AI Technical Summary

Technical Problem

Current kite systems experience inefficiencies due to the need to steer the kite to the edge of the wind window for retrieval, resulting in time and energy losses, as the wind force is weaker at the edge, necessitating a method to maintain high pulling power within the wind window.

Method used

A kite system with a coupled control mechanism and trimming mechanism that allows the kite to change its angle of attack and flight path without adapting the control mechanism, enabling it to fly within the wind window while maintaining control, and includes a mechanism to adjust the length of tension cords between articulation points to induce rolling and pitching movements, allowing the kite to curve and pitch while maintaining control.

Benefits of technology

Enables the kite to be retrieved quickly and efficiently within the wind window, reducing energy expenditure and time, while maintaining control and aerodynamic performance, allowing for high-speed retrieval and stable flight.

Abstract

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.
