Chapter 427: How to proceed

"Academician Chen, how do you come up with an aircraft that can meet the requirements within a week? This is not a child's play!" At the end of the meeting, representatives of scientific research institutions brought experts in aircraft R&D and manufacturing to Chen Xin and asked him Inquired with concern.
Your expert on aircraft R&D and manufacturing is also frowning, because with his decades of work experience, he can't think of the reason why Chen Xin can guarantee a solution within a week.
The number of years for designing an aircraft has always been in units of years. The Yun-9 transport aircraft was first established in 1969, and it was officially unveiled in 2005.
Although there are various problems in the middle that have caused the development of Yun 9 to be interrupted, the time required for the development of the aircraft is also evident.
Even if Chen Xin just made improvements on Yun 9, this is not something that can be accomplished in a week.
Of course, Chen Xin knew everything about this problem, but he also knew that the problem could not be solved by a single plane.
Moreover, what they are talking about does not mean a mere one, but a model, or a solution that allows the current batch of ready-made aircraft to fly in a short period of time.
This may be impossible for others, but for Chen Xin, one week is enough.
"Don't worry, I have made a military order in front of the leader, so I won't make jokes about this kind of thing." Chen Xinchong smiled and explained to them: "Yun 9 is a very well-designed aircraft, and There is a ready-made model, based on which I don’t need to change it.
It is only necessary to improve the aircraft's engine and intake ducts so that the aircraft can meet the immediate environment and meet the requirements to complete this mission.
Although one week is indeed tight, I still have the confidence to handle this matter. "
"Although it is said that, but Academician Chen, are you really sure?" The expert confirmed to Chen Xin. He was still very worried about whether Chen Xin could actually complete the task: "I understand the design of Yun9. No, let me help you!"
"Thank you for your kindness, but you should also have important work to do on your side? Believe me, since I dared to make a promise to 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 delay others' time to help himself.
Seeing that Chen Xin was so confident, the representatives and experts had no choice but to acquiesce in his own way of doing this independently.
"Why don't you use an airship? Although the Zeppelin is a bit slow, it should still be useful in this environment?" Chen Xin thought of an ancient flying tool, and he was a little confused. Asked.
The airship first appeared in the 19th century. Although it was indeed a new type of aircraft at the time, it was not very mature and practical.
The book booths that the book friends used before have gone down, and now they are basically using \Mic\Mic\Reading\app\\.
It wasn't until 1900 that Earl Zeppelin of Hans built the world's first rigid airship, that this kind of aircraft really matured and began to shine.
Not only for civilian use, this large aircraft that can fly into the sky has also been widely used in the military in the era when there was no aircraft.
This also gave birth to the largest aircraft in human history-the Hindenburg airship.
This 803-foot-long behemoth has an astonishing size and can accommodate 72 passengers. In the era when the plane was not yet capable of flying across the Atlantic, it could fly to the other side of the ocean in just two days and complete the journey in five days. At that time, the era when the only way to cross the Atlantic was to rely on cruise ships can be said to be incredibly amazing.
Of course, the load capacity of such a large airship is actually not high. At that time, in order to ensure the smooth lift-off 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 burnt down in just 32 seconds and also announced the decline of the airship era. Since then, humans have never built large airships, and related research has only gradually changed in recent years. Rise again.
However, although the airship has various problems, it can still play some role in the current environment where this kind of aircraft is not useful.
However, the representative shook his head and said helplessly: "Airships can indeed come in handy, but their price-performance ratio 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 I think Large rigid airships are needed to transport materials.
But the cost of a large rigid airship...not to mention the cost, after it is built, the carrying capacity and flying speed will not be good. It is better to build an old-fashioned propeller plane! "
"That's also..." Chen Xin touched his chin, really did not expect this.
Seeing that Chen Xin had made up his mind, the representatives and experts had no intention of persuading anymore, so after saying a few words as needed, they left.
Soon afterwards, the Yun 9 design materials needed by Chen Xin were sent over. com and the aircraft he needs are available in a combat-ready airport in Chongqing.
If it were in the past, the design data of the Yun9 could be filled with drawings alone, but now it only needs a hard drive to do it.
Looking at the design drawings of Yun 9 in front of the computer, Chen Xin did not understand these things, but the drawings could still be understood.
Yun 9 itself can actually carry the flight mission in this harsh environment, but the key lies in the air intake of the engine.
Even if Yun 9 uses a turboprop engine, the demand for air intake is only a little bit smaller than that of a turbojet engine.
There are a total of four engines on Yun9. The model used is a turboprop-6C engine independently developed by Yanguo. 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 use the system upgrade to directly change the aircraft's engine to a piston type, it would be a big project to replace all the aircraft 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 does not invest much. 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 a crisis, there is no time to work slowly.
Therefore, for Chen Xin, the best way to solve the problem is of course to improve the intake duct of the aircraft and install an air filter device, as it did on a helicopter.
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.
