Title:
AIRBORNE WIND POWER GENERATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/065987
Kind Code:
A2
Abstract:
The present invention relates to an airborne wind power generating system. The airborne wind power generating system includes: a first floating body (100) filled with a gas lighter than air so that the first floating body is floated to be airborne, wherein the first floating body includes a main wing (120), a horizontal tail wing (130), and a vertical tail wing (140); a second floating body (200) filled with a gas lighter than air so that the second floating body is floated to be airborne, wherein the second floating body includes a main wing (220), a horizontal tail wing (230), and a vertical tail wing (240); a first pitch angle adjusting unit adjusting the pitch angle of the main wing (120) of the first floating body (100) to control the lift and drag coefficients of the main wing (120) so that the first floating body (100) ascends or descends between a first height (h1) and a second height (h2); a second pitch angle adjusting unit adjusting the pitch angle of the main wing (220) of the second floating body (200) to control the lift and drag coefficients of the main wing (220) so that the second floating body (200) ascends or descends between a third height (h3) and a fourth height (h4); a wire winding unit to which a generator (300) for generating electricity by a rotational force is coupled; a first wire unit (150) having one end connected to the first floating body (100) and the other end wound around the wire winding unit in a first direction; a second wire unit (250) having one end connected to the second floating body (200) and the other end wound around the wire winding unit in a second direction opposite to the first direction; and a control part controlling the first pitch angle adjusting unit and the second pitch angle adjusting unit so that when the first floating body (100) ascends, the second floating body (200) descends, and when the first floating body (100) descends, the second floating body (200) ascends.
