Successful 48+ Hour Laser-Powered UAS Demonstration

Written by on Wednesday, July 11th, 2012

We are proud to announce that Lockheed Martin issued a press release today about a joint test with LaserMotive using laser power to keep their Stalker UAS powered for more than 48 hours. We’ll post more details soon! Here’s the text of the release:

PALMDALE, Calif., July 9, 2012 — Lockheed Martin [NYSE: LMT] and LaserMotive, Inc., recently demonstrated the capabilities of an innovative laser power system to extend the Stalker Unmanned Aerial System (UAS) flight time to more than 48 hours. This increase in flight duration represents an improvement of 2,400 percent.

Stalker is a small, silent UAS used by Special Operations Forces since 2006 to perform intelligence, surveillance and reconnaissance missions.

“We’re pleased with the results of this test. Laser power holds real promise in extending the capabilities of Stalker,” said Tom Koonce, Lockheed Martin Skunk Works® Stalker program manager. “A ground-to-air recharging system like this allows us to provide practically unlimited flight endurance to extend and expand the mission profiles that the Stalker vehicle can fulfill.”

The Stalker UAS was modified for the indoor flight test to incorporate LaserMotive’s proprietary system that makes it possible to wirelessly transfer energy over long distances using laser light to create a continual source of power to the UAS. At the conclusion of the flight test, held in a wind tunnel, the battery on the Stalker UAS had more energy stored than it did at the beginning of the test. The test was concluded only because the flight had already surpassed the initial endurance goals set by the team.

“This test is one of the final steps in bringing laser-powered flight to the field,” said Tom Nugent, president of LaserMotive. “By enabling in-flight recharging, this system will ultimately extend capabilities, improve endurance and enable new missions for electric aircraft. The next step in proving the reality of this technology is to demonstrate it outdoors in an extended flight of the Stalker.”

Headquartered in Kent, Wash., LaserMotive is a privately-held research and development company specializing in laser power beaming for commercial applications.

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 123,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s net sales for 2011 were $46.5 billion.

  1. […] the unmanned aircraft is in flight. So far the Lockheed Martin/LaserMotive team has been able to keep a Lockheed Martin Skunkworks Stalker "Unmanned Aerial System (UAS)"/drone aloft in a … via this wireless power-beaming battery-recharging tech, thus achieving a 2400-percent […]

  2. […] called LaserMotive to “refuel” electric aircraft in flight using laser beams that charge batteries wirelessly, and the latest round of testing not only met but beat expectations. The test took place indoors […]

  3. […] This outdoor test was the next phase in a planned set of tests, following on the recent successful 48-hour wind tunnel test. Here’s the text of the release: PALMDALE, Calif., August 7, 2012 — Lockheed Martin (LMT) […]

    I presume if this technology can be scaled up we could be flying around in commercial aircraft in a few years time? You could have a series of ground stations providing power over flight routes, and eventually from satalites to fly over oceans. The whole aircraft industry could become kerosene free.

    But what’s the catch, does this technology work in all weather, snow, hail, rain, fog, etc.

    Is it capable of scaling and enable commercial type planes with high payloads, will it produce enough power to keep large commercial planes aloft?

    Its interesting technology and I can see it has a future.
