Design and hydrodynamic coefficient identification of deep-sea unmanned underwater vehicles
Year: 2025
Type: conference-paper
Abstract: This study initially designed a deep-sea unmanned underwater vehicle (UUV) employing a double-hull pressure-resistant structure, resolving pressure containment challenges through a three-tier protective system comprising “pressure-bearing inner hull, oil-filled buffer layer, and flow-guiding outer shell.” Subsequently, computational fluid dynamics (CFD) methodology was employed to conduct flow field analysis and numerical simulations of the vehicle. Ultimately, the acquisition of key hydrodynamic coefficients for the UUV was achieved through multiple linear regression methodology. This research establishes theoretical foundations for deep-sea UUV design, with particular emphasis on the derivation of critical hydrodynamic coefficients, providing essential support for subsequent motion control modeling of autonomous underwater vehicles (AUVs).
