METHOD OF FORMING FRAMELESS CENTRIFUGAL STRUCTURE (VERSIONS) AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2007 - IPC B64G1/22 B64G1/44 

FIELD: centrifugal frameless structures formed in space and used for deployment of solar batteries, reflectors and other large-sized systems.

SUBSTANCE: proposed method includes placing the flexible sectors on carrier, rotating the carrier in plane corresponding to working position of frameless centrifugal structure and deploying the sectors from carrier under action of centrifugal forces. Sectors are interconnected by side edges forming single working surface in the course of their deployment and preliminarily when necessary. Additional deploying force is applied to sectors along joint areas from periphery of centrifugal frameless structure to its center. Device proposed for realization of this method has carrier for placing the sectors, its rotation drive, as well as drive and mechanism for extension of sectors. Articulated on bearing part of extension mechanism are brackets provided with pairs of hold-down and drive rollers. One sector joint area is passed through each pair of roller. Drive roller is provided with drive which is kinematically aligned with sector extension drive, thus forming additional deploying force. Side edges of sectors may be connected at points of application of this force (or near them) with the aid of connecting elements, such as zipper, as well as by welding, bonding, sewing, etc. Carrier may be made in form of common drum or in form of reels separate for each sector. Device forming the centrifugal frameless structure has surface smoothly stretched in two axes.

EFFECT: enhanced reliability; facilitated procedure.
