SPACECRAFT LIGHT PROTECTION DEVICE Russian patent published in 2010 - IPC B64G1/52 B64G1/58 

FIELD: transport.

SUBSTANCE: invention relates to safety device of spacecraft. Proposed device comprises frame (1), cover made up of two flaps (2) coupled with their rotation drives, two locking mechanisms, electric drive, turn angle transducer, flap emergent open mechanism and limiters of flaps extreme positions (17). Turn angle transducer is arranged with clearance in shielded casing and represents a rotor (9). One end of rotor shaft interacts with electric drive shaft and another end interacts with bell crank (12) of articulated lever mechanism (ALM). The latter comprises also tie rods (13), spring compensators (14) and control levers (15). Rotor (9) is furnished with magnets interacting with tight contacts on shielded casing. Compensator spring (14) is arranged between two conical tips with their conical surfaces interacting with casing of compensator (14), jointing element and mating conical surfaces on fastening elements. Shafts of mechanisms of flaps emergent opening have their end coupled with ALM output shafts and another end interacting with active levers of flaps (2) for coupling with flaps rotation drives. Said levers interact, in their turn, with stops (17) incorporated with said rotation drives. Flaps passive levers interact with said stops (17) arranged on the other side of flaps.

EFFECT: higher reliability.
