Static and Fluid Analysis of a Marine Propeller

Santosh Kumar, Gill / Mahesh, Boddapalli

Ships and underwater vehicles like submarines and torpedoes use propellers for propulsion. These propellers consist of various blades and have also been constructed using different materials as time has passed. This project aimed to model ship propellers based on a standard four-blade INSEAN E779a model and vary it concerning materials and number of blades. Here, the procedure used to model and analyze the propeller blades has also been discussed. SIEMENS NX 11.0 was the software used to model the propellers, while ANSYS 19.2 was used to perform Static Structural and Computational Fluid Dynamic Analyses of these propellers. The analyses were carried out for two materials, namely, Aluminum and Carbon: fiber Reinforced Plastic, for rake angle 4.05°. The results obtained from the CFD and Static Structural analyses helped determine which propeller performed the best when compared across different parameters like the velocity of water around the propeller, the pressure developed by the propeller, stresses, deformations, and strains developed within the propeller when subjected to a thrust. The modifications made to the propeller in terms of material, number of blades suggested which variant of the propeller is best suited for different requirements of the Ship. For higher speeds, the three-bladed propellers proved to be more effective, while the four-bladed propellers were seen to experience lesser stress and deformations due to the thrust. The current study examines the structural properties of a CFRP (carbon fiber reinforced plastic) propeller blade that is being considered as a replacement for aluminum propeller blades. Depending on the operating depth, the propeller is subjected to external hydrostatic pressure on both sides of the edges, and flows around the propeller were computed.
