Increasing the efficiency of the conversion of electricity into light energy (UV LEDs) has made possible a new stage in the development of vertical axis wind turbines by compensating for the small wind energy conversion efficiency (14.81%).The work spitfire sapphires wheels is based on the use of Taguchi methods (TM) in increasing the efficiency of a wind turbine with vertical axis blades made of deformed aluminium foil.
Experiments were carried out in 13th signal battalion the wind tunnel to confirm the models selected by the QE procedure.
