“…In addition, some studies have generated laminate layups with genetic algorithms using FRP stacking arrangements in which the propeller blade is within the given parameter [ 5 , 20 ] but only within the considered solution space. Others have applied novel new ideas, such as curved fibre paths in the anisotropic shells [ 46 ], showing that there are still more possibilities for improvement in this design concept alone.…”

Four plausible design concepts are applied together to investigate composite bend–twist propeller-blade designs that show high twisting per bending deflection. The design concepts are first explained on a simplified blade structure with limited unique geometric features to determine generalized principles for applying the considered design concepts. Then, the design concepts are applied to another propeller-blade geometry to obtain a bend–twist propeller-blade design that achieves a specific pitch change under an operational loading condition with a significant periodic-load variation. The final composite propeller design shows several times more bend–twist efficiency than other published bend–twist designs and shows a desirable pitch change during the periodic-load variation when loaded with a one-way fluid–structure-interaction-derived load case. The high pitch change suggests that the design would mitigate undesirable blade effects caused by load variations on the propeller during operation.

“…The background work and procedure of the GA optimisation for a generic hydrofoil had been presented earlier by Herath et al [40,41]. Based on the past literature [42][43][44] and the previous work on hydrofoil [45,46], a real-coded GA combined with an elitist strategy was applied for better efficiency and faster convergence. Two elites were passed to the next generation, and half the number of the remaining sequences were produced using crossover and the other half by mutation until the final convergence is reached in GA.…”

Fibre reinforced composites materials offer a pathway to produce passive shape adaptive smart marine propellers, which have improved performance characteristics over traditional metallic alloys. Automated fibre placement (AFP) technology can provide a leap forward in cyber-physical automated manufacturing, which is essential for the implementation and operation of smart factories in the marine propeller industry towards Industry 4.0 readiness. In this paper, a comprehensive structural health monitoring routine was performed on an AFP full-scale composite hydrofoil to gain confidence in its dynamic and structural performances through a number of active and passive sensors. The hydrofoil was subjected to constant amplitude flexural fatigue loading in a purpose-built test rig for 105 cycles. The hydrofoil was embedded with distributed optical fibre sensors, traditional electrical strain gauges and linear variable displacement transducers. Both microelectromechanical system and piezoelectric accelerometers were used to conduct experimental modal analyses to observe changes in the modal response of the hydrofoil at regular intervals throughout the fatigue program. The hydrofoils modal response, as well as the stiffness measured using both displacements and strains, remained unchanged over the fatigue loading regime demonstrating the structural integrity of the hydrofoil. The optical fibre sensors endured the fatigue test cycles showing their robustness under fatigue loads. Furthermore, the sensing systems demonstrated the potential of being utilised as a useful maintenance tool combining their adaptability with automated manufacturing during manufacturing through integration within the hydrofoil, a structural test framework for performance measurement, data acquisition and analytics for visualisation, and the prospect of decision making for maintenance requirement during any onset in structural performance.

“…Cavitation is the phenomenon of gas bubbles forming on the propeller blades due to pressure reduction, which can cause erosion, efficiency loss, noise, and vibration to the marine propeller. Composite materials have gained widespread usage in enhancing the hydrodynamic performance of propellers because of their exceptional mechanical characteristics [1][2][3]. Previous research on hydrodynamic response in composite hydrofoils under cavitation conditions has provided valuable insights that serve as the foundation for investigating cavitation in composite propellers [4][5].…”

The hydrodynamic performance of a composite propeller under cavitation conditions is analyzed considering the bidirectional transient fluid-structure coupling. The structure field and the flow field are calculated using ANSYS Mechanical/CFX and the information is transferred between them by the interface. It indicates the unsteady cavitating flow features in the presence of the wake condition manifest periodic tendencies. Additionally, the hydrodynamic coefficients of the composite propeller display a phase delay. The composite propeller demonstrates decreased volume of cavitation and enhanced efficiency. The bend-twist coupled deformation in the propeller mitigates the effects of cavitation loads on the performance.
