METHODICAL SERIES MODEL TEST RESULTS

In recent years the number of high-speed craft propelled by surface piercing propellers has increased substantially. There are now several thousand vessels operating with surface piercing propellers, including sophisticated high performance naval vessels and long distance record breakers. Surprisingly, however, very little data has been published which permits to select optimum propeller dimensions and which indicates the magnitude of propeller vertical and side forces, with their usually significant effects on craft performance. Sizing of surface piercing propellers is largely done empirically, even if a few designers have developed great expertise and accumulated an impressive know-how test, at model scale. A limited series of surface piercing propellers at model scale were tested at the high-speed free-surface cavitation tunnel of Technische Universitat Berlin, and results are discussed.
