Hydrodynamic Shape Design and Self-Propulsion Analysis of a Hybrid-Driven AUG

Due to the lack of a powerful propulsion device in conventional autonomous underwater gliders (AUGs), their mobility and flexibility are insufficient, thus not being capable also ensuring stability motion route. Thus, it is necessary further develop hybrid-driven AUGs. This paper applied CFD simulation experimental analysis methods study design AUG with propeller optimized from type swept-forward swept-back wings. Through parameter adjustment, hydrodynamic configuration was optimized, optimal hull hydrofoil selection were proposed. The lift–drag ratio could be improved by up 22.5% at an angle attack 8 degrees. combined single for self-propulsion simulation. Aiming problem caused torque on AUG, strategy contra-rotating (CRP) conducted self-eliminate torque. results show that state, reduced more than 92% compared propeller, greatly reducing impact raising navigation stability.
