WASHINGTON (Army News Service) -- The technology
behind space ship lasers and force fields is a lot closer to reality than many
think.
Although those lasers and force fields won't be
fielded for a few more years, Gus Khalil, an engineer at the Army's Tank and
Automotive Command in Dearborn, Mich., said the Army has identified what they
want for the Army's Future Combat System.
"There's a lot more demands for the FCS vehicle than
there are for the legacy force today," he said. "Anything we do today that gives
the soldiers less capability than he has is unacceptable."
That technology is being developed for the Army's
Future Combat System, the family of 16 manned, unmanned, ground and aerial
vehicles the Army wants fielded by 2010.
The manned ground vehicles have to weigh less than 20
tones. They also have to be as fast, as mobile and as lethal as an M-1A2 Abrams
and M2 Bradley fighting vehicle.
Doing all that will be like making a Toyota truck as
durable as an 18-wheel semi-truck, one TARDECE engineer quipped at a recent FCS
conference in Dearborn, Mich.
But it is doable Khalil said. To demonstrate that,
Khalil had a mock-up of the laser gun system at the Association of the U.S. Army
annual meeting in Washington, D.C., Oct. 6-8.
The gun program falls under the Combat Hybrid Power
System. Initiated by DARPA six years ago and handed over to TARDEC two years
ago, the program is developing the FCS' "pulsed power" weapons.
Since the system is just being developed, the weapons
could be Electro-thermal Chemical guns or even a laser gun capable of firing
artillery rounds or destroying tanks, he said.
The mock up showed how TARDEC wants the system to
work. On one end was a pack of three lithium-ion battery modules. When it was
"fired" it went through a converter that increased the charge from 100 volts to
1,000 volts.
From there it goes to the pulse-forming network, a
nest of capacitors and inductors, where the now 1,000 volts will be turned into
a "pulse discharge" that will last less than one-millionth of a second, he said.
From there the pulse of electricity goes through an
out-put switch that will fire the pulse to its intended target, Khalil
said.
The pulse was demonstrated through a bank of four
strobe lights. If someone wasn't careful the lights could burn holes in their
retinas, he said.
Khalil said tests have shown that 600-volts to
10,000-volts weapons are possible. And that's what they're forecasting to be in
the FCS, Khalil said.
The modules' life span depends on how they're used,
he said. If they're used just for mobility they can potentially last years,
about 15, he said. If they use chemical or laser guns, they won't last long, he
said.
"I don't know the exact number because we have not
done that yet," Khalil said of how many times the batteries will fire the
weapons.
He wants the batteries to last 50 rounds or "firings"
but the modules will last only 20 rounds right now, he said.
The FCS is projected to have anywhere from 20-50 of
those battery modules and since battery technology is getting smaller, that
requirement will be met, Khalil said.
The pulse gun will also have the ability to fire
something like today's sabot anti-tank round. But the FCS pulse weapon will give
it more penetration capability than it already has, Khalil said.
To the soldier on the battlefield, it will look
similar to a sabot round -- a flash of light -- and the result might be the same
-- a destroyed tank or armored vehicle, he said.
But Khalil's team isn't stopping there. His team is
also developing electro-magnetic armor capable of stopping not only other pulsed
weapons but conventional weapons.
The electro-magnetic armor will also be run from the
same power source that will power the weapons system and the engine.
If the power system that powers the pulse gun that
Khalil is designing fires in milli-seconds, that same source will power the
electric armor in micro-seconds, he said. In other words, it's much faster and
uses a lot more juice, he explained.
The biggest challenge for his team is to run the gun
and armor off the same batteries that will run the engine, Khalil
said.
