Current work intends on harmonic analysis to design a propeller of underwater vehicle with a composite material and to analyze its displacements and natural frequencies using Ansys software. Harmonic analysis is performed to evaluate the suitability of composite material for underwater vehicle propeller over NAB propeller. A propeller is a complex geometry which requires high end modelling software. The solid model of propeller is developed in CATIA V5 R17. Hexa solid mesh is generated for the model using HYPER MESH. Static analysis and Modal analysis are carried on both NAB and composite propeller in ANSYS software. The comparison analysis of metallic and composite propeller has been made and the response graphs for the displacements and frequency were plotted.

Keywords: Under Water Vehicles (UWV), Composite propeller, Harmonic Analysis, FE Analysis.

Article published in International Journal of Current  Engineering  and Technology, Vol.4,No.2 (April- 2014)
