DEVICE FOR CONTAINMENT AND RELEASE OF EXPANDABLE ELEMENTS OF SPACECRAFT DESIGN Russian patent published in 2017 - IPC B64G1/64 

FIELD: aviation.

SUBSTANCE: device comprises a separated part and a stationary part. The separated part comprises a cover with a hole for pin (4), a nut (5), a spring (6), a washer (7) and other elements. The stationary part comprises a housing, a washer, rollers (14) which interact with sliding blocks and rollers (15) which interact with a conical portion of the pin (4), a rotational spring (16), a separation sensor (20) and other elements. The stationary part housing is attached to the spacecraft housing. The washer which rotates the rollers (14) is released and turned by the spring (16) during the separation of separated and stationary parts due to the pyro firing. The rollers roll over the inner surface of the washer and over the surface of the sliding blocks - untl the release of sliding blocks (for their rotation in the axes (19)) and rollers (15) (for releasing the pin (4)). The pin is pulled out of the stationary part housing to the separated part cover by a spring (6). The sensor (20) is activated due to the movement of the sleeve (21). A spring (22) in the sleeve (21) and a shaft positioned between the separated part cover and the stationary part housing are designed to prevent jamming during the separation.

EFFECT: higher reliability of release of spacecraft expandable elements, size reduction and increased informativity of the device.
