This study delves into the hydrodynamic characteristics of a distinctive unmanned underwater platform, the two single-body autonomous underwater vehicle (TSB AUV). Comprising two torpedo-shaped buoyancy bodies and a fixed wing, the TSB AUV boasts a propulsion system equipped with two buoyancy engines and two thrusters. This arrangement facilitates vertical and horizontal movement, making it well-suited for missions at the seabed. By employing computational fluid dynamics (CFD) simulations, we investigate the hydrodynamics of each component of the TSB AUV, considering the influence of fluid flow on its profile to enhance hydrodynamic efficiency. The findings of this study confirm the suitability of the TSB AUV structure for further research, as evidenced by the alignment between numerical results and experimental data.

摘要

This study delves into the hydrodynamic characteristics of a distinctive unmanned underwater platform, the two single-body autonomous underwater vehicle (TSB AUV). Comprising two torpedo-shaped buoyancy bodies and a fixed wing, the TSB AUV boasts a propulsion system equipped with two buoyancy engines and two thrusters. This arrangement facilitates vertical and horizontal movement, making it well-suited for missions at the seabed. By employing computational fluid dynamics (CFD) simulations, we investigate the hydrodynamics of each component of the TSB AUV, considering the influence of fluid flow on its profile to enhance hydrodynamic efficiency. The findings of this study confirm the suitability of the TSB AUV structure for further research, as evidenced by the alignment between numerical results and experimental data.
