- Summary:
- A model of one of the twin hulls of the Italian Savoia S-55-X flying boat (N.A.C.A. model 46) was tested in the N.A.C.A. tank according to the "general" method. The data obtained from the tests cover a broad range of speeds, loads, and tris and are given in nondimensional form to facilitate their use in applying this form of hull to any other flying boat or comparing its performance with the performance of other hulls. The results show that the resistance characteristics at best trim of this model are excellent throughout the speed range. In order to compare the performance of the S-55-X hull with that of model 35, a pointed-step hull developed at the N.A.C.A. tank, the data are used in the computations of a take-off example of a twin-hull, 23,5000-pound flying boat. The calculations show that the S-55-X hull has better take-off performance.
