| Summary: | Research on watercraft propulsion has been conducted since 19th century. In 20th <br />
<br />
century a lot of research and development focus on increasing efficiency and <br />
<br />
controlling cavitation. Conventional propellers have cavitation issue while the <br />
<br />
vessel achieve 30 knots (15m/s). Water-jet propulsion is a solution for vessel <br />
<br />
faster than 30 knots. <br />
<br />
Based on design requirement, calculation of pump for water-jet propulsion, design <br />
<br />
geometry, and implementation at underwater watercraft will be done. This report <br />
<br />
will reviewed about geometry, performance, and characteristic of pump. <br />
<br />
Furthermore, this report focus on the effect of non linear screw impeller to <br />
<br />
performance of water-jet propulsion and prediction of cavitaton. The performance <br />
<br />
such as thrust force, torque, shaft power, and propulsive efficiency will be <br />
<br />
observed. The result of this research is expected to help future research in design <br />
<br />
or development of high speed watercraft propulsion. |
