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

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
