Abstract: Carbon fibre composite has exceptionally high strength, low density and corrosion resistance in the marine
environment compared to conventional materials. These characteristics make it a favourable alternative material to be
considered for manufacturing marine screw propellers. Despite these advantages, the flexibility of the material leads
to a significant change in blade geometry due to loads acting on blades which alter hydrodynamic performance. A twoway coupled fluid-structure interaction analysis is required to accurately capture its hydrodynamic performance due
to the reduced stiffness and material anisotropy. The present study focuses on numerical investigation for the hydroelastic based performance analysis of a composite marine propeller in open water condition. The procedure involves
the coupling of Reynolds-Averaged Navier-Stokes Equation based computational fluid dynamics solver with the finite
element method solver using co-simulation technique. The open water characteristics, including thrust coefficient,
torque coefficient and open water efficiency, are discussed as a function of advance ratio. This paper presents a
comparison of the hydrodynamic performance and structural responses between a carbon fibre composite propeller
and a conventional steel propeller which are geometrically identical. The results for the composite propeller show a
significant improvement in hydrodynamic performance compared to the metallic propeller while remaining structurally
safe throughout the tested range. © 2021: The Royal Institution of Naval Architects.
