ABSTRACT:
A wind turbine cross wind machine is disclosed, which comprises a circumferential arrangement of guide vanes (1) around a centrally located rotor (2) including a central aperture (3) in the middle of a circumferential arrangement of blades (2), where the guide vanes are capable of guiding the wind falling upon counter acting rotor blades towards the direction of rotor rotation, whatever direction the wind may be coming from, thereby offering a substantial improvement in this wind machine efficiency.
Alternatively, the guide vanes (2 in FIG. 7) being of a uniform airfoil type they divert the airstream path by acting like an aerodynamic lens causing a uniform concentration of it within the encircled area, thus producing twin symmetrically convergent airpaths passing through the engine and causing a horizontal venturi effect to appear across the rotor blades with advantageous results on engine performance.
