Abstract:

Composite materials have high strength-to-weight ratios, improved material damping properties, and their fiber orientations can be exploited to tailor the structural deformation. Composites for marine propellers can be used to reduce fluttering and to improve the hydrodynamic efficiency. Researches at home and abroad on composite marine propellers are reviewed and summarized, which reveals that the conventional calculation algorithm of metal propellers is not suitable for the design and prediction of composite marine propellers. The design and calculation of composite marine propellers need the consideration of the wake flow change resulting from the deformation of propeller blades. The mechanism is analyzed with the help of the bending-twisting coupling characteristics of anisotropic composites. In these composites the fibers can be aligned and stacked and a high efficiency propeller can, with suitable blade configuration, thus be achieved. During the study of composite marine propellers, critical factors are identified. Finally the flowchart of design of composite marine propellers is suggested, and further research topics on composite marine propellers are proposed.
