An Investigation of Effects of Reversed-Type Longitudinal Steps on Resistance and Spray Characteristics of a Flying-Boat Hull

Arthur W. Carter, Eugene P. Clement, Alvin H. Morewitz

Abstract

Report presenting an investigation of a flying-boat-hull model to determine the effects on the resistance and spray characteristics of reversed-type longitudinal steps designed so that the surfaces of the steps normal to the hull bottom face inboard. Results of the tests were compared with results of a conventional flying-boat-hull model. No appreciable improvement in the resistance or spray characteristics near the hump speed was noted.
