Abstract: A joint that is separable by detonating a detonating cord within an expanding tube. The joint is held together with a set of bolts. Each bolt is retained on one side of the joint with a lever. The expanding tube is retained under an arm of each lever. When the detonating cord is activated, the tube expands and exerts a force against an arm of each lever, thereby breaking the set of bolts, and allowing the joint to separate. In one example, the separable joint is used to retain a payload fairing on a launch vehicle so that the fairing can be jettisoned during flight.
