LIGHT-AND HEAT SHIELDING DEVICE OF SPACECRAFT AND METHOD OF ITS OPENING AND STABILIZATION Russian patent published in 2019 - IPC B64G1/52 B64G1/58 

FIELD: astronautics.

SUBSTANCE: group of inventions relates to protection of spacecraft (SC) structures from outer space factors. Proposed device comprises screen and retainer. Screen has a flexible structure (FS) made of heat-resistant laying glass fabric and aramide fabric impregnated with epoxy-phenol binder. Screen-vacuum insulation and temperature-regulating films, as well as stiffness elements, are fixed on FS surfaces. For opening one side of FS is fixed to spacecraft and preliminarily swirled (for example, by bending by half-turn). Second side of FS is retained by said device, after actuation of which free FS is opened under action of bending moment and then stabilized by residual moment in position of screen. Process is controlled by sensor. Damper is installed to exclude impact at opening in contact point of shield from spacecraft.

EFFECT: reduced weight and simplified design of protection device of spacecraft from radiant and heat action due to exclusion of special drives, hinge devices and locking mechanisms.
