Added Resistance and Power of a Frigate in Regular Waves

摘要

Added resistance and powering in waves characteristics of the FFG-7 class frigate are presented. Added resistance results for a towed model are presented for two Froude numbers and a range of wavelengths and headings. Experimentally measured added resistance was found to be in reasonable agreement with theoretical predictions in head and bow seas, while measurements at other headings did not show satisfactory correlation. Experiments were also performed with the model powered at the ship self propulsion point for one speed and two headings, and it was found that self propulsion did not have a strong effect on the measured added resistance.
