Finite element analysis of marine propeller with CFRP and GFRP

Propellers are an important part of the power transmission system in maritime engineering. They are attached to a shaft that extends from a ship’s or marine vessel’s engine. A propeller is a fan-shaped structure that has a significant impact on a ship’s propulsive performance, making it an important energy-saving component. Rotational motion is converted into thrust power by the propeller or propulsive fan. Water is propelled through the ship’s blades, dividing the force into two vectors: one pushes the vessel axially, while the other generates the necessary torque. Most large ferries and ships employ twin screw propellers to maximize torque and push the vessel forward or backward. The propeller’s material also plays an important role in achieving maximum efficiency and component life. The structural integrity of a propeller as well as temperature distribution for various composite materials such as carbon fiber reinforced plastic (CFRP) and glass fiber reinforced plastic (GFRP) are the subjects of this research (GFRP). SolidWorks 2020 was used to design a B-type twin screw propeller, while ANSYS 2021 R1 was used to conduct structural and heat flux analysis. According to the investigation, CFRP has less induced stress, low deformation, and high heat dissipation than GFRP.
