A Compendium of Resistance, Sinkage and Trim, and Longitudinal Wave Cut Measurements Obtained on Model 5365

Abstract : Model 5365 is a 1/8.25th scale representation of the R/V Athena. This report documents both a new set of resistance, sinkage and trim, and longitudinal wave cut experiments as well as historical calm water resistance and sinkage and trim data which have been obtained on this model over the past few decades. The new resistance data were obtained in October and November of 2006 on Carriage 2 at the Naval Surface Warfare Center, Carderock, Division. In these experiments drag force was measured using both 6-component Kistler gages and a traditional block gage at the tow post location, as well as a Kistler gage located at the grasshopper bracket model attachment point. An in-situ calibration was also performed in order to verify loads at the tow post and grasshopper bracket location when a known load was applied to the system. Video and still digital cameras were also used to qualitatively characterize the wave field during the runs.
