"Academician Chen, how are you going to come up with an aircraft that can meet the requirements within a week? This is no child's play!" At the end of the meeting, representatives from scientific research institutions brought experts in aircraft R&D and manufacturing to Chen Xin and asked him Asked with concern.
On the side, your expert in aircraft R&D and manufacturing also frowned, because with his decades of work experience, he couldn't think of a reason why Chen Xin could guarantee to come up with a solution within a week.
The time required to design an aircraft has always been measured in years. The Y-9 transport aircraft was first launched in 1969 and was not officially unveiled until 2005.
Although there were various problems that led to the interruption of the research and development of the Y-9, the time required for aircraft development is also evident.
Even if Chen Xin only improves Yun 9, this is not something that can be completed in a week.
Regarding this problem, Chen Xin is certainly confident, but he also knows that the problem cannot be solved by just one plane.
And when they talk about an aircraft, they don’t mean just one, but a model, or a solution that can make a batch of existing aircraft fly in a short time to meet the requirements.
This may be impossible for others, but for Chen Xin, one week is enough.
"Please rest assured, I have already issued a military order in front of the leadership, so I will not joke about this kind of thing." Chen Xinchong smiled at the two people in front of him and explained to them: "Yun-9 is an aircraft with a very good design, and There is a ready-made template, and I don't need to make major changes based on it.
We only need to improve the aircraft's engine and air intake duct so that the aircraft can cope with the environment in front of us, and then we can meet the requirements and complete this mission.
Although one week is indeed a bit tight, I am still confident that I can handle this matter. "
"Although you say that, are you really sure, Academician Chen?" The expert confirmed to Chen Xin, but he was still very worried about whether Chen Xin could really complete the task: "I understand the design of Yun 9. If not, let me help you!"
"Thank you for your kindness, but you should also have important work to do on your side, right? Please believe me, since I dare to make a guarantee and issue a military order, I am confident enough to complete the task." Chen Xin declined the expert's kindness , there is a system to help Chen Xin feel confident enough to solve this matter by himself, and of course he does not need to waste other people's time to help himself.
Seeing how confident Chen Xin was, the representatives and experts had no choice but to acquiesce that he would complete the matter independently.
"Speaking of which, why not use an airship? Although the Zeppelin airship is a bit slow, 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.
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.
It was not until 1900, when Count Zeppelin of Hans built the world's first rigid airship, that this type of aircraft truly matured and began to shine.
Not only for civilian use, in an era when there were no airplanes, this large aircraft that could fly into the sky was also widely used in the military.
This also gave birth to the largest aircraft in human history-the Hindenburg airship.
This 803-foot-long behemoth has an extremely astonishing size and can accommodate 72 passengers. In that era when airplanes were not yet capable of flying across the Atlantic, it took only two days to fly to the other side of the ocean, and it took five days to complete the journey. At that time, the only way to cross the Atlantic Ocean was by cruise ship. It was extremely amazing.
Of course, the load capacity of such a large airship is not very high. At that time, in order to ensure the smooth launch of the airship, everything on the airship was reduced in weight, but the carrying capacity was still not high.
Although it has a huge size comparable to that of the Titanic, it has not carried more than a hundred people together with the staff at most.
Moreover, the Hindenburg suffered an air crash in 1937 and was completely burned down in just 32 seconds, which also announced the decline of the airship era. Since then, humans have never built a large airship, and relevant research has only gradually resumed in recent years. Re-emergence.
However, although airships have various problems, they can still play some role in the current environment where aircraft are not useful.
However, the representative shook his head and said with some helplessness: "Airships can indeed be used, but their price/performance ratio is too low. Soft airships are relatively cheap to build, but their payload is not high. It may not be a problem to transport a few people, but I want to Large rigid airships are still needed to transport supplies.
But the cost of building a large rigid airship... Not to mention the cost, once it is built, its carrying capacity and flying speed will not be good. It is better to build an old-fashioned propeller aircraft! "
"That's true..." Chen Xin touched his chin, and he really didn't expect this.
The representatives and experts saw that Chen Xin had made up his mind and had no intention of persuading him any more, so after saying a few words to speak if necessary, they left.
Soon after, the Y-9 design information Chen Xin needed was sent over, and the aircraft he needed was available at a combat readiness airport in Chongqing City.
In the past, the design data of Yun-9 could fill a Yun-9 with just the drawings, but now it can be done with only one hard drive.
Looking at the design drawings of Yun 9 in front of the computer, although Chen Xin didn't understand these things very well, he could still understand the drawings.
The Yun-9 itself can actually carry out flight missions in such harsh environments, but the key lies in the air inlet of the engine.
Even if the Yun-9 uses a turboprop engine, the demand for air intake is only slightly 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 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 could use system upgrades to directly change the engines on the aircraft to piston engines, it would still be a major project to replace all 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 requires a small investment. Otherwise, although it is not useless, it will not be so practical for the country.
After all, if it is to replace the engine, the cost and time of the engine replacement and the cost and time of engine production are a huge consumption. In the current crisis situation, 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 aircraft's air intake duct and install an air filter device, just like what was done on the helicopter.
You must know that after the Toba volcano erupts, in addition to the dust and particles brought by previous meteorite impacts, there will be a large amount of volcanic ash suspended in the air.
