Redundant, Confined-Explosive Severance Device
Abstract
Noncontaminating, long, explosive joint with highly reliable separation capability invented for such applications as separation of rocket-motor stages of spacecraft from rockets or Space Shuttle. Two explosive cords housed in tubes held in place by two notched doublers and commercially available fasteners. When either cord fired, its tube expands, bending doublers and causing fracture at adjacent notch.
