Lockheed Martin to Design Nano Air
Vehicle to Monitor the Urban Battlefield
The Defense Advanced Research Projects
Agency (DARPA) awarded Lockheed Martin a $1.7-million,
10-month contract to design a revolutionary remote-controlled
nano air vehicle (NAV) that will collect military intelligence
indoors and outdoors on the urban battlefield.
Lockheed Martin Advanced Technology Laboratories (ATL)
leads a team that will design a remote-controlled NAV,
similar in size and shape to a maple tree seed. A chemical
rocket enclosed in its one-bladed wing will power a
sensor payload module more than 1,100 yards. Delivered
from a hover and weighing up to 0.07 ounces, the module
will be interchangeable based on mission requirements.
Besides controlling lift and pitch, the wing will also
house telemetry, communications, navigation, imaging
sensors, and battery power. The NAV will be about 1.5
inches long and have a maximum takeoff weight of about
0.35 ounces.
In typical operation, a warfighter will launch the NAV
and fly it toward the target by viewing its flight path
through a camera embedded in the wing. Like a maple
tree seed, the one-bladed device will rotate in flight,
but its camera will provide a stable forward view and
transmit images back to a small, hand-held display.
As the system matures, a simple autopilot aboard the
NAV will provide limited autonomous operations. Once
the NAV delivers its payload, it will return to the
warfighter for collection and refurbishment.
According to James Marsh, ATL director, designing and
building such a small device will require revolutionary
manufacturing technologies to integrate near-microscopic
components into the airframe. But even the airframe
will require a challenging combination of new and emerging
technologies.
"The challenges are both exciting and daunting,
because some of the technologies vital to our success
have yet to be discovered," Marsh said. "We
know going in that we need some of the best minds in
manufacturing technology and in the development and
integration of highly sophisticated, software- driven
control technologies and mission systems."
The contract will fund conceptual design and risk reduction
using prototypes of the engine, airframe, flight control
system, and communications system as well as computer
models of the guidance system and sensors. Following
a successful preliminary design review planned for summer
2007 and a sequence of go/no-go tests, DARPA may fund
an additional 18-month period during which Lockheed
Martin will design and test a flying prototype.
Lockheed Martin ATL leads a team that includes Lockheed
Martin Advanced Development Programs (Skunk Works),
Lockheed Martin Advanced Technology Center, the Lockheed
Martin-managed Sandia National Laboratories, AeroCraft,
ATK Thiokol and the University of Pennsylvania.
Lockheed Martin's NAV program is part of a DARPA effort
from its Defense Sciences Office to improve the quality,
quantity, and reliability of information gathered and
transmitted by unattended ground sensors. The effectiveness
of these sensors may be dependent on their precise location.
Achieving optimal monitoring and communication often
requires precise deployment of sensors.
