SPACECRAFT UMBRELLA ANTENNA Russian patent published in 2011 - IPC H01Q15/00 

FIELD: physics.

SUBSTANCE: device consists of a radiator and an opening reflector, having a central unit which is pivotally joined to a bearing frame in form of spokes, a hub attached to the central unit on the opposite side of the opening of the reflector, a device for adjusting the shape of radio-reflecting surface of the reflector, output elements of which are in form of bolts, joined by the "bolt-nut" transmission with each guy wire and a specific transmission bolt during operation, mechanically connected to the output shaft of the electromechanical drive of the device. The technical result is achieved owing to that the mechanical interface between the specific bolt and the output shaft is in form of a turning platform, joined by toothed bevel gear with the output shaft of the drive. In tension mode or release of a specific guy wire, the clutch is mechanically connected to the corresponding functioning bolt, and said bolt is mechanically connected through the toothed bevel gear with the output shaft, and when the platform turns, the bolts are mechanically disconnected with the output shaft. Said output shaft is mechanically connected to the turning platform through the toothed bevel gear.

EFFECT: easy control.
