Abstract

A power kite and a bridle system is adapted to connect the power kite to a control box. The power kite includes a leading edge and a trailing edge, and the bridle system includes multiple power lines and at least two steering lines. The steering lines are connected to zones including wingtips of the power kite such that a steering angle of the power kite is controllable by balancing the steering lines. The multiple power lines comprise a front line connected to a front zone of the power kite including a central part of the leading edge and comprise a back line connected to a back zone of the power kite including a central part of the trailing edge, such that an angle of attack of the power kite is controllable by balancing the front and back lines.
