Doomsday Bunker Upgrade Chapter 427: How to get started

"Academician Chen, how do 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&D and manufacturing to find Chen Xin , 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 think of the reason why Chen Xingan promises to come up with a solution within a week.

The time limit for designing an aircraft is always measured in years. The Yun-9 transport aircraft was first approved in 1969, and it was not officially unveiled until 2005.

Although there are various problems in the middle that have interrupted the research and development of the Y-9, the time required for the development of the aircraft is also evident.

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

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

And when they say a plane, they don't 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 leader, so I won't joke about this kind of thing." Chen Xinchong smiled and explained to them: "The Yun 9 is a very good design. The plane, and has a ready-made model, I don't need to make any major changes to the base.

Only need to improve the engine and intake duct of the aircraft, so that the aircraft can be competent for the immediate environment, then it can meet the requirements and complete this mission.

Although the week is indeed a bit tight, I'm still confident that I'll get this done. "

"Although you say so, but Academician Chen, are you really sure?" 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 also count the design of Yun9. Understood, or I'll 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 promise to issue a military order, I have enough confidence to complete the task." Chen Xin declined. With the kindness of the experts, there is a system to help Chen Xin with sufficient confidence to solve this matter by himself. Of course, he does not need to waste other people's time to help himself.

Seeing Chen Xin's confidence, the representatives and experts had no choice but to acquiesce in his decision to 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 was a little puzzled asked the representative.

Airships first appeared in the 19th century. Although they were indeed a new type of aircraft at the time, they were not very mature and practical.

The small book kiosk used by book lovers has been hung up, and now they are basically using mimireadingapp\.

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

Not only for civilian use, but in the era when there were no airplanes, this kind of large 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 hold 72 passengers. In an 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 whole journey, in that era when crossing the Atlantic could only be done by cruise ships, was 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, it does not carry a hundred people along with the staff.

And with the air crash of the Hindenburg in 1937, it was completely burned in just 32 seconds, which also announced the decline of the airship era. Since then, no large airship has been built by humans, and related research has also been carried out in recent years. Only gradually re-emerged.

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

However, the representative shook his head and said somewhat 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 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 to ~IndoMTL.com~ and the aircraft he needed was available at a combat-ready airport in Yu City.

In the past, the design data of the Y-9 could be filled with the blueprints alone, but now only one hard drive is needed.

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 mission in such a 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 four engines on 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 not possible to replace it with a piston engine. Very likely.

Even if Chen Xin could use a system upgrade to directly change the engine on the plane to a piston type, it would be a big project to replace all the planes in the country.

So 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 the engine production are all a huge consumption. In the current situation of facing a crisis, there is no time to work slowly and meticulously.

So 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 as he did on a helicopter.

Be aware that after the eruption of Mount Toba, 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.
