Ruggedization of Electronics for
Deployed Military Environments
S
ome environmental constraints
for deployed military computing
systems are operational temperature,
humidity, sand, dust,
vibration, shock/basic, leakage (immersion),
steam and water jet cleaning, rapid
decompression, contamination by fluids
(e.g. oil, fuel, cleaning), nuclear hardness,
and input voltage. In addition, the type of
platform or vehicle on which the electronics
are to be placed will have its own
typical operating environments and related
ruggedization requirements. For example,
tracked combat vehicles, such as
tanks, will have quite different requirements
compared to wheeled tactical vehicles,
so immersion, while not typically a
requirement for tactical vehicles, but will
be a requirement for tactical combat vehicles
because they will need to be able
to ford through water.
The ruggedization requirements
for different environments
are well defined.
For example,
ground combat vehicle environments
are covered by the US Army CCDC
GVSC Automotive Tank Purchase Description:
Interface Standard - Environmental
Conditions for the Heavy Brigade
Combat Team Tracked Vehicle Standard
(ATPD-2404 21-OCT-2011) and newer revisions.
This relatively straightforward
and short document pulls together a
number of standards (e.g. MIL-STD-810)
by reference to provide operational environment
constraints that must be considered
for any materiel solutions intended
for use within ground combat
platforms. In short, any equipment
within such a platform will suffer wide
temperature ranges, high shock, lots of
vibration, and a dirty environment,
among the many other environmental
conditions rarely if ever considered for
commercial electronic systems - most
specifically computing systems - that
were originally designed for operation in
commercial benign environments (e.g.
home, office, server room, data center).
Today, system integrators have a
wide range of commercial-off-the-shelf
(COTS) electronics solutions from which
to consider when designing their deployed
electronics solutions for military
vehicles. COTS electronics offered in the
marketplace can range from
pure commercial products,
such as those
