- W640423518 abstract "A small series of tip fin propellers where the blade tip is bent towards the suction side of the blade has been designed by lifting-line and lifting-surface procedures. The propellers have been tested in the open water model basin and in the cavitation tunnel and results are compared with those of a conventional reference propeller. Open water tests showed improvements in efficiency of the tip fin propeller for thrust loading coefficients above 0.4 and for advance ratios of low and medium magnitude. At the design point an increase was found in propeller efficiency of approximately 3 percent relative to that of the conventional propeller designed for the same conditions. Comparison with the corresponding Wageningen B-series propeller shows an increase of approximately 7 percent. Propulsion tests at low to medium advance ratios and moderate thrust loading showed a power reduction of 5 to 6 percent at a rate of revolution reduced by approximately 2 percent when a tip fin propeller was applied." @default.
