Abstract: An improved pulley for winch is described, in contact with at least one section of rope included between an inlet section, connected to a working load, and an outlet section, with minimum or null tension, such pulley comprising a kinematic chain composed of peripheral supports.

Abstract: An infrastructure for tropospheric aeolian generator is described, which comprises a rotary basement (1), at least one orientable arm (2), at least one ventilation plant (3), at least one system (4) for supporting at least one wing (7), and a driving system (5) of control cables (6) of the wing (7).

Abstract: A rope (3) is described for a tropospheric aeolian generator (1) composed, in length, of at least one first sector (4) adapted to resist to repeated flexure cycles, having a safety coefficient (S1), a diameter D(b1) and an aerodynamic resistance coefficient (CD1); at least one second sector (5) adapted to resist to repeated traction cycles with great load, having a safety coefficient S2<S1 and a diameter D(b2)<D(b1).

Abstract: A system (10) is described for performing the automatic control of the flight of at least one kite (11) controlled and driven by cables (13) comprising at least one first actuating motor (12) adapted to exert an unwinding-rewinding action of such cables (13) on respective winches (14a, 14b) and at least one second actuating motor (15) adapted to perform a differential control action of such cables (13).

Abstract: An aeolian system is described for converting energy comprising at least one power wing profile (30) which can be driven from the ground immersed in at least one aeolian current (W) and a basic platform (1) for controlling the wing profile (30) and generating electric energy placed at ground level and connected through two ropes (2) to the power wing profile (30), such basic platform (1) being adapted to drive the wing profile (30) and to generate electric energy, such two ropes (2) being adapted to transmit forces from and to the wing profile (30) and to be used both for controlling a flight trajectory of the wing profile (30) and for generating energy. A process is further described for producing electric energy through such aeolian system.
