Recently, the composite propeller has attracted attention. In general, it is well known that the composite propeller is expected to reduce cavitation by deforming in conformity with unsteady flow field variation behind the hull. However, the design method applying such advantages effectively has not been established. Therefore, the authors have been studying how to predict the performance of composite propellers by using Fluid Structure Interaction (FSI) analysis. At the same time, the measuring system by using Combination line CCD camera method has been developed by NMRI. There are several studies on the deformation measurement of composite model propellers, but there is little study about the comparison between FSI analysis results so far. In this paper, we carried out comparisons of the experimental results and FSI analysis. It was confirmed that the calculated results regarding hydrodynamic characteristics and deformation of the propeller blade agree well with experimental results.
