A kite system comprising a kite (14), comprising a gondola (25) and comprising a line tree (24), wherein the kite (14) is joined to the gondola (25) by means of the line tree (24). The line tree (24) comprises a branching block (27, 28). The branching block (27, 28) is connected to the gondola (25) by means of a control cable (35, 36). The line tree (24) comprises a first cable section (48), which extends between the branching block (27, 28) and a first attachment point (61) of the kite (14). The line tree (24) comprises a second cable section (49), which extends between the branching block (27, 28) and a second attachment point (62) of the kite (14). The length of the control cable (35, 36) between the gondola (25) and the branching block (27, 28) is changed by a control mechanism (39). The length of the first cable section (48) between the branching block (27, 28) and the first attachment point (61) is changed by a trimming mechanism (40). The invention also relates to a method for operating a kite system.

Abrégé

The invention relates to a kite system comprising a kite (14), a line tree (24), a gondola (25), and a towing rope (15). The kite (14) is connected to the gondola (25) via the line tree (24), and the towing rope (15) extends between the gondola (25) and an attachment point (16, 55) installed in the ground. A pulling force which is exerted by the kite (14) during operation is transferred via a towing section (15, 24) which extends from the kite (14) to the attachment point (16, 55) via the line tree (24) and the towing rope (15). A separating device (40) which releases upon contacting water is arranged within the towing section (15, 24). The invention additionally relates to a separating device (40) which is suitable for a kite system.

The invention relates to a method for landing a kite system (23). The kite system (23) comprises a kite (14) and a gondola (25), and the kite (14) is held on the gondola (25) via a line tree (24). The gondola (25) is held on an attachment point (16, 44) which is installed in the ground via a towing rope (15) during a normal operation of the kite system (23). A sail surface of the kite (14) is stretched by a first sub-kite (40) and a second sub-kite (41). A connection (36) lying within the sail surface between the first sub-kite (40) and the second sub-kite (41) is separated such that the kite (41) transitions into another aerodynamic state and descends to the ground together with the gondola (25). The invention also relates to a kite system.

The invention relates to a method for converting wind energy into electrical energy, in which method, in a first phase (25) of an operating cycle, a tensile force is exerted on a traction cable winch (16) by means of a kite (14) and the tensile force is converted into a driving force for a power-generating work machine (17) such that the power-generating work machine (17) generates electrical energy, and in which method, in a second phase (26) of the operating cycle, the traction cable winch (16) is driven by means of the power-generating work machine (17) in order to reel in the traction cable (15). The power-generating work machine (17) comprises a first rotor (29), a second rotor (30) in electrical interaction with the first rotor (29), and an axial portion in which the magnetic components of the first rotor overlap with the magnetic components of the second rotor. The first rotor (29) is mechanically coupled to the traction cable winch (16). In the second phase (26) of the operating cycle, kinetic energy of the second rotor (30) is used to drive the traction cable winch (16). The invention also relates to a corresponding device.

A kite system having a kite (14) and a hauling rope (15) which extends between the kite (14) and a tow point (16). A marking holder (25) is disposed between the tow point (16) and the kite (14). The marking holder (25) is conceived for changing between an entrained state in relation to the hauling rope (15), and a free-running state in relation to the hauling rope (15). A fitting installation (31) initiates a changeover between the entrained state and the free-running state of the marking holder (25). The invention moreover relates to a method for operating a kite system.

Abrégé

A method and a system for controlling the winding/unwinding of a rope portion onto/from a rotary drum, comprises the step of making available a rope which is at least partially wound onto a rotary drum, wherein the rope is guided from the rotary drum along a defined path as far as a hauling point, wherein a traction force acts on the rope beyond the hauling point. The method comprises unwinding or winding the rope by executing a rotation of the rotary drum, such that a defined rope portion is moved along the defined path; and determining the length of the defined rope portion in the region of the defined path. The method comprises determining an angle difference corresponding to the rotation of the rotary drum; and controlling the rotary drum for further winding/unwinding taking into account the length and the angle difference. A calibration in the region of the defined path during the use of the rotary drum provides a control for the rotary drum.
