Abstract : A series of resistance experiments were performed at the David Taylor Naval Ship R&D Center (DTNSRDC) to determine if the trends in resistance of a group of small models having somewhat similar hull forms compare well with the trends in resistance of a group of large model geosyms. Three variants of the CVV aircraft carrier were selected for these experiments; the large models represented a scale ratio of 31.435 (8.34 m), and the small models represented a scale ratio of 144 (1.82 m). One of the small models, CVV-B, was evaluated experimentally at Davidson Laboratory of the Stevens Institute of Technology (DL/SIT) to obtain a comparison with the small model results at DTNSRDC. The results show that the small model resistance trends compare well with the large model resistance trends. The resistance of the small CVV-B model was found to be within one percent of the corresponding results from DL/SIT. (Author)
