Embodiment Construction

[0057] refer to figure 1 , a tropospheric wind generator 1 according to the invention can be seen schematically with two ropes 3 capable of reaching a length of about tens of thousands of meters to control and transmit mechanical energy from the kite 2 to the generator 1: in particular, with The rope 3 of the present invention in the tropospheric wind power generator 1 constitutes as follows in length:

[0058] - at least one first zone 4 optimized to resist repeated bending cycles, especially preferably made of a synthetic fiber mixture with a high modulus of elasticity, and having a diameter D by employing a safety factor S1 between 3 and 15 (b1) and the aerodynamic drag coefficient C D1 To design the size, the safety factor S1 is the ratio between the static ultimate tensile strength of the rope and the maximum load provided during operation, and the diameter D (b1) is usually between 6mm and 72mm, preferably between 8mm and 72mm Between 48mm;

[0059] - at least one sec...

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 anda diameter D(b2) < D(b1).

Description

technical field [0001] The invention relates to a rope for a tropospheric wind power generator. Background technique [0002] A new type of tropospheric wind generator is known in the state of the art and is currently being developed by different research groups with the common goal of operating at high altitudes by means of long ropes with high mechanical resistance. Large amounts of wind energy are exploited limited to kites, wings, flying machines, aircraft and airships on the ground. [0003] The general operating principle of tropospheric wind generators is based on keeping in flight an aerodynamic body capable of converting wind energy at high altitudes into mechanical energy capable of performing work, and subsequently, converting the mechanical energy into Electrical energy for domestic and industrial use. [0004] In its simplest, most efficient and safe configuration, an aerodynamic body can simply be a highly aerodynamically efficient wing, capable of flying at ...
