Abstract
A missile severance device for severing a structural surface member of a body is constructed of a pair of plate members separated by a collapsible liner member ring. An explosive charge is contained with the volume defined by the pair of plate members and the liner member ring. One of the plate members includes a booster explosive charge that serves to detonate the explosive charge so as to collapse the liner member ring and create a directed jet toward the structural surface member intended to be cut.
Claims11
A missile severance device for circumferential severance of missile sections when mounted within a missile defined by a body having a central longitudinal axis surrounded by a missile skin, the missile severance device comprising:
- a booster plate member having a generally central aperture containing a booster explosive charge therewithin, said booster plate member rigidly coupled to said missile body with said central aperture generally aligned longitudinally with said central longitudinal axis of said missile, and with peripheral edge portions thereof proximate said missile skin intended to be severed;
- a cover plate member;
- an explosive cutting charge sandwiched between said booster plate member and said cover plate member, and in contact with at least central portions of said booster plate member and said cover plate member;
- a liner member constructed so as to have a collapsible thickness, where said liner member substantially surrounds peripheral portions of said explosive cutting charge, and extends generally between said booster plate member and said cover plate member;
- and
- means for rigidly securing said booster plate member to said cover plate member and sandwiching said explosive charge and said liner member therebetween.

- an explosive cutting charge sandwiched between said booster plate member and said cover plate member, and in contact with at least central portions of said booster plate member and said cover plate member;
- a generally ring-shaped liner member surrounding peripheral portions of said explosive cutting charge and extending generally between said booster plate member and said cover plate member, said ring-shaped liner member having a generally V-shaped cross-section having an apex thereof directed radially inward toward said explosive cutting charge, and
- means for rigidly securing said booster plate member to said cover plate member and sandwiching said explosive charge and said ring-shaped liner member therebetween.
