ABSTRACT:
A pyrothechnic actuated structural release device which is mechanically two fault tolerant for release. The device comprises a fastener plate 11 and fastener body 12 each attachable to one of a pair of structures to be joined. The fastener plate 11 and the fastener body 12 are fastenable by a dual swivel toggle member 13. The toggle member is supported at one end on the fastener plate and mounted for universal pivotal movement thereon. Its other end is received in a central opening in the fastener body 12, and has a universally mounted retainer ring member 38. The toggle member 13 is restrained by three retractable latching pins symmetrically disposed in equiangular spacing about the axis of the toggle member 13 and positionable in latching engagement with the retainer ring member on the toggle member. Each pin is retractable by a pyrotechnic charge, the expanding gases of which are applied to a pressure receiving face on the latch pins to effect retraction from the ring member. While retraction of all three pins releases the ring member, the fastener is mechanically two fault tolerant since the failure of any single one or pair of the latch pins to retract results in an asymmetrical loading on the ring member and its dual povotal movement ensures a release.
