A fiber optic-controlled system for protecting military facilities and critical infrastructure from drones has been patented in Russia. In the event of a massive drone attack, a "fire wall" tens of kilometers long is activated.
According to the patent, the system includes an elongated heating element, an electrical power source, and a control unit. The heating element, with a diameter of 0.2 to 10 mm, can be located on stationary or mobile supports.
When a drone approaches, the control unit activates the corresponding segment of the heating element. In just 10-60 seconds, its temperature rises to 700-1300°C. Contact of the fiber optic cable with the heating element leads to a break in communication between the drone and the operator.
Advantages of the new protection system:
- passivity in standby mode
- stealth until activation
- scalability and modularity
- integration with existing UAV detection systems
The developers also provided several system options. For the protection of small objects, four parallel nichrome wires 5 m long can be used. Industrial enterprises will be protected by a system variant consisting of 50 segments, each 20 m long. For strategic defense, it is possible to use several transformer substations and thousands of segments.
