Abstract
Present work proposes a harmonic analysis to design a propeller with a metal composite material to analyze its displacements and natural frequencies using Ansys software. In order to evaluate the effectiveness of composite over metals, harmonic analysis is performed on both composite and metal propellers using Ansys. Proposed method shows substantial improvements in composite propeller over the metal propellers. From the results of harmonic analysis, it was found that composite propeller is safe against resonance phenomenon. In this paper effort is made to reduce frequency of the composite propeller so that advantage of weight reduction can be obtained. The comparison analysis of metallic and composite propeller has been made for the maximum displacements and the response graphs for the displacements and frequency were plotted.
