimum shape of the blade section (from the cavitation aspect), based on the calculation of pressure distributions over the chord of two-dimensional wings, is discussed. Blade sections obtained in this way were used for six-bladed propellers which were model-tested in open water and under cavitation conditions. Detailed results are presented of these systematic tests. Cavitation patterns, in uniform flow, were compared with the pressure distributions in the corresponding two-dimensional wings calculated by the lifting-surface theory. Cavitation-inception curves were obtained, and the influence of cavitation on thrust and torque was investigated. Both square root of B sub p minus delta and square root of B sub u minus delta design diagrams, from the results of the open-water tests, are presented. Cavitation tests in non-uniform flow showed that the cavitation characteristics of these "SRI.a" propellers are superior to those of MAU propellers. Order from BSRA as No. 52,648.
