SOLAR CELL PANEL FOR SPACECRAFT Russian patent published in 2012 - IPC B64G1/44 

FIELD: physics.

SUBSTANCE: invention relates to spacecraft electric power supply systems and specifically to solar cell panels. The solar cell panel comprises two panels, each consisting of two half-panels, having pivotally connected and series-assembled into a bundle a root (2), middle (3) and an outermost (4) flap. The flaps are mounted on a frame (5) which is movably mounted on four mounting assemblies (6) of the body (1) of the spacecraft. The half-panels are connected to each other on one side by four spring-loaded clamps (7), and on the other by four couplers (8) in the mounting assemblies (6). The root flap is connected to the middle flap by an axle (9) and the middle flap is connected to the outer most flap by an axle (10). The spring-loaded clamps are connected by a rope to a pyro device (not shown). Two supporting arms are mounted in pairs on each flap. The supporting arms mounted on the outermost flap are provided with axles which interact, when opening the panels, with profiled protrusions on the supporting arms mounted on the root flap. This enables to open the panels using a "roll" technique, wherein there is organised retraction of flaps, which prevents their collision with spacecraft equipment when opening. The number of pyro devices in locking elements of the panels is reduced.

EFFECT: high reliability of spacecraft with solar cell panels.
