A little bit of (Fuze) History

Definition: “A Fuze is a Device that initiates an Explosive Function.”

• 1990s, Sensor Fuzes

• 1980s, Electronic Multifunction Fuzes

• 1940, Proximity Fuzes [called VT-, variable time-]

• 1650, Percussion Fuze

• 1421, Time Fuze – pyrotechnical – [Siege of St. Boniface in Corsica]

• Solid cannon balls did not need a fuze

Power Supply

All new electronic Subsystems are

• Low voltage 1.7 - 8.5 V*

• Low current 5 - 110 mA*

Low power 10 - 300 mW*

Typical combinations for medium caliber

PPeak = 50 - 500 mW

flight times of 10 - 20 sec sum up to E = 0.5 - 10 J

Sophisticated Power management is required to lower Energy

* for the examples shown

Set-Back-Generators are far too small for these applications

Miniaturized Fuze Batteries can do *

TEPS plus a moderate size capacitor can do *

* See #16520

Other Hurdles

All examples shown are commercial temperature range, -40°C ÷ 80°C

Fuzes are usually -46°C ÷ 63°C (C2, AECTP 200)

How critical is the gap of -6°C

• geographically (colder areas)

Northern Norway (Scandinavia)

Prairie provinces of Canada

Tibet

Much of the (former) USSR

We see various ways to solve this issue !

Summary

Electronic Fuzing can significantly enhance Effectivity of Future Munition

Everyday Commercial Electronic Systems

demonstrate the functions which can be achieved today

almost no limits

Electronic Commercial Subsystems are suitable

for very advanced fuze functions

Power Supplies with the right power and energy

with very long shelf life are available

The AECTP200, -6°C issue seems to be no show-stopper

Let’s do it !
