An unmanned aircraft is a type of unmanned aircraft mainly controlled by radio or by its own program. Its successful development and use on the battlefield has opened a new chapter. in "non-contact war" dominated by long-range offensive intelligent weapons and information-based weapons. However, due to the size limitation, drones cannot stay in the sky for a long time to fly. The problem of dynamics has always been an obstacle to be overcome in the application of drones.
Recently demonstrated an innovative laser pointer charging system that can extend the drone's flight time to more than 48 hours, increasing the durability of the flight to 2400%. It is a small silent drone used by the US Special Forces since 2006 to perform intelligence surveillance and reconnaissance tasks.
The indoor flight test was conducted in a wind tunnel. During the test, a modified drone was installed with a dedicated system that enables it to wirelessly transmit energy over long distances, using laser light to provide a continuous power source for the drone. The test results showed that the UAV battery stored more energy after the test than at the beginning of the test, exceeding the endurance goal initially set by the team.
This test is one of the final steps to bring the green laser pointer charging system to the battlefield. By charging while in flight, the system will expand drone capabilities, increase durability, and give the drone a new mission. Our next step is to conduct outdoor drone charging tests. "If the technology can eventually be applied to drones, it will change the status of drone use. It will open a new path for the continued navigation of drones.
The use of laser power for long-distance energy supply is only just beginning, but researchers say it will be used on a wider scale as a ground-based energy supply system. "For example, military vehicles used for latent reconnaissance, or entering frozen places where humans shouldn't stay for long periods of time to observe and experiment. This way the operator only needs to stay in the warm and comfortable room and get all the data he wants.
