The Application of Planing Characteristics to the Calculation of the Water-Landing Loads and Motions of Seaplanes of Arbitrary Constant Cross Section

Abstract

The general equations governing the fixed-trim water landing of a straight-keel seaplane with a hull of arbitrary constant cross section are presented in such a form that the landing motions and loads are expressed in terms of the steady-planing characteristics of the seaplane. In order to verify the general validity of these equations, solutions are made for the water landing of a rectangular flat plate and are compared with experimental impact data. Calculated and experimental time histories of draft, velocity, and load are in good agreement. A survey is made of the available information on seaplane planing characteristics which is suitable for use with the analysis of the paper.
