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

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


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


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.

        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 !!!

      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.

    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.

      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. smile

      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.
