TRIPPED UNLOCKING DEVICE, CONNECTING TWO DETACHABLE SUBASSEMBLIES

摘要

A device for rapidly separating two subassemblies under the action of a pyrotechnic gas generator. The device comprises a segmented nut (17) held by a release sleeve (40) that is movable under the action of the gas generator (15), a drive chamber (64) including an end wall of the release sleeve, a damping chamber (66) communicating with a gas expansion chamber (60), and calibrated passages (70) extending between the damping chamber and the drive chamber.
