DEVICE FOR MOUNTING AND RELEASE OF SPACECRAFT STRUCTURE MOVABLE COMPONENTS Russian patent published in 2011 - IPC B64G1/22 

FIELD: transport.

SUBSTANCE: invention relates to spacecraft (SC) structure components associated with such its equipment as radar antennas, solar batteries, etc. The device contains immovable section (1) rigidly mounted on frame (2) and two pivotally connected with it movable sections (3, 4). On the lateral sides of the frame (2), two fixing units (7) are mounted each one of which is equipped with two levers pivotally mounted in its body. One of the levers interacts with remote sensor and with long arm of double-arm lever (14) pivotally mounted on stands (15). Short lever (14) arm interacts with long arms of two spring-loaded double-arm levers (16) with pressing regulators (17). The levers (16) interact with remote sensors (18) and short arms - with thrusts (19) on side walls of sections (3, 4). The second lever of the fixing unit (7) interacts with tip of adjustable tie rod cable. The other tip of this cable interacts with pyroholder (26) fixed on the frame (2) via hinged grips fixed in initial position by cotters of corresponding pyrotechnics. Operation of pyroholder (26) is duplicated electrically, mechanically and pyrotechnically. The force required to pull out cotters is reduced by the ratio of arms in two-arm levers and arms in fixing units and pyrohlders. This permits to use low-energy pyrotechnics in the device. In the rotary groups, bushings are installed which provide possibility of swivel elements rotation relative to inner and outer surfaces of bushings. The device has reduced amount of sources of impact impulses acting on electronic equipment, and the sources themselves are at maximum distance from sections of SC movable components.

EFFECT: wider range of SC structure movable components to which this device is applicable with simultaneous increase in SC reliability.
