COMPARISON OF PROPELLER TYPE B-SERIES AND AU-OUTLINE GAWN SERIES FOR IMPROVING ON SUBMARINE PROPULSION PERFORMANCE USING CFD

Submarine propeller need some unique criteria can give bigger amount of thrust with noiseless. The submarine propeller design must able to produce the high thrust value, low pressure value, and smooth propeller streamline. This study investigates and compares some type of propeller that are B – 7 series, B – 8 series, Au – 7 Outline gawn series, and Au – 8 outline gawn series with some different parameters, that is blade diameter, number of blades, skew angle and pitch. From some models that have been compared, the best propeller is B – 8 series on 500 rpm with thrust value 25481 N, torque value 3927 Nm, average value pressure about 10608,92 Pa, and turbulance flow with average value velocity stream under 14,33 m/s
