May 14 2008 Unclassified MotivationMotivation forfor thethe SBFSBF DevelopmentDevelopment • Answer the Fuze’s classical problems • Better safety • Better reliability • One fuze for all decoys and launchers • Programmable electronics • Miniaturization 13 RAFAEL Advanced Defense Systems Ltd. May 14 2008 Unclassified ChallengesChallenges • Flexibility • Compatibility with launchers • Adaptation to Rocket’s Type • Mode of Operation Selection 14 RAFAEL Advanced Defense Systems Ltd. May 14 2008 Unclassified ClassicalClassical ProblematicProblematic AspectsAspects • Low Power / Energy Consumption • Safety • Environmental Conditions • Reliability • Low cost 15 RAFAEL Advanced Defense Systems Ltd. May 14 2008 Unclassified EnergyEnergy ConsumptionConsumption • The current fuze approach – Energized by a limited pulse width – Input capacitance check before launch – Electro-Mechanical pressure switch – Analog electronics design • SBF approach – Energized by the same pulse – Same Input capacitance – Low power electronic pressure sensor – Low power CPU – TI’s MSP430 16 RAFAEL Advanced Defense Systems Ltd. May 14 2008 Unclassified SafetySafety • 2 CPUs in series arming • BIT before launching • Capacitors discharge • S&A Device • Safety delay • Time out – fail safe 17 RAFAEL Advanced Defense Systems Ltd.
