Chinese laser system eliminates small UAVs within minutes

Only three countries used armed drones in battle, despite the fact that a number of world powers and non-state actors have UAVs. Pictured: Israeli soldier launches a drone outside the Gaza Strip on July 22, 2014, July, Reuters / Amir Cohen

Chinese state-owned media have reported that the Chinese military have deployed a high-precision laser defense system capable of shooting down small unmanned aerial vehicles flying at low altitude. As expected, the technology will be used to eliminate the threat of unidentified drones flying over urban areas that may be involved by terrorists or simply for illegal intelligence activities.

According to reports, the laser defense system has some similarities with the Israeli Iron Dome, and is capable of destroying drones and other small aircraft within an 1,2 radius of a mile within five seconds from the moment they were detected, reports Xinhua news agency.

The report quotes a statement from the Chinese Academy of Engineering Physics (CAEP). One of the developers of the system said that the laser system "will play a key role in ensuring security during major events in urban areas."

The development of the system seems to be taking place against the background of growing concern about the “vile” use of unmanned aerial vehicles. The unmanned aerial vehicle is inexpensive, it is easier to use than most modern weapons. And thus causes concern that terrorists will be able to use drones against the crowd or buildings.

"Intercepting such UAVs is usually a job for snipers and helicopters, but their probability of success is not so high, and errors with accuracy can lead to undesirable damage," Yi Jinsong, manager of CAEP, told Xinhua news agency. The Chinese state news agency also published photographs of the wreckage of small drones that they claimed were shot down by the system, reports France-Presse.

Antiinflammatory laser system can be stationary or deployed on vehicles. As a result of tests, she demonstrated 100-percent performance against drone 30, reports Xinhua.

        I believe they are heating, the drone loses its shape and tumbles to the ground, if blinded, it will not hurt to continue the flight, the altimeter, gyroscope, GPS will not suffer from this

        Even as it turns out. Do not increase the power of one
        beam, and increase the number of rays focused
        at one point.
        There can be thousands of rays in one laser. And they burn at a given distance
        target at one point.

          Quite right. Even in the mathematical "problem of the pharaohs" the principles of algorithmic construction of calculations of such rays and the calculation of their "beams" of intersection for the formation of the longitudinal pulse frequency are noted. Moreover, the rays themselves, as energy flows, can be "twisted" to increase their energy "power".

    If someone has nothing to do, then you can heat it up. The simplest solution is to disable optics and electronics. And you need less power and a better result.

      The length of the UAV is about 100 mm, the rotor diameter is 120 mm. Its total weight is 16 grams (the manufacturer claims 18), including 3 security cameras. The entire set, excluding the display, weighs less than 1 kg (the manufacturer claims 1,3 kg).

      An autopilot installed on board the Black Hornet allows the operator to control the drone in two modes. The UAV can be controlled either directly by the operator, or act on a route previously laid down in it, remaining on the trajectory thanks to the GPS signal receiver installed on it. The digital data line allows the operator to control the UAV in the line of sight within 1000 m (manufacturer claims 1500 m).

      It’s your truth, to detect an air target, in this case a drone, is no less important than to shoot it down. You can detect with cameras with video analytics and all sorts of backlights, thermal imagers or radar (multifunctional radar detection and guidance) most likely in the millimeter range. In the latter case, one does not have to talk about cheapness. How the Chinese discovered the targets and aimed them at the laser, in other words about the composition of the system, the CAEP manager Yi Jinsong, showing oriental modesty, kept silent. Also, the wreckage of the drones was shown, but not a video of how they were formed from flying targets. All this testifies to the fact that the creation of means to combat pespilots is on the agenda. And developers in different countries are closely engaged in this problem. We will soon find out and see a specific video, rather than written in black hieroglyphs on white rice paper.

    The laser defense system reportedly shares some resemblance to the Israeli Iron Dome,


    I mean, after all, probably "Iron Beam", and not "Iron Dome".

    By the way, probably half a year ago there was an article here that the US Navy is testing a laser capable of shooting down small UAVs.
    There was a video even:

      A laser beam is an energy stream. So it can be transformed and put back and on the same beam, which he comes. But there will be misfortune. You attack yourself.

      The laser beam is not a sun bunny. The first problem is the limitation of hatchability over the width of the spectrum and long waves.
      The second problem is energy dissipation and heat dissipation. (The mirror is heated well by the sun.
      A high-energy laser perfectly burns the reflective coating of the mirror behind the glass.)

        In the laser installation itself, a beam is also formed using a system of mirrors and prisms. The coating of optical elements simply has to match the laser wavelength.

        Naturally, no one will make "mirror UAVs". It is expensive and impractical.

        The schoolboy here calculated that having certain parametric properties of the laser beam, it is possible to calculate the break-in moment formed on the longitudinal vector of the directed flow from the source (this is not counting the flow spin). Then even an insignificant impulse intensifying this break-in moment will cause a reverse flow. I can’t say how he will act on the source of this. But what the impact will be is undoubtedly.
        You see, but the fact is that the flight of a high-speed aircraft, for example, can be justified not only by the parametric properties of the engine and the physical phenomenon causing the reactive force vector, but also by the fact that it is possible to level the resistance of any physical medium in the front end, and theoretically create a priority factor, which will control the flow not creating movement, but "falling" into space along the necessary vector.
        And I’ll say that in practice it’s not so difficult. It’s hard to perceive all this. This is yes!

          Why is it difficult to perceive?
          Mathematically, the creation of a generator of space warping, to overcome the speed limit of light, is also quite "not difficult" ... on paper.
          (But applied research promises only results on conceptual feasibility, years through 30. And then another half a century or a century to develop technologies and solutions for energy supply)

          By the time it is possible to implement such protection "in metal", it will most likely be no longer relevant. (Unlike hyperdrive laughing )

            You are right only in the aspect that, on a modern elemental basis, the construction of induction devices. concentration and transmission of email. current it is impossible to do. And this applies not only to electrical devices, this also applies to devices for converting hydro-gas-dynamic flows. The fact is that no one calculates these devices within the limits of their potential energy capabilities. The same screw or turbine is not considered within their non-destructive mode of operation. For example, induction coils of all kinds. They all have not only density limits of transformed magnetic fluxes, but also algorithms that determine their destruction limits at a certain level.
            Therefore, simple constructive solutions allow cardinally quick and effective implementation of this conceptual feasibility. Actually, all this is nonsense and nonsense on my part. I don’t understand what makes me write all this.
