Critical Review on Design, Fabrication and Analysis of Marine Propeller

Sriramamurthy Bellala, Kondapalli Siva Prasad

Abstract


Ships and automated underwater vehicles like submarine and torpedoes use propeller for propulsion. The significance of propellers is to develop thrust to propel the vehicle at its operational speed. The propeller geometry and design is complicated involving many controlling parameters. Propeller with canonical isotropic materials creates more vibration and noise during their operation which is undesirable in stealth point of view. The present work is aimed at the static and dynamic analysis of aluminium-24345 material. It has high corrosive resistant, light in weight and easy to maintain. A propeller has a complex geometry and requires high end modelling in its software. The solid model of propeller blade and propeller are developed in CATIA V5 R19. Modelling and analysing the propeller blade of an underwater vehicle for their strength are carried out experimentally and analytically in the present work. By using this model, propeller will be manufactured using CNC machine. After fabrication, modal testing will be carried out to find the strength, natural frequency and damping of the propeller blade. Finite element model of the blade was modelled in ANSYS. Static, modal, harmonic analysis will be carried out on analysis software for the modelled propeller blade. Also, dynamics, CFD and acoustic analysis will be carried out on propeller with the help of ANSYS. In the present paper, review on works related to finite element analysis methods and material selection on propeller by various researchers is carried out and presented.
