DESIGN AND SIMULATION OF MARINE PROPELLER IN AN ADVANCE METALS ON SOLIDWORKS

Mechanical Engineering

ABSTRACT The aim of this research is to design, implement and then perform experimental comparison a MARINE PROPELLER under various metals such as Stainless Steel 304, 316, 347. Marine propellers are made from corrosion-resistant materials as they are made operational directly in seawater which is a corrosion accelerator. The materials used for making marine propeller are alloy of aluminum and stainless steel. Other popular materials used are alloys of nickel, aluminium and bronze which are 10~15 % lighter than other materials and have higher strength. The thrust from the propeller is transmitted to move the ship through a transmission system which consists of a rotational motion generated by the main engine crankshaft, intermediate shaft and its bearings, stern tube shaft and it’s bearing and finally by the propeller itself. A marine propeller is constructed by sections of helicoidal surfaces acting together to rotate through the water with a screw effect. The purpose of my project is to improve the lifetime of the product & to avoid any unavoidable incidents when running the ship. The reason why I am choosing the ides because to fulfill the factors considering for efficient ship propeller design. The factors are propeller diameter, RPM, number of blades, blade outline, angle of attack and camber, pitch/diameter ratio, stern tunnels, grouches spoilers, rudder bulb system. Here I used SOLIDWORKS software to sketch, evaluate, and some other operations in it. The operations which I have done are sketch, boss-extrude, extrude-cut, fillet, lofted-surface, metals inducing, taking results, simulation, sustainability. As I mentioned earlier, I gave the detailed report of material properties, cut-section, geometry analysis, simulation , evaluation and orthographic view. Atlast I concluded, I chosen Stainless Steel 347 is the suitable material due to its higher yield strength and maximum pressure withstand.
