Watercrafts With Active Hulls Attain Substantial Hydrodynamic Drag Reduction

US Patent:
6595815, Jul 22, 2003
Filed:
May 14, 2001
Appl. No.:
09/853685
Inventors:
Ching Yin Au - Greenwich CT, 06831-0905
Lawrence Au - Vienna VA, 22182
International Classification:
B63H 104
US Classification:
440 90
Abstract:
Watercrafts comprising rotatable hulls that serve as propulsors. The hulls are rotors with paddle surfaces and are arranged three-dimensionally to gain the capability of actively diverting water toward the side and the rear, for the purpose of drastically reducing frontal drag and the capability of minimizing friction drag on their wetted surfaces. Watercrafts with rotatable hulls are essentially amphibious.

Personal Marine Transporter Capable Of Offering The Rider The Exhilarating Feeling Of Steering A Very Maneuverable Water Craft By The Direction Of His Body Motion

US Patent:
2011027, Nov 10, 2011
Filed:
May 10, 2010
Appl. No.:
12/800120
Inventors:
Ching Yin Au - Greenwich CT, US
Lawrence Au - Vienna VA, US
Beverly Au - New York NY, US
International Classification:
B60F 3/00
G05D 1/00
US Classification:
440 125, 701 21
Abstract:
A personal marine transporter capable of offering the rider the exhilarating feeling of steering a very maneuverable water craft by the direction of his body motion. Additional features consisting of a handle bar collapsible downward into its housing, a seat with its back rotatable backward and two armrests rotatable forward, reduce the height of the water craft for easy land transportation.

Fluid Forcing Device

US Patent:
5611666, Mar 18, 1997
Filed:
Apr 2, 1996
Appl. No.:
8/626566
Inventors:
Ching Y. Au - Greenwich CT
Lawrence Au - Arlington VA
International Classification:
B63H 137
US Classification:
416 82
Abstract:
A fluid forcing device comprising many rotatable slender elements that converts mechanical energy into fluid energy by mechanically arranging and maintaining, at all times, the rotatable slender elements in a pre-determined wave form and by mechanically moving the wave form in a direction normal to the rotation of the elements.

Fluid Forcing Device With A Fluted Roller Drive

US Patent:
5820342, Oct 13, 1998
Filed:
Dec 16, 1996
Appl. No.:
8/767019
Inventors:
Ching Yin Au - Greenwich CT
Lawrence Au - Arlington VA
International Classification:
F03D 506
US Classification:
416 82
Abstract:
A fluid forcing device comprising many rotatable slender elements that converts mechanical energy into fluid energy by mechanically arranging and maintaining, at all time, the rotatable slender elements in a predetermined wave form and by mechanically moving the wave form in a direction normal to the rotation of the elements by an improved drive comprising two fluted rollers. The new drive reduces the weight and complexity of the entire fluid forcing device and renders it more mechanically rigid and less vibration prone.
