Chapter 1125

Take off products, must be fine.

Based on the original modular design of Yun 17, Tengfei group has added two extended cabin sections on the basis of the basic model of Yun 17, which makes the total length increase by 5 meters to 38.82 meters, thus obtaining more space for modification.

Based on this, after various optimizations, Tengfei group makes Yun 18 own a 22.3m long and 7.1m wide. It is a huge warehouse with a height of 6.8 meters and a total volume of 1076.6 cubic meters.

Don't underestimate this warehouse. The main transport aircraft used by the former Soviet Union and Russia today, the An-124 strategic transport aircraft, has a warehouse volume of 1148 cubic meters.

Only less than 100 cubic meters more than that of Yun 18, which shows how strong Yun 18 is in the transportation of large-scale goods.

As a matter of fact, it is true that the key large-scale equipment of the second artillery unit, such as the existing equipment, the equipment under research, and even the pre research equipment, such as the missile body, fuel storage tank, instrument cabin, loader, can be easily loaded.

Especially for the loading of Dongfeng V improved large-size shell, this kind of big guy with a diameter of 3.35 meters and a length of 20 meters is very difficult to transport by train or heavy truck, so that in the past, it can only be shipped in sections.

Even the special transport aircraft like yun-16 is not good, because the length of yun-16's warehouse is only 20.56 meters. Although the Dongfeng V improved large-size projectile can be loaded into yun-16's warehouse, it has no space for fixed cables, so it can't be loaded at all, so it can only be cut and loaded according to the specification of 18 meters.

However, in this way, there will inevitably be many more connection points during the final assembly, which will not only affect the safety of the missile, but also increase the total amount of unnecessary structure.

The appearance of yun-18 solves this problem very well. The 20 meter long big guy can be easily put into it, and can also be transported away together with the internal fuel tank, control equipment, navigation equipment and other accessories.

After all, the maximum carrying capacity of Yun 18 has reached 33 tons, which is 11 tons higher than the 22 tons of Yun 16 of the previous generation. Therefore, when carrying out transportation tasks, it can carry products with higher degree of completion, so as to improve production efficiency.

The cargo load has reached 33 tons, and yun-18 itself is also a heavyweight player, with an empty weight of 38 tons and a maximum take-off weight of 105 tons.

It has become the largest aircraft developed and produced by Tengfei group so far.

A few years ago, the threshold level of this large aircraft was over 80 tons, not to mention 100 tons. Tengfei group did not dare to touch it.

There's no way. It's the key manufacturing equipment for many large airplanes. Tengfei group has no choice but to say that there is also a blank in China. It has no place to do what it wants to do. It can only try its best to reduce the total amount of structure and make a turn under 80 tons.

However, all this, together with a batch of professional equipment for large aircraft production provided by Russia's Tupolev Design Bureau, completely solved the problem of Tengfei group.

Although the original intention of the Russians is to jointly produce Tu-204 and take this opportunity to expand Russia's market share in the field of civil aviation airliner, this plan of Russia has been pushed to death by the aviation giants such as Boeing and Airbus. Fortunately, Tupolev has delivered the key equipment. Although it's a pity that Tu-204 can't be produced jointly, it's a pity for Tengfei group Opportunity to reach 100 tons, a target that I didn't even think of before.

As a result, the aviation engineers of Tengfei group, who used to haggle over everything, completely released themselves this time. If there were no restrictions on the second artillery, let alone the 100 ton class, even the 150 ton class might have been saved for you.

No way, who let the aeroengine of Tengfei group be ready for this day.

Wd-60ml-22 high bypass ratio turbofan engine.

Although Tu-204 project is still in its infancy, this turbofan engine with a maximum thrust of 12.5 tons and large bypass ratio has not stopped its research and development. It has been gradually improved under the promotion of Zhuang Jianye, and has been put into small batch production in recent years.

So the aviation designers of Tengfei group don't have the "power phobia" of other domestic counterparts at all. The wd-60ml-22 turbofan engine is there pitifully waiting for them to crush, trample and demand.

In addition to another key sector of Tengfei group, high-end aviation materials are also open to the outside world. These aviation engineers are not too happy.

In fact, a new aircraft has been built.

As a result, yun-17nb, which Zhuang Jianye named himself before, can't be used. It can only be used for one price and becomes yun-18.

After that, it took more than three years to complete the ground static test, whole machine structure test, flight test, evaluation and other aspects. During this period, naturally, there were also twists and turns, such as high-altitude tremor of the aircraft, occasionally insufficient thrust of the engine when taking off from plateau and so on.

Fortunately, Tengfei group has solved all the problems one by one, so it will create such excellent special transport aircraft in a short time.Of course, excellent performance does not mean that Yun 18 is uncertain. Almost like other products produced by Tengfei group, the biggest disadvantage of Yun 18 is its high cost.

The unit price of 560 million yuan directly broke the price record of domestic aircraft.

So that when the leaders of the Second Artillery received the final quotation, they almost went crazy. For 560 million one, six would be 3.36 billion yuan.

3.36 billion. How many missiles can we buy!

But in the end, the Second Artillery still bit their teeth and bought six. There was no way. Who could make yun-18 the only platform for dongfeng-v improved full-scale segmented and integrated transportation.

Moreover, in order to increase the reliability of the missile and reduce the segment connection, Dongfeng IV x, the next generation of subgrade mobile strategic missile of the second artillery, also needs to transport 18 segments.

Even if the land-based missile is not used, the sea based giant wave I and giant wave II, which require higher requirements, also need to be transported 18 to better solve their own transportation problems.

Because of this, even if yun-18 breaks the price record of domestic aviation products and directly pushes the upper limit to 500 million, the Second Artillery Force will still spend a lot of money to buy out the huge role yun-18 will play in the future.

In this respect, the leaders of the Second Artillery Corps are more generous than those of the headquarters.

Even if the second artillery was bought, the air force always wanted to make it clear. As a result, the head of the headquarters said, "this thing is not practical."

The idea of expanding sales of Tengfei group was completely cut off. Zhuang Jianye, who was as like as two peas in the

, was at the same time as the repacking officers in the airport at the moment. They were all surprised and confused. However, unlike Zhuang Jianye, the heavy loaded army cadres were the people in the army. After listening to Xue Weidong's unrealistic evaluation of Yun 18, he was slightly surprised, and nodded without any doubt: "indeed, Not to mention anything else, it's a bit embarrassing just to have a load of 33 tons. The battle of the army's type 88 tank is all about 38 tons, and the carrying capacity of at least 40 tons is barely enough, so Alas Now we don't have such a transport plane except for a few imported Il-76. "

"Who said no?"

When Xue Weidong heard the speech, he asked a meaningful question. As a result, when his voice fell, the sound of the engine in the sky roared, and immediately a four gray Universiade appeared in people's sight.
