The reason why the aerospace department and the Ascendas Group used the retired Il-18 passenger aircraft to convert such an alternative transport aircraft was mainly because of the impetus of practical needs.

If the enterprises placed in the aerospace sector system, it is estimated that there may not be such a demand in another one or two decades, mainly because these aerospace enterprises had a complete supporting plan when they were built, and the relevant supporting plants, assembly plants, test sites, and launch sites were connected by special railway lines.

After the large parts of the launch vehicle leave the factory, the point-to-point straight line arrival of the freight train for direct hoisting can be convenient, fast and efficient.

The problem is that this set will not be played in Tengfei Group.

Because Tengfei Group grew up completely on its own, in order to survive in the early stage, it is impossible to consider such a perfect supporting plan in the planning era, as long as it can be produced, raw materials and products can be smoothly transported.

What kind of special railway line, the struggling Tengfei Group really does not have the ability to do it, and at the same time, it is impossible for the railway department to invest in the development of special lines because of an ordinary enterprise.

Of course, the products of Tengfei Group at that time were enough for ordinary rail and road transportation, and there was no need to do anything special.

Not enough, since the production task issued by the aerospace department four years ago, everything has completely changed, because the Tengfei Group undertakes the processing and production of the second-stage fuel tank of a certain carrier rocket and the first-stage fuel tank of a certain type of missile, as well as part of the missile body.

Originally, it was not the turn of Tengfei Group to do these things, and there are many enterprises under the aerospace department, and some of them are factories that can undertake such tasks.

However, due to the failure of one space launch mission and the failure of two missile test launches, the space system found that the processing accuracy of the supporting plant did not meet the design requirements of a certain carrier rocket and a new missile.

On the one hand, it is the aging of the equipment of the supporting factory, and on the other hand, it is also the design index of the two models that are too high.

The introduction of equipment and comprehensive transformation is not impossible, but it takes time, which has a very huge impact on space launch and national defense security, so the head of the old headquarters who had not yet retired at that time accepted the appointment of the headquarters and personally made a survey in various enterprises in the space sector to see if he could concentrate the advantages of each factory and solve this problem, and even made preparations to build a new factory at any cost.

Tengfei Group, as the existence of the two major businesses of aviation and aerospace, is naturally the object of the old headquarters head, and it doesn't matter if it looks at it, although it is not as shocking as when he first came to Tengfei Group to inspect it, but it still refreshes his perception of Tengfei Group.

In particular, the Tengfei Aviation Technology R&D Center located in Xingzhou, the internal composite material achievements can simply blind people's eyes, and that's it, the key is that the supporting production equipment and processing technology Tengfei Group has also engaged in a seven, seven, eighty, eight, and eight, and with its own good production and processing capacity, what kind of factory will be built?

Hearing this result, Zhuang Jianye, who accompanied the head of the old headquarters to inspect, almost stopped crying.

He is not doing so much because he wants to do aerospace, but because he is ready to take advantage of the aerospace department to eliminate old equipment, engage in industrial upgrading, and become a supplier of materials and equipment as before, making a low-key and luxurious profit.

It is precisely because of this that when the head of the old headquarters came over, Zhuang Jianye would do his best to take out all the things at the bottom of the box, and he thought that the head of the old headquarters would smash all the words in his hands.

Zhuang Jianye, a real man, almost didn't cry and fainted in the toilet.

Of course, no matter how much you cry and wipe your tears in the toilet, you still have to listen to the words of the head of the old headquarters, not to mention that this is the will of the country, not something that can be measured by money, so soon after the head of the old headquarters left, Tengfei Group began to trial produce large components of the aerospace department in the Xiping factory.

In less than half a year, the second-stage fuel tank of a certain carrier rocket and the first-stage fuel tank of a certain type of missile produced by the Tengfei Group and some of the missile bodies have all met the design standards, and have passed the examination and approval of the expert group of the aerospace department, and can be mass-produced.

And then...... Here's the problem.

The diameter of such parts is generally two to three meters, or even larger, and the smallest length is 8 or 9 meters, among which the diameter of a certain type of missile body is 3.5 meters, and the length is 17.4 meters, and it needs to be integrally formed.

Such a large structural part has exceeded the length of the ordinary freight train car, and it needs a special carriage to be shipped, which is just that, the key is that these big guys are all precision parts, and it is not an exaggeration to say that they are as delicate as a baby, and they can neither knock nor touch during transportation and transshipment.

In this regard, the weakness of the imperfect planning of Tengfei Group in the early stage is highlighted, there is no dedicated railway, highway line, even if it is located in the southwest terrain is still very complex, tunnels, curves are so many that people doubt life, such road conditions want to ensure that large precision structural parts do not have problems, it can simply look like a world record.

What to do?

The answer given by Ascendas Group was to use airplanes for air transportation, and soon came up with a highly feasible solution.

There were limitations in land transportation, and there was no way to transport it by ship without relying on the sea, so aviation seemed to be the only option, so the aerospace department discussed it, and finally the head of the old headquarters made the decision to set up the project for transportation.16

For the sake of this project, the Tengfei Group, which undertook the task of refitting, even suspended the advanced light transport aircraft project that continued to advance, concentrated all its efforts and came up with the most pressing technology in recent years, which took nearly two years, and finally changed the two Il-18 retired air force planes to one that even the Soviet Union's Ilyushin Design Bureau, my own mother.

There is no way, in order to be able to install such large structural parts as the missile body, the fuselage has been subversively expanded by Tengfei Group, forming a huge cargo warehouse with a length of 20.56 meters, a height of 5.9 meters, a width of 5.9 meters, and a volume of 713 cubic meters, which can easily accommodate large structural parts such as launch vehicles or missile bodies produced by Tengfei Group.

Once the two "air cars" were used, they were immediately praised by the aerospace department, and the demand was extremely rising, counting the entire transport helicopter of the Tengfei Group to the Xiangzhou assembly plant, as well as the transportation tasks of precision parts in other aspects, the two "air cars" were in short supply.

The damaged JT9D engine of the Boeing 767 was still transported with the aerospace department to have a chance, otherwise it may not be able to be delivered when.

Of course, Zheng Yongning will not tell Wang Huan about these things, after all, when it comes to aerospace manufacturing, especially the production of a new type of missile body, not everyone can come into contact with it, even with the help of Zheng Yongning, Zhuang Jianye, many details are not clear, and outsiders cannot say so much in detail.

It's just that in order to facilitate the rapid transfer of various precision parts in the group, two Il-18s were specially modified at a huge cost.

But even so, Wang Huan was still very surprised, felt that Tengfei Group's hand was not ordinarily big, and was about to ask two details of the "air car", when he heard a roar of the engine in the sky, Wang Huan subconsciously raised his head, only glanced at his body is a shock, no way it is really the appearance of the plane is too weird, weird can not be described in words, can only point to the stupid and cute plane above and ask: "That's ......"

Zheng Yongning replied with a smile: "Ah, that's our 'air car' special transport aircraft." ”
