Chinese Navy underwater drone allegedly caught by Indonesian fisherman

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.

Detection drone became known thanks to the publication of the Indonesian edition of detikNews. It says that the drone, which has something like a sensor array on its nose, reaches a length of just over two meters, not counting the long antenna (about 93 cm) or a sensor coming from the back. The drone has a torpedo-shaped body with a pair of wings (50 cm each) mounted 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 submarines are present here drones may indicate that the PRC is engaged in the study of underwater terrain outside its territorial waters. If the drones belong to the PLA, this could mean that China is exploring routes 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.

[donavi49]

Well, here's the question. This CWing is massive, and it is made scientifically. And they offer for export.

Well, even in the photo they are a little different ... There is also more interesting that he carries in his memory blocks.

Well, it's on the fick, such a "catch". And if it were shandarahnulo?

This is just a flaw of the creators of the drone. No one is insured against loss, therefore, a special charge must be provided so that it just shoots when it gets into someone else's curious little hands.

[Podvodnik]

so that it just shoots when it hits strangers

This is prohibited by international treaties. No autopsy self-destructors.

Self-flooding after battery exhaustion. Otherwise, a lawsuit in court for damage to curious fishermen.

Right. Serious people choose serious, proven solutions. And this drone was not taken very seriously.

[Podvodnik]

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.

[evgen1221]

What a scandal, everything is solved quietly by phone or, in extreme cases, by the departure of the director of the CIA or SVR at the place of emergency.

[Kerensky]

a special charge must be provided

Also provided for by German designers. "On the Bull Field ..." well, you will find further ...

Hydrostatic device. This is a hatch with a tube in the center. Triggers to detonate when removed from water.

I remember Pikul's "Three ages of Okini-san" :

On September 6, Kokovtsev spent the night on the "Rurik", summoned to Revel on business: on Dago, naive fishermen began to pick up "iron barrels with horns" thrown by the surf, which they did not understand (mines!). Waking up, Vladimir Vasilyevich immediately remembered these “horns” - detonators.
- Galvanic impact type! He said to Kolchak over tea in the Rurik's wardroom. - God forbid, if the Estonians decide to bite these horns with an ax, wanting to see what is inside, if the kerosene needed in the household will flow?

[Real Pilot]

The fact of the presence of Chinese underwater drones here may indicate that the PRC is studying the underwater relief outside its territorial waters.

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 ...

Remember: an ax floats down the river from the city of Kukuev ... Why do we need it, a rusty piece of iron!

PS: maybe they are exploring! In each of us, a New Year's conspiracy theorist is sitting at the table

Happy Holiday! Hooray! Hooray! Hooray!

Already wrote - there is NO engine! This is an underwater glider. More information about the Sea Wing family was on the same site: https://topwar.ru/151264-avtonomnye-morskie-sistemy-na-strazhe-interesov-kitaja.html

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.
Sorry! I explained how I managed ...

[Errr]

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.

[Avior]

Most likely, there the load moves forward and backward, changes the center of gravity and with it, trim

[Errr]

Most likely a long weighty rod of the type of an armature of a linear electric motor.

[Avior]

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

[Errr]

Interesting.
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. It is only necessary to create a low-noise mechanical scheme of this bionic miracle to ensure its own safety.

[Avior]

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.

[Errr]

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.

Damn the sea! I didn't even think about such a possibility !!! Bravo!

Fill the main ballast tanks! We go at periscope depth.
Happy you!

Not the first time they lose ... by accident or on purpose? )

[Thrifty]

Actually, the wings are not in the very center of the hull, but are shifted towards the rear of the hull ..

It is logical to place the wings in the center of mass, but it is not necessarily in the middle

Very far away ... They have ambitions on a global scale and for a very long time. According to Asian canons, they act quietly and efficiently and buy anything and everything.

[Sidor Amenpodestovich]

A question for connoisseurs.
If a drone is a remotely controlled device, then is it correct to call an underwater unmanned vehicle a drone, unless, of course, it is controlled by wire?

[Avior]

Can theoretically be controlled by ultrasound
You cannot convey a picture like that, and control commands are easy, especially since there will not be very many commands
Again, ultrasound can track its position according to the principle of secondary radar and

In this case, is it possible to call corrected artillery shells drones?

[Avior]

Drone is the colloquial name for a UAV.
The UAV can be controlled remotely, it can be automatically, or it can be a combination of these methods.
And as for the projectile, I'm not sure that the term aircraft can be applied to it at all.

[Sidor Amenpodestovich]

So it is incorrect to call a drone any other unmanned vehicle other than an aircraft.

Is that an underwater drone

[Narak-zempo]

A flaw: it is necessary to equip drones with subversive charges to protect themselves from such would-be fishermen.

[Flashpoint]

And what will give the charge? Structural deformation and debris, often objectively with preserved aggregate integrity for later analysis. This is not a torpedo, the warhead torpedo has a big one. Design a drone with a multi-charge plug? And what should then be the principle of self-liquidation?
Again, the class of work with such a drone will be completely different ...

At the very least, he will tear his hands off. This is also a good thing. They won't climb next time.

The era of drones wandering "by themselves" is not soon, but everything is heading for that.

Let him announce a tender for the purchase of this device, there will be buyers and the person will earn a lot.

The world makes 96 million cars a year.
Of these, China is more than 30 million and they drive
all over the ball. And now along the bottom
seas and oceans millions of drones will drive.
Grandfather told me - Soviet tanks in the 45th
in China - the column goes with a minimum interval,
there is a cloud of dust behind each car. Soldier on armor
dropped an aluminum mug - Chinese head over heels
rolls right next to the tracks and triumphantly
raises a crumpled mug. The next day he already
sells on the market in perfect shape, covered with enamel,
and on it the chicken is drawn as if it were alive and
will run away now.
