Abstract

A uni-directional axial turbine blade assembly comprises a central disc member coupled to an elongated shaft of a motor or generator, a rotational support member mounted on outer circumference of the central disc member, an outer ring mounted on outer circumference of the rotational support member and a plurality of blade members spaced equidistantly, extending radially outward from the outer ring. Each blade member includes a straight leading edge, a curved trailing edge, an exterior surface including a first region having a curved surface, a second region having a flat surface and a convex surface extending from the flat surface and terminating to a radially inward portion and an interior surface including a third region having a concave surface. The preferred embodiment renders the formation of a unique blade configuration that facilitates uni-directional rotation of the blade assembly irrespective of changes in flow direction of fluid.
