Underwater mobile docking is an important development direction for recovery of an unmanned underwater vehicle(UUV),which has high requirements for integrated design and hydrodynamic design of docking stations. In order to further study the recovery technology of UUV mobile docking station,a cable towed docking station structure for surface ships is proposed,and the compact layout design and steady-state fluid performance evaluation are carried out. The attitude characteristics and docking performance of the docking station at the towed speed of 2 kn are verified through lake test using the existing UUV. The final docking success rate is up to 80%. The results show high feasibility of the proposed scheme,and have certain reference significance for the research of underwater mobile docking technology.
