Autonomous underwater vehicles (AUVs) are crucial in ocean exploration, reaching areas dangerous or inaccessible to humans. Designing these vehicles remains a challenge due to complex interactions between design parameters. This study presents an AUV designed and simulated using computational fluid dynamics to achieve lightweight construction, high maneuverability, and efficiency at depths up to 100 m. Key improvements include selecting a streamlined shell’s shape to reduce drag and enhance maneuverability and efficiency. Additionally, an efficient propeller was developed for the thrusters to lower energy consumption and extend operational time for prolonged missions. This involved designing a suitable nozzle before installing the propeller. The thrusters’ configuration and implementation were also considered for vehicle stability, maximising thrust while preventing water leakage. A comprehensive material study ensured the AUV’s ability to withstand extreme pressures at 100-m depths and resist corrosive saltwater. By focusing on these aspects, the study culminated in an efficient AUV design, furthering human understanding of uncharted ocean territories.
