Abstract
An explosive separation joint system having an expandable tube containing a mild detonating fuse (MDF) in separable portions of the joint. The MDF extends into a detonation manifold at a first port, an end of the MDF having booster bonded thereto. An external initiating ordnance transfer line enters the manifold at an initiating ordnance (IO) port, has an IO end tip and provides a detonation impulse train where each detonating component is axially aligned within a passageway with the next detonating component. In embodiments, particular detonating components of the detonation train are fixed in place where other detonating components are movable. Each detonating component that is not in direct contact with a preceding detonating component in the detonation train is in direct linear access.
