| description | This study investigates the hydrodynamic characteristics and optimal profile of a novel unmanned underwater platform, the Twin Hybrid Autonomous Underwater Vehicle (THAUV). The THAUV comprises two torpedo-shaped buoyancy bodies and a fixed-wing. Its propulsion system consists of two buoyancy engines and two thrusters. Compared to conventional hybrid autonomous underwater vehicles (HAUVs), the THAUV offers increased carrying capacity for instrumentation and energy, allowing for extended operational durations. Computational fluid dynamics (CFD) simulations were conducted to analyze the hydrodynamics of each component. The study also investigated the linear change in lift force and quadratic change in drag force in response to variations in angle of attack, along with analyzing drag, hydrodynamic forces, and moments acting on the vehicle's hull over time. At the mechanism velocity, a 12° increase in the angle of attack leads to a 150 % rise in drag force and an additional 80 N in lift force. Furthermore, the drag force oscillates approximately 58.4 N over 10 s. The findings demonstrate the suitability of the THAUV structure for further research, as evidenced by the alignment between numerical results and experimental observations. |
