This work formed part of a comprehensive study of the hydrodynamic behavior of remotely operated underwater vehicles undertaken by the National Maritime Institute. The aim was to provide reference performance data on a remotely operated vehicle (ROV) and to represent the dynamics of such craft by a mathematical model obtained using the results of experiments on actual craft. Experiments were carried out on a small vehicle of the flying eyeball type and were designed to measure total thrust generated by the propeller/duct combination and transmitted to the craft, and the torque required at the propeller to produce the measured thrust. Results were obtained over a range of propeller blade pitch angles and for positive and negative advance coefficients. The performance of the thruster was compared with that of other marine screw propellers and the effect on performance of seaweed guards at duct entry and exit was evaluated.
