Cavitation and Ventilation Experiments of Four Controllable Pitch Propellers for the Open Water Research Vehicle,Proteus.

摘要

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.
