A GRAPHICAL METHOD FOR INTERPOLATION OF HYDRODYNAMIC CHARACTERISTICS OF SPECIFIC FLYING BOATS FROM COLLAPSED RESULTS OF GENERAL TESTS OF FLYING-BOAT-HULL MODELS

摘要

This report presents a simple and rapid method for interpolating the hydrodynamic characteristics of specific flying boats from a chart presenting test results in collapsed form. The method is graphical and will allow Interpolation of the hydrodynamic character¬istics for any combination of load or aerodynamic characteristics. To obtain the water resistance and porpoising characteristics of one specific case requires about 20 or 30 minutes' work. It is believed that the rapidity with which interpolations may be made will open up the way for comprehensive design studies of the influence of various factors on flying-boat performance.
