Abstract

A fluid driven turbine includes a central rotor having a plurality of wind blades mounted circumferentially around the axis of the rotor and arranged to define a general spiral configuration extending along the axis of the rotor in a predominant fluid flow direction. The hub is spherically shaped to force the fluid outward with an increase in velocity into engagement with the blades.

Claims

1. A fluid turbine rotor comprising:

a central hub having a generally spheroid configuration mounted for rotation about an axis;

a plurality of forwardly curved self supporting wind blades having a base and an outer tip and mounted at said base on said hub,

said wind blades each having a relatively wide base tapering down substantially to a point at the outer tip, each blade curving and extending forwardly along said axis with increase in radius from said base to said point at said outer tip with said tip positioned forward of said base with said tip pointing substantially parallel to said axis.

2. The fluid turbine of claim 1 wherein said rotor has a prolate spheroid configuration and said blades are secured to one end of the rotor and projected radially outward and axially forward at the outer tips.

3. The fluid turbine of claim 2 wherein said hub has a nose portion that extends outward from the rotary axis to at least one-half the radius of the rotor.

4. The fluid rotor of claim 2 wherein said blades are curved forward along said axis terminating at the outer end in said forwardly projecting tips extending beyond the forward end of said hub.

5. The fluid turbine of claim 2 wherein the blades of said rotor have an outer surface that defines a substantially parabolic configuration in side elevation.
