V-shaped wing design and hydrodynamic analysis based on moving base for recovery AUV

Aming at AUV capture and recovery, a moving base–V-shaped wing that can increase the recovery success rate of AUVs is designed in this paper. The Bernoulli equation of the ideal fluid is used as the design principle. The SolidWorks is used to design the V-shaped wing in three dimensions. The CFD simulation software is used to simulate the hydrodynamics of the V-shaped wing. Calculation results show that the V-shaped wing can generated down force and the resistance increases with the increase of speed. The V-shaped wing is 3D printed and the water test is conducted. When the towing speed is 2 knots, the V-shaped wing can generate 11N down force and can keep stability of the depth.
