  • Doubly-separating explosively releasable bolt
    Patent number: 10989243
    Abstract: An explosive bolt is provided for securing a brace in tension. The bolt includes a bar, a pair of explosives, a pair of detonators and a pair of anchors. The bar has opposing longitudinal ends and an outer thickness. Opposing bores extend inwardly from the longitudinal ends to corresponding depth ends. First and second notches reduce the thickness proximate to the corresponding depth ends. A center rod separates the notches from each other. Each explosive correspondingly inserts into a corresponding bore to a corresponding depth end. Each detonator correspondingly inserts into the corresponding bore. Each anchor secures the bar to the brace. In further embodiments, the longitudinal ends include helical male threads, and the anchors are nuts having helical female threads.
