The invention relates to a turbine whose axis (1) turns vertically and to which are connected in a radial way, holders (2,3) for the blades (12,13) made up by metallic frames surrounding an area materialized by a textile canvas. The blades turn over themselves synchronically with the turbine by means of a set of cogwheels (8) in order to display the most favourable position for a maximum thrust of the wind (14). The safety devices work by the loosening of one side of the canvas and by the automatic rolling on the respective roller rod (15,16), when the pressure of the wind surpasses a predetermined value. |
