The “Onset”
In our 2011 presentation …
D&EP\Presentations\Fuze\NDIA 60 Fuze Conf\60th Annual Fuze Conference_The Power of the Fuze, May 2017
we have analysed the requirements …
… and proposed a small Fuze battery
Copyright Diehl & Eagle Picher GmbH5 Copyright Diehl & Eagle Picher GmbH
The Start
Naively we thought …
substitute a 5 – 10 mJ set-back-generator
with a 100 mJ fuze battery
¼ the size of the generator
is not a big issue
we used to build Artillery/Mortar-Fuze Batteries
with 10,000 times more Capacity
just reduce the diameter by a factor of 3
and
the height by factor of 2.5

Customers Challenge
Our 2014 presentation …
D&EP\Presentations\Fuze\NDIA 60 Fuze Conf\60th Annual Fuze Conference_The Power of the Fuze, May 2017
supplemented by DoD 2014.1 SBIR
rise time < 10/100 ms
current > 2/40 mA
voltage > 2.9 V

Energy hundred´s of mJ
Power most of the Energy within ms
some W´s
Current hundred´s of mA
Rise time almost instantaneously
tr = close to zero
Life time up to 60 s
Environment spinning and none spinning

avoid (delay) high current until battery
is sufficiently activated(electrolyte has reached the place where it is supposed to be)
high capacitive load can be even worse
(remember: empty capacitor is a “short circuit”)

Conclusion
Lithium Reserve Batteries provide very short Activation Time
under high forces
Acceleration
Spin
if properly designed
under proper load management
