Chapter 428

"Academician Chen, how do you take out a plane that can meet the requirements within a week? This is no joke At the end of the meeting, representatives of scientific research institutions, together with experts in aircraft R & D and manufacturing, found Chen Xin and asked him with concern.

Your expert in aircraft R & D and manufacturing is also frowning, because with his decades of work experience, he can't figure out why Chen Xin dares to come up with a solution in a week.

The number of years for designing an aircraft has always been based on years. Yun-9 transport aircraft was first approved in 1969, and it didn't officially appear until 2005.

Although there are all kinds of problems in the middle that lead to the interruption of the research and development of yun-9, the time needed for aircraft research and development can also be seen.

Even if Chen Xin only makes improvements on Yun 9, it's not something that can be accomplished in a week.

Of course, Chen Xin has a good idea of this problem, but he also knows that the problem can not be solved by one plane.

What they say about an aircraft is not a simple one, but a model, or a solution that can make a batch of ready-made aircraft fly in a short time.

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

"Please don't worry, I have already set up a military order in front of the leaders, so I won't make fun of this kind of thing." The two in front of Chen Xinchong's eyes laughed and explained to them, "yun-9 is a very well-designed aircraft with ready-made models. On the basis of it, I don't need to make any major changes.

We only need to improve the engine and intake duct of the aircraft, so that the aircraft can be competent for the immediate environment, and then we can meet the requirements and complete the task.

Although it's a bit tight in a week, I'm confident that I can handle it. "

"That's what I said, but are you sure, academician Chen?" Experts confirm to Chen Xin, he is still worried about Chen Xin is really able to complete the task: "Yun 9 design I also know, or I'll help you!"

"Thank you for your kindness, but you should have some important work to do yourself? Please believe me, since I dare to make a pledge and set up a military order, I will have enough assurance to complete the task. " Chen Xin declined the expert's kindness, and had a system to help Chen Xin, who was confident enough to solve the problem himself. Of course, he didn't need to waste other people's time to help himself.

Seeing that Chen Xin is so confident, the representatives and experts have no choice but to acquiesce to his practice of completing this task independently.

"Why not use airships? The Zeppelin airship is a bit slow, but it should still be useful in this kind of environment? " Chen Xin thought of an old flying tool and asked the representative in doubt.

Airship first appeared in the 19th century. At that time, although it was a new type of aircraft, it was not very mature and practical.

It was not until 1900 that the Earl of Zeppelin of Hans built the world's first hard airship that this kind of aircraft really matured and began to shine.

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

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

The 803 foot giant has an amazing volume, which can accommodate 72 passengers. In the era when the plane was not able to fly across the Atlantic Ocean, it took only two days to fly to the other side of the ocean, and it took five days to complete the whole journey. At that time, it was amazing when only cruise ships could cross the Atlantic Ocean.

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

Although it has a huge size comparable to Titanic, but at most, together with the staff, it did not carry 100 people.

In 1937, the Hindenburg suffered an air crash, which completely burned down in a short time of 32 seconds. It also declared the decline of the era of airship. Since then, human beings have never built a large airship, and the related research has gradually re emerged in recent years.

However, although there are various problems with airship, it can still play a role in the current situation where this kind of aircraft can not be used.

However, the representative shook his head and said helplessly: "airships can really be used, but their cost performance is too low. The cost of soft airships is relatively low, but the load is not high. It may be no problem to transport a few people, but large hard airships are still needed to transport materials.

But the cost of a large hard airship Not to mention the cost, the carrying capacity and flying speed will not be good after it is built. It's better to build an old propeller airplane! "

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

When the representatives and experts saw that Chen Xin had made up his mind, they had no intention of persuading him again, so they said a few words when necessary, and then left.

Soon after that, the yun9 design materials Chen Xin needed were sent over, and the aircraft he needed was in a combat readiness airport in Chongqing.In the past, the design data of yun-9 could be filled with only drawings, but now it only needs a hard disk.

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

In fact, the Y9 itself can carry the mission in the current harsh environment, but the key lies in the air inlet of the engine.

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

Yun-9 has four engines in total. The turboprop-6c engine independently developed by Yanguo is used. Its output power is up to 5100 horsepower, or 3751kw. It is obviously impossible to replace it with a piston engine.

Even if Chen Xin can use the system upgrade to directly change the engine on the plane to piston type, 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 time and with little investment. Otherwise, although it is not useless, it is not so practical for the country.

After all, if it is a replacement, the cost and time of replacement and the cost and time of engine production are a huge consumption. In the current situation of facing crisis, there is no time for slow work.

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

You should know that after the eruption of DOPA 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.
