Wind Driven Power Plant

View page
US Patent:
44115881, Oct 25, 1983
Filed:
Feb 20, 1981
Appl. No.:
6/236269
Inventors:
Walter E. Currah - Tacoma WA
International Classification:
F03D 104
US Classification:
415 2A
Abstract:
A system for the conversion of wind energy to electric energy includes means for converting prevalent energy winds by use of the following: a "collecto-fin" that includes, from front to rear, a surface of a frustum of a right circular cone and one or more thin, flat circular rings to provide a difference in total pressure between the front and rear surfaces; an inner "stream-liner" that includes, from front to rear, a surface of a right circular cone, a surface of a cylinder, and a surface of a frustum of a right circular cone to conform to the slipstream boundary of the wind; an outer "stream-liner" that includes, from front to rear, a surface of a frustum of a right circular cone, a surface of a cylinder, and a surface of a right circular cone to conform to the slipstream boundary of the wind; and a wind turbine to conform to slipstream boundaries.

US Patent:
44511990, May 29, 1984
Filed:
Nov 7, 1980
Appl. No.:
6/204810
Inventors:
Walter E. Currah - Tacoma WA
International Classification:
F03D 104
US Classification:
415 2A
Abstract:
A structural support system for a wind driven power plant includes a plurality of circular support frames that are supported relative to a stationary foundation by support columns. The support frames are mounted coincident with and spaced along a support-system longitudinal axis with each frame having a circular inner and a circular outer support ring. Axially directed stringers are connected to and extend between respective inner and outer support rings with associated stiffners to provide a structurally enhanced framework for supporting wind driven power plants. The support columns are preferably hinged to the foundation to permit the columns to be fabricated at ground level and pivoted into an upright position for connection to the associated support frames to provide the completed structure.
