An Investigation of the Hydrodynamic Characteristics of a Dynamic Model of a Transonic Seaplane Design Having a Planing-tail Hull

Résumé du livre

An investigation was made of the hydrodynamic characteristics of a 1/17-size dynamic model of a 160,000-pound transonic seaplane design having a planing-tail hull with the center of gravity located 2.1 beams aft of the step. Longitudinal stability during smooth-water take-off and landing was satisfactory, and the landing behavior in waves was good. These results were similar to that of a previously tested planing-tail-hull model having the center of gravity slightly aft of the step. The thrust from currently available engines was sufficient to accelerate to take-off in 20 seconds in a distance of 2,530 feet (full-size) with a gross load of 160,000 pounds, and in 34 seconds in a distance of 4,320 feet with a gross load of 200,000 pounds. Spray characteristics were very good in smooth water and in waves.
