Title: Safe rocket motor igniter using sequenced initiation to an explosive logic network

Abstract: An apparatus for providing ignition of rocket motors by using sequenced iiation to an explosive logic network that is fail safe in case of accidental initiation. The explosive logic network has a multiplicity of input detonators for ignition of the explosive logic in a predetermined time program which must be accomplished in a specific ignition sequence to achieve a single explosive output to ignite the rocket motor squib and fire the motor. A deviation from the predetermined timed sequence or ignition of one or more of the input detonators will dud the system causing a fail safe condition of the logic network that prevents rocket motor ignition.
