Abstract: In a missile assembly (or the like) including a motor nozzle positioned in a central portion of a rear surface of the missile and a sustainer motor positioned a distance away from the rear surface of the missile, the invention comprising a blow pipe joining the sustainer motor and nozzle assembly, with the blow pipe including a portion extending along an axis which is eccentrically positioned with respect to the longitudinal axis of the missile.

Abstract: An improved device for breaking the connection between an electric control system and a missile by separating a control cable or umbilical cord joining the missile to its launcher housing during launch. A plurality of continuous, flexible conductors are passed through openings in a non-conductive insert in the surface of the missile. Because the conductors are secured to both the missile and the housing on opposite sides of the insert, they are tensioned against and bent over the outer edge of the opening during launch and broken due to the concentration of tensile and bending stress at the point of contact.
