Hydrodynamic Tests in the N.A.C.A. Tank of a Model of the Hull of the Short Calcutta Flying Boat
This is a 1937 NACA technical note reporting hydrodynamic tank tests on a scale model of the hull of the Short Calcutta flying boat, issued by the National Advisory Committee for Aeronautics for aircraft engineers and researchers. The pages are dense engineering line charts plotting resistance and trimming-moment coefficients against speed coefficient, with curves labelled by load coefficient and trim angle on gridded paper, offering a designer little beyond the clean grid layout and the stepped, labelled curve families.
