Abstract:
1. Wind machine mounted on a vertical mast ( 2 ) and having a wind-driven turbine ( 1 ) which is fitted with blades ( 6 ) mounted on a large-diameter hub ( 7 ) with a horizontal axis, and an alternator co-operating with the turbine ( 1 ) to generate electrical power and which is provided on the one hand with a magnetic rotor ( 4 ) secured to the hub ( 7 ), preferably on a level with the maximum available diameter, and on the other hand a magnetic coil stator ( 5 ) adjacent to the rotor ( 4 ) and secured to a stationary frame ( 22 ) joined to an encircling hood ( 9 ) extending the hub ( 7 ) coaxially to form a streamlined casing in which the alternator is housed, characterised in that the ends ( 55 ) of the blades ( 6 ) are shrouded by a relatively short, divergent, circular fairing ( 8 ), mounted integrally therewith and concentrically with the hub ( 7 ).
