N2 - Systematic flow measurements were performed around a typical propeller strut of 13.8% in thickness ratio, designed for a high speed-boat engine, in a low turbulence wind tunnel as well as a cavitation tunnel, and also around a real strut equipted for an engine at sea. A relatively small drag coefficient CD ≠ 0.02 was obtained in the wind tunnel, indicating a strut having reasonable hydrodynamic performance. We also discussed the state of the boundary layer, the thickness distribution, the velocity distribution, the behavior of the following wake and cavitation performance.
