LOCKHEED MARTIN PERFORMS FIRST EVER
OUTDOOR FLIGHT TEST OF
LASER POWERED UAS
PALMDALE,
Calif., August 7, 2012 -- Lockheed Martin [NYSE: LMT] and LaserMotive, Inc., have completed a series of flight
tests of the Stalker
Unmanned Aerial System (UAS) to further validate the performance of an
innovative laser power system. These tests mark the first-ever outdoor flight of
a UAS powered by laser.
Stalker is a
small, silent UAS used by Special Operations Forces since 2006 to perform
intelligence, surveillance and reconnaissance missions. In a recent wind tunnel
test, the UAS demonstrated 48 hours of continuous flight powered by this innovative laser
system.
“This series
of proof-of-concept tests took place in a remote desert location where
environmental factors like wind and heat were constants. Not only did we
demonstrate that the laser powered Stalker could perform well in this type of
environment, we flew during both day and night without incident,” said Tom Koonce, Lockheed Martin
Skunk Works® Stalker program manager. “Ultimately we hope to provide
our customers with remarkably long endurance to extend and expand the mission
profiles possible for a small UAS like Stalker.”
For the
demonstration, the Stalker was fitted with a lightweight photovoltaic receiver
and on-board power management hardware. The ground-based laser transmitter was
based on LaserMotive’s hardware developed for its winning entry in the 2009 NASA
Centennial Challenge. Accomplishments of these
proof-of-concept flights include:
·
Demonstrated net positive power to
Stalker in flight, at ranges up to 600 meters.
·
Proved
that the laser did not damage the Stalker and that the addition of the laser
receiver did not impact its normal flight operations or
aerodynamics.
·
Operated
multiple test flights in a range of desert conditions (day and night, high
temperatures, and strong winds), demonstrating the ruggedness of the
Stalker-mounted laser receiver power system.
·
The beam
director tracked the receiver for long periods, with centimeter accuracy at 500
meters, despite turbulence and aircraft maneuvers.
·
Met all
operational and safety requirements, including coordination with the Laser
Clearinghouse and flight operations.
“We’re
excited to work with Lockheed Martin to validate the ability of lasers to power
Stalker in the field,” said Tom Nugent, president of LaserMotive. “Wireless
power via laser is an important emerging technology, and I look forward to
continuing to work together to further prove this technology in future
experiments.”
