ABSTRACT:
A separation device (23a-23d) comprises a frangible joint (24a-24d) comprising joinder flanges (27a, 27b) interconnected by walls (126a, 126b, 226a, 226b, 326a, 326b, 426a, 426b) having fracture grooves (28a, 28b) and defining a channel (36a-36c) therein. Within the channel (36a-36c) is disposed an expansion member (10, 10a, 10b) containing a detonation charge (16) and having expansion regions (34a-34c, 134a, 134b) that expand upon detonation of the charge (16). The expansion region bears against walls at the junctions (32a, 32b, 32b', 132a, 132b, 232a, 232b) thereof with joinder flanges (27a, 27b) to provide separation thrust as well as causing frangible joint (24a-24d) to fracture at fracture grooves (28a, 28b).
