Cavitation performance of four variable pitch propellers is evaluated and presented for comparison with PROTEUS Propulsion Research and Open-Water Testing of Experimental Underwater Systems open-water test results. All four variable pitch propeller models are members of a parametric series with common characteristics. Cavitation performance of the Newton-Radar propeller 4447 with the ventilation ring attached to the model pod are also presented. Results of open-water characteristics of the Newton-Radar propeller are compared with the test results of June 1971. Curves of the cavitation performance of two of the propellers under various conditions of ventilation are also presented.
