A wind power generator has an arcuate converging-diverging flow passage and a support body that is prolate in shape and is located in the flow passage. The support body is rotatably supported and a plurality of rotor blades are mounted on the support body. The support body and the flow passage define a converging-diverging flow area through which wind passes to drive the support body via the rotor blades.

What is desired to be secured by Letters Patent is: 1. A wind power generator comprising: a) a support element; b) an outer casing mounted on said support element, said outer casing having a first end which is a fluid inlet end when said outer casing is in use, a second end which is an outlet end when said outer casing is in use, a central axis extending between the first end and the second end, and a central plane located midway between the first end of said outer casing and the second end of said outer casing and extending perpendicular to the central axis, said outer casing further including (1) an outer surface, the outer surface being circular in shape with a plurality of planar facets thereon, the facets extending in the direction of the central axis of said outer casing, and (2) an inner surface, the inner surface being arcuate in shape and being oriented to be convex with respect to the central axis of said outer casing, the inner surface having a single radius of curvature and being smoothly curved between the first end of said outer casing and the second end of said outer casing, the curvature of the inner surface being shaped to define a flow area with the flow area steadily and smoothly decreasing from the first end of said outer casing to the central plane of said outer casing and then steadily and smoothly increasing from the central plane of said outer casing to the second end of said outer casing, the inner surface being shaped such that a line tangent to the inner surface at the first end of said outer casing is oriented at 45째 with respect to the central axis of said outer casing and a line tangent to the inner surface at the second end of said outer casing is oriented at 45째 to the central axis of said outer casing whereby the flow area defined by the inner surface converges between the first end of said outer casing and the central plane and then diverges between the central plane to the second end of said outer casing; c) a plurality of support struts having a first end and being fixed to the inner surface of said outer casing adjacent to the first end and a second end located adjacent to the central axis of said outer casing, said support struts being located at the central plane of said outer casing, at least one support strut of said plurality of support struts having a first end fixed to said outer casing; d) a support body rotatably mounted on said support struts adjacent to the second end of each support strut, said support body having an arcuate outer surface that is prolate in the shape and which has a single radius of curvature, said support body having a first end which is located adjacent to the first end of said outer casing and a second end which is located adjacent to the second end of said outer casing, said support body further including a long axis that extends between the first end of said support body and the second end of said support body and is co-linear with the central axis of said outer casing, said support body further including a small axis that is oriented perpendicular to the long axis of said support body and is located adjacent to the central plane, the small axis being spaced apart from the central plane towards the first end of said outer casing, said struts being rotatably connected to said support body adjacent to the small axis of said support body and spaced apart from the small axis in the direction of the second end of said outer casing, the support body being spaced apart from the inner surface of outer casing, the support body and the inner surface of said outer casing defining a flow passage which smoothly converges between the first end of said support body and the central axis of said outer casing and then smoothly diverges between the central axis and the second end of said support body with the flow passage being sized to be a minimum flow area at the central axis of said outer casing; e) a control rudder mounted on the second end of said support body, said control rudder including (1) a support rod having a first end fixed to the second end of said support body and a second end spaced apart from the second end of said support body, the support rod being co-linear with the central axis of said outer casing, and (2) a control tail mounted on the second end of said support rod; f) a plurality of rotor blades mounted on said support body, each rotor blade of said plurality of rotor blades having a first end fixedly mounted on said support body adjacent to the small axis of said support body and a second end spaced apart from said support body and spaced apart from the inner surface of said outer casing, said rotor blades extending radially outward from said support body and being spaced apart from the small axis of said support body in the direction of the first end of said support body to be located between the small axis of said support body and the first end of said support body; and g) a power generator connected to said support body and converting rotational movement of said support body into power. 2. The wind power generator as described in claim 1 wherein the inner surface of said outer casing includes a plurality of sections with each section extending between the first end of said outer casing and the second end of said outer casing.
