Abstract

Model tests for a stern flap have been performed to decrease the resistance of a large warship and to optimize the flap. Stern flaps and wedges of fast crafts are studied to apply to a large vessel in terms of speed-length ratio. The model tests of the flap has been carried out to find the effects of the design parameters, i.e. length and angie on resistance decrease. This work concludes that the optimized stern flap reduced resistance not only at the high speed by 9％ but also at the cruising speed.
