Title:
水上機艇体
Document Type and Number:
Japanese Patent JP3662024
Kind Code:
B2
Abstract:
A seaplane hull has a high length/beam ratio, substantially fair topside waterlines from bow to stern and a fine bow entry angle. These characteristics disperse the water little, offering the hull low wave-making drag characteristics which enable it to achieve high speed without requirement for planing lift. Chines (4) on the underside describe a slim planing surface, the edges converging aft toward the central plane. The slim planing surface minimises wetted area at speed, and low pressure hollows (6) are provided immediately above the chines (4) for air to travel aft and under an afterbody when at speed. The design enables continuity of aerodynamic and hydrodynamic streamlines throughout acceleration to take-off speed.
