Doomsday Bunker Upgrade

"Academician Chen, how can you come up with an aircraft that can meet the requirements within a week? This is no child's play!" After the meeting, representatives of scientific research institutions brought experts in aircraft R\u0026D and manufacturing to find Chen Xin and asked him to asked with concern.

On the other hand, your expert in aircraft R\u0026D and manufacturing is also frowning, because with his decades of work experience, he can't think of the reason why Chen Xingan promises to come up with a solution within a week.

The time limit for designing an aircraft has always been based on years. The Yun-9 transport aircraft was first established in 1969, and it was not officially unveiled until 2005.

Although there were various problems in the middle, which led to the interruption of the research and development of the Yun-9, the time required for the development of the aircraft was also evident.

Even if Chen Xin is only improving on Yun 9, this is not something that can be completed in a week.

For this problem, Chen Xin is of course confident, but he also knows that the problem cannot be solved by a plane.

And when they say a plane, they do not mean a simple plane, but a model, or a solution that can make the current batch of ready-made planes fly in a short period of time.

This may be impossible for others, but for Chen Xin, a week is enough.

"Please rest assured, I have already issued a military order in front of the leaders, so I won't make fun of this kind of thing." Chen Xinchong smiled and explained to them: "The Yun-9 is a very well-designed aircraft, and There is a ready-made boilerplate that I don't need to overhaul at all.

It is only necessary to improve the engine and intake duct of the aircraft, so that the aircraft can be competent for the immediate environment, and then it can meet the requirements and complete this task.

Although it is indeed a little tight for a week, I am still confident that I can get this thing done. "

"Although that's what you said, are you really sure Academician Chen?" The expert confirmed to Chen Xin that he was still very worried about whether Chen Xin would really be able to complete the task: "I understand the design of Yun 9. No, let me help you!"

"Thank you for your kindness, but there should be important work to do on your own side, right? Please believe me, since I dare to make a guarantee and issue a military order, I have enough confidence to complete the task." Chen Xin declined the expert's kindness , there is a system to help Chen Xin have enough confidence to solve this matter by himself, of course, he does not need to waste other people's time to help himself.

Seeing that Chen Xin was so confident, the representatives and experts had no choice but to tacitly acquiesce that he would complete this matter independently.

"Why don't you use an airship? Zeppelin is a bit slow, but it should still be useful in this environment, right?" Chen Xin thought of an ancient flying tool, and asked the representative with some doubts asked.

The airship first appeared in the 19th century. Although it was indeed a new type of aircraft at that time, it was not very mature and practical.

It was not until 1900, when Hans' Earl Zeppelin built the world's first rigid airship, that the aircraft really matured and began to shine.

Not only for civilian use, but in the era when there were no planes, this kind of large-scale aircraft that could fly to the sky was also widely used in the military.

This also gave birth to the largest aircraft in human history, the Hindenburg airship.

The 803-foot-long behemoth has an incredible size and can accommodate 72 passengers. In the era when planes were not capable of flying across the Atlantic, it took only two days to fly across the ocean, and it took five days to run the entire distance. At that time, the era of crossing the Atlantic only by cruise ships can be said to be extremely amazing.

Of course, the load capacity of such a large airship is not high. At that time, in order to ensure the smooth launch of the airship, everything on the airship was reduced in weight, and the carrying capacity was still not high.

Although it has a huge size comparable to the Titanic, at most, together with the staff, it has not carried a hundred people.

Moreover, with the air crash of the Hindenburg in 1937, it was completely burned down in just 32 seconds, which also announced the decline of the airship era. Since then, humans have never built large airships, and related research has only been gradually renewed in recent years. re-emergence.

However, although the airship has various problems, it can still play some role in the current environment where the aircraft is not useful.

However, the representative shook his head and said helplessly: "Airships can really come in handy, but their cost-effectiveness is too low. Soft airships are relatively cheap, but the load is not high. It may be no problem to transport a few people, but I think Large rigid airships are still required to transport supplies.

But the cost of a large rigid airship... Not to mention the cost, the carrying capacity and flight speed will not be good after it is built, so it is better to build an old-fashioned propeller plane! "

"This is also..." Chen Xin touched his chin, but he really didn't think of this.

Seeing that Chen Xin had made up his mind and had no intention of persuading him, the representatives and experts said a few words if necessary, and then left.

Soon after, the Yun-9 design materials that Chen Xin needed were sent over, and the plane he needed was available at a combat-ready airport in Yu City.

If it was in the past, the design data of the Yun-9 could be filled with the drawings alone, but now only one hard disk can be done.

Looking at the design drawings of Yun 9 on the computer, although Chen Xin doesn't understand these things, he can still understand the drawings.

The Yun-9 itself can actually carry the flight mission in the current harsh environment, but the key lies in the air intake of the engine.

Even if the Yun 9 uses a turboprop engine, the demand for air intake is only a little smaller than that of a turbojet engine.

There are a total of four engines on the Yun-9. The model used is the turboprop-6C engine independently developed by Yan Guo. The output power is as high as 5100 horsepower, which is 3751KW. It is obviously impossible to replace it with a piston engine. .

Even if Chen Xin can directly change the engine on the plane to a piston type with a system upgrade, it is a big project to replace all the planes in the country.

Therefore, the solution that Chen Xin can provide must be a method that can solve the problem in a short period of time and requires little investment. Otherwise, although it is not useless, it will not be so practical for the country.

After all, if it is to replace the hair, the cost and time of the replacement and the cost and time of engine production are all a huge consumption. In the current situation of facing a crisis, there is no time to work slowly and carefully.

Therefore, for Chen Xin, the best way to solve the problem is, of course, to improve the air intake duct of the aircraft and install an air filter device as he did on a helicopter.

It should be known that after the eruption of the Toba volcano, in addition to the dust and particles brought by the previous meteorite impact, there will be a large amount of volcanic ash suspended in the air.

Do you want to build an airship? In fact, with the current technology and industrial manufacturing capabilities, this thing is not difficult to build, but the cost and cost performance are really not good.
