SEPARATION BOLT WITH OBTURATION SYSTEM Russian patent published in 2019 - IPC F16B31/00 F42B15/36 B64G1/64 

FIELD: astronautics.

SUBSTANCE: invention relates to space engineering, particularly, to separation bolts. Separation bolt for connection and subsequent fast disconnection of structure elements as per instruction includes power casing, charge and electric detonator. Fire circuit of the latter consists of: electric igniter with active charge, shutter and detonating cap of radiation action, into which charges of initiating substance and brisant explosive substance (BES) are successively pressed. Obturator, which is a metal bushing with an internal channel, is installed in the power housing on the thread. Application of detonating cap in end part of obturator and formation of variable cross-section inside channel provides for obturation of products of explosive transformation formed at operation of BES charge. BES charge has gap with detonating cap bottom not more than 4 mm.

EFFECT: enabling higher reliability.
