"Captain Xue, what did you say just now? Can yun-18nb carry a T-72 main battle tank in full combat weight
Before Xue Weidong finished speaking, the cadre from the heavy armed forces almost jumped up from the spot like a cat with its tail on.
The news is amazing.
What is the combat full weight state? Generally speaking, weapons and equipment are full of oil, ammunition and personnel.
In other words, if you pull it out, you can go directly to the battlefield.
To be able to carry a main battle tank in full combat status is not as simple as extraordinary, but really huge.
Because this means that the rapid response capability of the army, especially the heavy armored forces, has been improved exponentially.
In the past, it took three to five days to deliver a heavy armored battalion to a designated area more than 1000 kilometers away. Now it may take less than 48 hours to quickly complete the deployment.
There's no way. Who can let the air transport platform that can carry the main battle tanks in the full combat state transport almost all the army's main battle equipment.
The key problem is that the total combat weight of the T-72 tank is 41 tons, and the maximum transport load of the yun-18nb is only 38 tons. It is barely able to transport a type 88 main combat tank. How can it be increased by more than 3 tons at a time?
There are many people who share the same ideas with the cadres of the heavy armed forces, so that they look at Xue Weidong one after another. In their confused and different eyes, they seem to say, is the maximum load you just said farting or bullshit?
Seeing this, Xue Weidong could not help but smile more strongly, and immediately asked: "is there no redundancy in a good equipment?"
All of them have been soldiers for more than ten years. If you don't understand Xue Weidong's words, take the most common assault rifle as an example. In the hands of some soldiers, it will be used beyond the level and beyond the theoretical data when it was finalized. This is the performance redundancy of equipment.
So when Xue Weidong said these words, the leaders of the heavy armed forces and others could wake up. At the next moment, their faces would turn red as if they were drunk, and they were a little excited.
"So the maximum carrying capacity of yun-18nb is more than 38 tons?" Asked one of the army cadres.
Xue Weidong nodded: "it's the structure that affects the upper load limit of the aircraft. According to the optimization and manufacturing process of Tengfei group, the maximum load limit of the yun-18nb engine room is 55 tons. That is to say, it's OK for the next generation of main battle tanks to be put into the yun-18nb engine room. After all, the structure of the yun-18nb engine, especially the bearing capacity of the bottom plate, is excellent, but for various reasons, There's no way to further improve... "
Xue Weidong seldom opens his mouth, unless he can see things with the right eyes. Obviously, yun-18nb is one of the few things he can see the right way, so he can't stop this saying. He even made a popular science talk about yun-18nb to other army leaders and cadres present.
Can yun-18nb carry the 41 ton T-72 MBT? Of course, but in this way, the voyage of yun-18nb will be reduced to 2200km, because the increased cargo load will be absorbed from the fuel load.
By analogy, loading 55 tons is no problem, but in this state, the voyage of yun-18nb is almost zero, so it doesn't make much sense.
Let alone the maximum structural load of 55 tons, that is, 41 tons, which has a range, is not of great significance.
2200 km is just a simple voyage. The transport plane usually performs a round-trip mission, and can't get fuel supply in the midway. In this case, if the reserved fuel and other emergency measures are removed, the 41 ton yun-18nb can only perform a round-trip voyage of 800 km at most.
800 km, this distance is a bit awkward. High speed trains can arrive in one day. In wartime, this distance is often within the range of the enemy's long-range precision guided weapons.
Therefore, the practical application is not strong.
Therefore, when determining the maximum load of yun-18nb, Tengfei group did not choose the chicken like 41 tons, but the lower 38 tons. The reason is self-evident. The maximum load of 38 tons can reach the effective range of 3740 km. Regardless of various factors, it can make a round trip without supply between 1800 km.
It's 1000 kilometers more than the 800 km round trip carrying 41 tons, at least what a medium-sized transport plane should look like.
In this case, how can Tengfei group set the upper limit of yun-18nb structure load so high? For this reason, a large number of advanced materials and production processes have been applied.
Nothing else, but the 4.5-meter-wide and 17.58-meter-long floor in jiuyun-18nb cargo hold not only uses the latest brand of high-strength aluminum lithium alloy, but also uses the friction stir welding used in the manufacture of the bomb hold of the next generation combat aircraft.
The floor is not installed with a rivet, thus reducing the structural weight and increasing the structural strength several times.There are many similar new processes and technologies, and all of them are integrated together, which has already made yun-18nb exceed the first-class level in the upper limit of structural bearing capacity.
Is it just necessary?
The answer is obvious and, of course, necessary.
The reason is very simple. In addition to meeting the actual needs of the army, the more important role of yun-18nb is to verify the technology of the next generation of 200 ton strategic transport aircraft.
Just like yun-15, some of the technologies are used to verify the feasibility of yun-17, and many of the technologies used in yun-17 are not for the future of yun-18nb?
So generation after generation down, transport technology and key capabilities will be a little bit of exercise out.
This is the so-called trot.
So at the level of yun-18nb, it's natural to aim at the air giant with larger carrying capacity, longer range and more advanced technology.
From this point of view, no matter how much the upper limit of structural bearing capacity of yun-18nb is, it is understandable.
Based on this, we can imagine that in the near future, as long as we enlarge the yun-18nb airframe and solve the problem of fuel carrying capacity, a heavy strategic transport aircraft with a maximum load of 55 tons and a maximum take-off weight of 200 tons will be just around the corner.
Of course, these are all afterwords. Xue Weidong let go of the chatterbox again, and then hastily ended the popular science. It's no good not to end it, because yun-18nb has put down its landing gear and is about to land. Of course, he, the on-site commander, can't distract others.
However, in the airport, Xue Weidong put away his voice. On a high ground outside the airport, Li Ruihong kept barking with the wild dog who had lost his rein: "Mr. Zhuang, Mr. Ning, how dare they fall in such a short distance? You don't want to die? It's very easy for us to be affected when we are so close. We'd better go quickly, or we'll be in danger later. Money doesn't matter. It's important to keep our lives. No wonder Li Ruihong is so frightened. Yun-18, which landed just now, has a huge body, and a series of auxiliary transportation, loading and unloading equipment and support equipment account for almost one third of the total The landing distance of other aircrafts must be kept at a certain distance from the yun-18nb on the other side of the runway, so the landing distance of yun-18nb in the sky is 1000 meters.
The biggest take-off weight of 124 tons of big guy wants to land on the one kilometer runway. How can it be unreliable? What's more, Li Ruihong is on the vertical extension of the runway. Fortunately, they are just opposite to the running direction of yun-18nb landing.
If the distance of one kilometer is not stopped, yun-18nb rushes out and runs. Li Ruihong really doesn't know how to die.
As a result, Li Ruihong was held in place by Ning Xiaodong. He couldn't walk. He was almost crazy, so he had to persuade the two big men who were more crazy than him.
But before he finished his words, he saw Zhuang Jianye waving his hand indifferently: "the plane I built, I know, has short legs and can't go that far!"
