Chapter 221 Two Bomb City

Jiang Fan threw out this question, and everyone began to express their opinions.

Someone at the meeting said: "I think this issue should be carefully considered. According to the performance of the latest JF-22 ultra-high-speed wind tunnel equipment just mentioned, we can re-select the site and find the most suitable natural conditions for its deployment to achieve the best performance. Good assembly effect.

Because this wind tunnel will not only be used by us in the future, but will also be used in aerospace and missile testing.

Especially missiles, as everyone knows, our Dongfeng 17 ballistic missile is a hypersonic missile with a speed exceeding Mach 10.

And the waverider warhead it uses can glide and fly at the edge of the atmosphere, and walk out of the well-known "Qian Xuesen ballistic", making it difficult for opponents to intercept. It also relies on the simulation of airflow by wind tunnel tests done on the ground.

Therefore, I think a round of comprehensive investigation and site selection should be conducted to select the best natural conditions to build this wind tunnel base. "

The speaker's words were recognized by many people. In the field of aerospace, wind tunnel tests play an inestimable role in improving the safety of aircraft.

Such important equipment should naturally achieve the best results after assembly.

However, some people raised objections, saying: "This idea is not a problem, but we must also consider the practical feasibility and investigate all possible places. Not to mention how much manpower and material resources will be spent, I don't know how much time it will take.

One year, two years, or longer?
Not to mention that our project is almost definitely affected, the test results of other spacecraft and aircraft projects during this period will inevitably be greatly reduced.

Therefore, we should not only consider technical factors, but also consider time costs, personnel costs and supporting costs.

Our existing supporting facilities and human resources have been built around the site selection of the existing wind tunnel for many years. If we choose a new place, we need to move a large number of experts and people to the past, and we need a large amount of money to build supporting facilities. Facilities, not worth it.

Therefore, my suggestion is to choose one of our current wind tunnel test bases and build them based on the natural environment there.

Those places were strictly inspected in those years and were suitable for building wind tunnels in all aspects. Even if it was not the optimal solution, it was at least the suboptimal solution. Choose one of the five wind tunnel bases across the country. "

His point of view is recognized by more people, including experts who proposed JF-22 also added:
"Our equipment is also developed with environmental adaptability in mind. It is not so delicate. As long as it is in a relatively good natural environment, it can guarantee 100% installation effect."

The expert's words hammered the final word on this topic, and the focus of everyone's consideration was on the locations of the five existing wind tunnel laboratories.

Jiang Fan has learned about these experimental bases, and at this time also made suggestions:

"How about putting it in the Jilin Wind Tunnel Laboratory? In addition to commercial large-bypass ratio aviation engines, our project this time also includes small-bypass ratio aviation engines for fighter jets.

And Shen Fei is specialized in fighter jets, and J15 and J16 were developed by them. Later, when they participated in the research and development of this project, the wind tunnel base was closer, and it was more conducive for them to do related wind tunnel tests. Improve efficiency. "

After pondering Jiang Fan's words, the dean also put forward his opinion: "The idea proposed by Chief Designer Jiang is a good idea, and there is an old industrial base in the Northeast, so we need to consider the agglomeration of industries.

However, according to this idea, the Jilin Wind Tunnel Laboratory is not the best choice.

On the contrary, Mianyang Wind Tunnel Group in Sichuan Province is a better choice.

First of all, let's talk about its status. It is the largest aviation wind tunnel test center in Asia and one of the three wind tunnel groups with the strongest performance and most complete functions in the world.

Therefore, the JF-22 built here can further improve its one-stop test function. Any aircraft does not need to be pulled around for testing, and can be tested in various situations at one time here.

The second is the aggregation that Chief Designer Jiang mentioned just now. Cheng Fei, who is as famous as Shen Fei, is also very close to Sichuan Province, and has also participated in the research project of this aircraft fighter module.

The achievement of Chengfei is J20, which has more advanced technical strength. What we tested this time based on the basic data is also the above combination and creative ability.

Therefore, it is more likely that the cost will take the lead, and such intensiveness is more practical.

And even from the perspective of talents, the Ninth Academy, the Institute of Engineering Physics, and the Institute of Aerodynamics are all here, which is the place with the most academicians besides the imperial capital.

So on the whole, I think the Mianyang Wind Tunnel Group in Sichuan Province may be a more suitable place for our latest wind tunnel installation. "

The dean's words were actually a tactful rejection of Jiang Fan's suggestion, but Jiang Fan was not angry, he was considering this issue entirely out of a public heart, otherwise, as his hometown, he should have favored Sichuan Province more.

The dean's suggestion was thoughtful as a whole. Jiang Fan first raised his hand to express his agreement, and after some exchanges, the others also expressed their agreement.

At the end of the meeting, the latest wind tunnels for high-thrust aeroengines were decided to be built in the Mianyang Wind Tunnel Group in Sichuan Province.

After the meeting, Jiang Fan handed over the resolutions of this meeting, and as long as Jiang Fan's proposals were made, they all skipped layers of approval and went straight to the top.

So it only took half a day for the relevant coordination and construction units to receive the instructions, and the original draft of Jiang Fan's resolution was attached. The instructions only had two words: do it!
Under the pressure of the first-level order, all relevant units implemented this matter as a first-level task, and all the departments involved also gave the green light all the way to ensure that this matter would not be delayed in the slightest.

Soon, it only took 2 months. With our super mobilization and infrastructure capabilities, the entire latest JF-22 ultra-high-speed wind tunnel has been basically completed.

As the chief designer of the aviation development project, Jiang Fan also came to inspect the site in person at the invitation of the director of the aviation development institute.

Although it belongs to Sichuan Province, Jiang Fan has never been to this area, so he is very interested.

Under the introduction of the person in charge inside, he had an understanding of the vacuum chamber, test chamber, nozzle and other facilities, and actually watched the test demonstration. The whole experiment was almost the ultimate destruction of the aircraft.

According to the person in charge, we have done more than 47 such experiments.

It is precisely because of such a large number of experiments that we have successfully solved a large number of key technologies including the return capsule of the Shenzhou manned spacecraft, the aerodynamic force and aerodynamic heat of the escape vehicle, and the key aerodynamic problems of other aerospace vehicles and weaponry.

Jiang Fan felt that this trip was very fruitful. When he returned, Jiang Fan saw a courtyard not far away at the foot of the mountain, which seemed to have a lot of history, and asked the dean, "Where is that place?"

The dean looked at it, pondered for two seconds, and then said slowly: "That is. Two bomb city!"
