Tandem propellers, defined as two propellers coaxially mounted to the same shaft, were characterized in open water. The motivation for this work was to determine if the reduced loading per propeller would improve efficiency. Other potential gains such as reduced vibration and decreased cavitation are to be studied later. The experiments were performed at two angular positions and only one axial spacing for direct comparison to a standard parent propeller. The performance shows that improved efficiency is obtainable with tandem propellers. The results also show that changes in performance occur with different angular positions of the propellers. Additional experiments are recommended. (Author)
