In China, UAVs with a closed wing are being tested.

The PLA will soon receive several intelligence drones Xianglong with a range of up to 7 thousand km, reports MIC with reference to Defense Aerospace.

The device, equipped with a closed wing, is currently being tested.

“A closed, or annular, wing actually consists of two wings located one above the other and connected to each other by curved ends. In the frontal projection such a wing resembles a ring. A closed wing has the smallest inductive resistance, since end vortex flows are practically not formed at its ending, ”the publication says.

It is noted that the annular wing also has a large lifting force and allows the device to “fly at low speed without using flaps”.

At the same time, “a closed wing is quite sensitive to stalling — if at high angles of attack the smooth flow around the upper surface is disturbed, then the wing loses its lifting force and the aircraft controllability,” the resource writes.

According to the author, the Chinese designers chose such a wing structure due to the fact that “due to its aerodynamic characteristics, it allows to reduce fuel consumption in flight and increase the range”.

According to the report, the drone can rise to an altitude of 18 km and reach speeds of up to 750 km / h. The range of the device, according to unconfirmed data, reaches 7-th thousand km.

[Trevis]

A considerable apparatus.

[vkl.47]

Well, the range with the height is also not small

[Alex_Rarog]

Damn, but it turns out solidly if you still teach him how to refuel, then almost a drone strategist will come out! Rempekt however! Something of their own and with such characteristics !!!

[KasDS]

Something is not particularly closed ...

[dauria]

Something is not particularly closed ...

In-in ... I also saw only an oblique low-wing. True brace (upper piece) is made well streamlined. Perhaps he even creates part of the lifting force. But in my opinion, everything was done for the sake of simplifying the design (the main wing can be made less durable, part of the bending and torsion loads will take on the brace). And from inductive there are ridges at the tips.

"flight duration up to 7 thousand km"

Still range.

[twincam]

ahahaa)))
if duration = 7 tkm, then range = 8 hours)))

And the mass of the UAV is 5 meters.

It depends on how fast it will fly. If 500 km / h, like the Yak-40, then 14 hours.))

Copied ...

[maxim947]

Who is stopping us from copying? conscience ???, I don’t think ...

[Alex koch]

Why copy? Is there no development of your own? Won Antonovskiy product 181 at least

And from whom did they copy this UAV, if not secret?

[krops777]

Dumb copying will not lead to anything good, and they will be in the role of catching up, we need to develop our school of aircraft manufacturing, although we are certainly better.

[serverny]

That's why the Russian Federation develops its unique school of aircraft engineering at an accelerated pace! (Oh wait ... instead of purchasing licenses in Israel ...)
Yes, and long-range reconnaissance drones are just around the corner - in just 5-7 years, they will release analogues of what the Chinese are flying now.
And there is another 10 years - and we will see the first shock drone with a proud VKS banner!

PS Well, okay, it’s useless to whine about the fact that polymers are drunk in drones. The fact that this arms market for the Russian Federation with its lag of 10-15 years is lost, notarized and recorded.

The same thing, after the Suvorov military school, a local spill, he dreamed of entering the Balashov VVAUL, but the school was disbanded, and from Kazakhstan there were few places to study in the Russian Federation with an aviation bias. I went PV, served 90 years, my older brother called for me, graduate RVSN. Then I had to get a second education at the Polytechnic.

There is such a thing, but there are strange freaks who fly, the guys work with me as aircraft modellers, not some prize-winners of the USSR, such models are already showing strange.

An interesting device, well done Chinese, and you better deal with glasses - from each according to his abilities!

Sorry, dear Bayonet. It’s not for you to discuss my abilities, and especially not for you to talk about what I could do and have done for my country. And the glasses ... Well, maybe some mabutu has four glasses and is knocked down. A normal guy - only the flight of creativity opens .... Not a damn thing, you didn't understand anything of what I wrote. And if so, then do not fig stupid comments insert "just to check in" ...

And the topic is understandable, as in the photo above, I saw it in the application for MK from paper.

His Iraqis back in 2015 purchased, to be exact, his predecessor under the name CH-4B, also in the shock version.


It is not clear why we will not buy? Although it may have long been bought in single copies for study, they simply do not advertise.

Well there was a desire for a traitor reconnaissance version. and I’ve sold it, I have forbidden to see the congress. With black, but the Hercules and the turboprop attack aircraft without problems, ours refused.

It’s unlikely that you can offer much to China, but what you yourself know, without program management, I think that it couldn’t do without friends from the Middle East, they have their own gesheft and the Chinese will not be very hard to advertise. Yes, and you still have a hypertrophied sense of self dignity. In the Government they suddenly find out.

We love to go outside, plus a large private sector. Almaty is a large village with its pros and cons. Roads are all downhill. There are up and down, do not get lost.
Jeeps are a necessity. In winter, snow falls per meter. And there are frosts down to -27. So SOUTH. Spring it all melts ....

Thanks to Serdyukov, even the ancient Israeli drones bought, or even that would not have happened ... but apparently it will not, even if there are some developments until they are tested until the series comes out ... it will become obsolete ...

received it or not, I don’t know, but thanks to this deal we have the "newest" UAVs Forpost)) And others are not expected, and even if something is being developed, thanks to our tyagomotina by the time of serial production they will also be the same "newest" ...

[demiurg]

Who will be scouted by this futuristic unit? I have no doubt that any decent state has air defense, which with joy and fireworks will remove this beauty from the sky.
