HIGH-ALTITUDE-WIND TURBINE WITH AUTONOMOUS WINGS VERTICAL AT TAKEOFF

Publication No.: EP4062052A1 28/09/2022

Applicant:

MILLER BERNHARD [DE]

DE_102020130800_PA

Absstract of: WO2021099590A1

The invention describes a wind turbine for generating power by means of high-altitude winds. Said wind turbine is held by one or more long guy cables. The wind turbine consists of several individual wings, which are connected to one another only by cables. Each wing of the wind turbine has two electrically driven propellers which are supplied by a battery. Thus each wing can fly independently, thereby achieving a very high operational reliability. During takeoff and landing, the airfoils of the wings are vertical and can take off and land vertically in a manner similar to a multicopter. The wings then pivot into horizontally rotating operation. Several wind turbines can be connected to one another by cables and fly together as a group of wind turbines. In order for the wind turbine to take off and/or land, each wing 1 is oriented according to the current wind strength and wind direction, by a wing holding robot 2. As a result, safe takeoff and landing is ensured, even in difficult wind conditions, without significant correction to the orientation of the wing.
