Static and Rrotordynamic Analysis of Composite Blade Marine Propeller

Abstract

This project work deals with modelling and analysing the propeller blade of a marine vehicle for their strength. A propeller is a complex geometry which requires high end modelling software. The solid model of propeller is developed by using Solidwork 2014 & Matlab R12.The meshing is generated for the model using Ansys. Static and rotordynamic analysis of composite blade propeller is carried out in ANSYS 14.5 software. The stresses obtained are well within the limit of anisotropic property of the materials. The deflection for composite blade propeller is determined. Optimal solution was found by using TAGUCHI method. The critical speed of the propeller is determined using rotordynamic. On comparison which shows that by changing different parameters like speed of shaft and pressure of water on propeller we found optimum solution for the design of propeller.
