Loxodromic towing test at low speed and large drift angle for deep sea open-framed remotely operated vehicle

This paper presents the newly designed loxodromic towing test on the horizontal plane for the scaled model of 4500m deep sea open-framed remotely operated vehicle (ROV), which is being researched and developed by Shanghai Jiao Tong University. Accurate hydrodynamics coefficients measurement is significant for the maneuverability and control system design. The scaled model of ROV was constructed by 1:1.6. Hydrodynamics tests of large drift angle were conducted through LAHPMM under low speed. Multiple regression method is adopted to address the testing data and obtain the relating hydrodynamic coefficients. The data obtained is the base for the application and operation of ROV in the practical missions.
