BENCH FOR OPENING PANELS OF SOLAR BATTERY Russian patent published in 2013 - IPC B64G7/00 B64G1/44 

FIELD: transport.

SUBSTANCE: invention relates to ground tests of opening structures, predominantly solar batteries (SB) with null-gravity conditions simulation. The bench is designed for opening two dissymmetrical SB panels (1) and contains frame leg (2) on which weight-releasing device (3) is mounted and adapter frame (4) for spacecraft simulator (5). In the upper part of leg (2), bracket (6) is installed. The bracket is moved horizontally. In the lower part of leg, adjustable pillars (8) are installed. Device (3) is made as separate swivel links (9) where bracket (6) is rigidly connected with the first link. Rotation axes of links are coaxial to rotation axes of corresponding SB panels (1). The latter is provided by moving the bracket (6) manually along guides and by fixing it with special screw. In each link (9), two dampers in the form of rods (not shown) are fixed. During SB testing for opening connection with board (5) is released and SB (1) flaps begin to open under action of operational springs. As gap between SB (1) flaps and device (3) is limited (not more than 150 mm) the presence of the said dampers with hangers has little altering influence on calculated flap movement, and their rigid connection in the form of rods provides synchronous movements of SB (1) flaps and the device (3).

EFFECT: widening of bench operational functionality, as well as maximum approximation of SB flaps opening conditions to null-gravity conditions.
