Hydrodynamic characteristics of a low-drag, planing-tail flying boat hull

Henry B. Suydam

The hydrodynamic characteristics of a flying boat incorporating a low-drag, planing-tail hull were determined from model tests made in Langley tank no. 2 and compared with tests of the same flying boat incorporating a conventional type of hull. The planing-tail model had a greater range of elevator deflection and center-of-gravity location for stable take-offs than did the conventional model.
