Stalker UAV recharges via laser as it flies

Date:20 November 2012 Tags:, , , , , ,

Lockheed Martin’s Skunk Works and LaserMotive, a small start-up near Seattle, are developing a system to power unmanned aerial vehicles (UAV) as they fly. LaserMotive president Tom Nugent says the system is a “wireless extension cord” that saves time and money and lowers risk by enabling electric UAVs to keep flying without landing to recharge or replace their batteries.

The Stalker, a drone favoured by special operations forces, is being used in ground-to-air recharging experiments. During a recent demonstration, engineers conducted a series of flight tests over a desert range in which the system beamed power to a Stalker flying as high as 600 metres. The system’s laser-beam director tracked the drone’s receiver “with centimetre accuracy despite turbulence and aircraft manoeuvres”, according to Lockheed officials.
