Chinese Navy underwater drone allegedly caught by Indonesian fisherman

55

An unusual item was caught in the territorial waters of Indonesia on December 20. An Indonesian fisherman's catch was allegedly an underwater drone of the Chinese People's Liberation Army.


Judging by the photographs, the find strongly resembles the Sea Wing unmanned underwater vehicle belonging to the Chinese military.

The discovery of the drone became known thanks to the publication of the Indonesian edition detikNews. It says that the drone, on the nose of which is located something like a sensor grid, reaches a length of just over two meters, not counting the long antenna (about 93 cm) or the sensor coming from the back. The drone has a torpedo-shaped body with a pair of wings (50 cm each) installed in the center, and a vertical tail.


The drone was caught near the Selayar Islands in the South Sulawesi province. This zone is located at a considerable distance from the territorial waters of the PRC. It is located between the Sunda and Lombok Straits, which connect the Indian Ocean with the South China Sea.


The fact that Chinese underwater drones are present here may indicate that the PRC is studying the underwater relief outside its territorial waters. If the drones belong to the PLA, then this could mean that China is studying routes of passage from the South China Sea to the Indian Ocean for its warships and submarines.

Such glider-type drones are often used for hydrographic surveys and help in the creation of underwater maps. As the PLA Navy works to project its power further and further from the PRC coastline, China needs modern and detailed nautical charts both for its daily tasks and in the event of possible hostilities.

True, China has not officially recognized the loss of a marine drone off the coast of Indonesia

      No, if you look closely, you can see the horizontal rudder, which is located behind and below the body of the "drone".
      I'm interested in something else, but was there a "BUYER" FOR THIS "GOLDEN FISH"? If yes, then their capture by fishermen may become industrial basis. laughing

              Sorry, not in the know about the losharik story. You want to say that the "enemies" mined some object almost in line of sight from our coast and the apparatus was blown up during its examination? This threatens with reciprocal surprises for the "partners". This is why no one ever does that. And for these cases, the corresponding international agreements are signed. Imagine a situation when fishermen caught something with a bottom trawl, lifted it, and on board this thing jerked and killed someone. An international scandal with all the ensuing consequences and claims.

Waking up, Vladimir Vasilyevich immediately remembered these “horns” - detonators.

        And is it so?
        It may well speak about the fact of low-quality production and curved design.
        The currents swept away the broken apparatus ...

      He mainly uses the force of the current
      The marine glider Petrel II features a hybrid propulsion system that allows you to plan along a saw-tooth path using underwater currents, or to perform horizontal movement using an electric jet engine.
      According to the company, the Sea Wing family currently includes the youngest model Sea Wing 300 weighing 60 kg, length 1,9 meters, working depth 300 meters and radius 1000 km. Moving at planning speeds up to an 1 node, the Sea Wing 300 glider can operate independently for up to 40 days.
      Sea Wing 1000-I and Sea Wing 1000-II weighing 65 kg and 70 kg, length 2,1 m and 2,3 m, respectively, are able to reach operational depth 1000 meters at the same speeds, although the latter model is designed to perform advanced tasks and therefore has the maximum declared range sailing 1500 km and can operate continuously up to 60 days.

      No. This is an underwater glider - an apparatus that is set in motion by changing the buoyancy. So, with negative buoyancy, when submerging, it moves in an aquatic environment like a glider in the atmosphere. And when surfacing, the "wings" change the angle of attack and the result is a "reverse glider". This bullshit moves on sawtooth trajectory.

        The wings of these gliders are motionless. There, synchronously with the change in buoyancy, the change in trim is worked out. When surfacing, the feed becomes heavier, and when diving, the bow part. This provides the possibility of undulating (up - down) forward movement with a horizontal speed of about 0,27 m / s.

              Perhaps, on the contrary, the stator, it is much more compact in length and the center of gravity is easier to shift, and the heavy anchor is not needed.
              The magnets are on the base, and he drives past them.
              The stator magnetic system is heavy, copper and iron are solid, if necessary, it can be additionally weighted.
              But maybe a classic ordinary screw-nut with a low-sided engine.
              An interesting solution with a glider.
              On the other hand, after all, it must change the buoyancy, so a simple shift of the load will not work, there must be some kind of capacity, or vice versa, something airy.
              And then it makes no sense to put two different devices, if you can change the trim and buoyancy with one trim

                All this has to do with the almost unrecognized science of bionics. By the way, your assumption about a screw with a nut for moving ballast could be quite logically combined with the contraction of the glider's "swim bladder" when moving the load towards the bow and, accordingly, its expansion when the weight moves back to the stern, thus combining the two the main functions of the propeller (change of trim and buoyancy), so to speak, in one "bottle", naturally synchronizing them by means of elementary mechanics. smile It is only necessary to create a low-noise mechanical scheme of this bionic miracle to ensure its own safety.

                  The siphon can be compressed in the same way with a linear motor, there will be even less noise. I would put it in front, when the load moves forward, the buoyancy decreases at the same time, the siphon is compressed and a trim on the nose is formed. Perhaps that is why the wings are shifted backward - to the front of the air siphon, which shifts the center of gravity back.
                  If we move the load backward, the volume of the siphon increases and the buoyancy increases, at the same time we get a trim on the stern — the glider moves to a shallower depth, while moving forward.

                    This is exactly what I meant, but without the bellows, but with the cylinder and the piston. Only now, will the linear-electric motor and, as a consequence, the gearless drive provide the required compression force? A small change in volume is not enough.
