An Investigation of the Hydrodynamic Characteristics of a 1/10-Size Powered Dynamic Model of the Martin M-267 Patrol-Type Seaplane with Two Forebody Configurations: TED No. NACA DE 376

Description: Report presenting an investigation of the hydrodynamic characteristics of a scale powered dynamic model of a patrol-type seaplane designed by the Glenn L. Martin Company. The seaplane had a high-aspect-ratio wing and a T-tail with an all-movable stabilizer. A comparison was made between two forebody configurations, one with a sharp forebody keel in cross section and the other with the forebody cross section rounded in the vicinity of the keel.
