Abstract : This patent discloses a pyrotechnic ignition train for use in dual nozzle rocket-ramjet missiles wherein a donor device and a receptor charge in the train allow transfer of a pyrotechnic impulse across an air gap between an outer nozzle and an inner concentric nozzle to allow ignition of the rocket motor. Upon consumption of the rocket fuel the inner nozzle is jettisoned, and the ramjet motor fired. Absence of physical connection of the nozzles at the ignition train allows easy separation of the inner nozzle from the missile.
