A wind powered turbine is comprised of a frame on which is horizontally and rotatably supported a rotor on a rotor shaft. The rotor is formed by three or more radial blade members which are secured to the rotor shaft. The radial blade members are equidistantly spaced from one another and each have support arms and a wind vane secured at an outer end portion of the support arms. The wind vane is shaped to capture an airflow directed thereagainst for displacement thereof to create a rotational force about the rotor shaft to rotate the shaft about its longitudinal central axis. The radial blade members are rigidly interconnected to one another at an outer end portion thereof by tension adjustable bracing tie wires. A wind channeling guide assembly accelerates and directs the airflow in an actuating airflow path to impinge upon at leas of the wind vanes positioned in the actuating airflow path.
