Abstract

Marine ducted propellers are rotating duct fan that are used on tugs and trawlers which creates a greater propulsive thrust force to drive over a water medium on heavy working condition in harbour. This paper progresses with comprehensive information of marine ducted propeller. Which blade made of aluminum alloy and duct of alloy steel is designed and analyzed with various blade formations 4 and 5 separately and to check the performances of each blade individually to show which blade performs efficiently better with maximum velocity rate under stream line motion on water at dynamic condition. Ducted propeller is modeled in solid works. Hydrostatic and hydrodynamic analyses of each blade are performed with ANSYS workbench.
