Laser Technology Provides 'permanent' Battery Life For Drones
Aug 09, 2018

According to foreign media reports, in January 2019, Silent Falcon's solar drone will use the SUPER PBD system of the US Department of Defense Advanced Research Projects Agency for remote laser charging testing.

The Silent Falcon solar drone has a wingspan of 14 feet, a length of 7 feet and weighs about 35 pounds and can carry a payload of 3 kilograms. The aircraft's roof is about 20,000 feet long, but in military surveillance missions, the roof is typically between 1,600 feet and 5,000 feet. The wing is fitted with a solar panel that provides an additional five hours of battery life for the drone in operation.

The SUPER PBD system transmits laser light from a ground base station or airborne (referred to as a conventional aircraft carrying a laser launcher) to a solar panel on the tail of the drone to convert light energy into electrical energy.

Silent Falcon Chairman Brown said that if laser power is used, there is theoretically no limit on the life of the drone. “The safety issue of launching the laser into the air is the primary consideration in this test. But for safety reasons, the laser from this test will be launched from a base station on the ridge, and the distance from the drone is 10 thousand. On the other hand, due to the influence of clouds, smoke, rain, etc. in the laser emission path, the ability of the drone to receive laser energy will also decrease."

Brown firmly believes that this technology can be applied to a range of more than 10 kilometers in the future, and can also be used to power manned aircraft.
