Title:
DEVICE FOR CONTROLLING AND STEERING TRACTION KITES OR ROTATING FLYER WHEELS FOR ELECTRICITY GENERATION
Document Type and Number:
WIPO Patent Application WO/2015/165913
Kind Code:
A3
Abstract:
The invention relates to a traction kite control system that allows precise and reliable positioning of traction kites or rotating flyer wheels. Normal traction kites have 2 to 4 traction ropes for steering. In the device according to the invention, the pulling force should be adjustable in addition to the steering. To minimise the number of ropes, a plurality of traction kites are connected by means of connecting ropes (3) to form a group. Each individual traction kite within said group has only 2 traction ropes for transmitting and controlling the pulling force of the traction kite. The individual traction kites are connected to each other in a net-like manner by means of connecting ropes (3). To control the position of the respective group of traction kites or flyer wheels, positioning traction ropes (4), which run obliquely downwards, are braced at the outer traction kites in a similar manner to a known domestic tent. The traction ropes (5) then virtually assume the function of known tent bars. The traction kite group can also execute horizontal movements in the form of a horizontal figure of eight or also circular movements. Then only the individual screens rotate according to the movement direction and/or wind direction with the aid of rotary bearings (8) and rope rotators (9). The wind direction can be determined by comparative measurement of the individual pulling forces and lengths of the respective positioning traction ropes. By changing the relative pulling force compared with adjacent screens and the traction ropes, the position of the traction kite group can be adjusted to the wind direction and/or the desired movement direction. The distances between individual traction kite groups can then be minimised.
