Take Off My Aviation Era

  Chapter 1247-12 Shock Wave Wind Tunnel

The problem is that excitement returns to excitement, and excitement returns to excitement. Zhuang Jianye can't take out the supersonic wind tunnel at all, so he can only say with a bitter expression: "-12 shock wave wind tunnel has just been assembled and has not yet been tested. The specific situation will not be known until after a series of experimental verifications. What's more, -12 is not in Xingzhou, but is placed in Cotton. There is still..."

   "What happened to the cotton? Just go straight to it!"

   Before Zhuang Jianye could finish speaking, the military leader interrupted his words, and immediately turned his head to look at his confidential secretary: "You go to make arrangements, we will go to Cotton."

After speaking, he walked out of the workshop without looking back. The head of the headquarters followed suit. The other members of the research team naturally had no objection. After all, the military leader was the number one leader of the research team. He made a speech. No one dares not listen.

  Zhuang Jianye was helpless when he saw this. It was almost noon when he saw it, so he couldn't leave after lunch? —12 If an object as big as the shock wave tunnel is placed in cotton, it can’t run. Is there such a hurry?

It’s just that Zhuang Jianye dared to mutter in his heart. He didn’t look at the leaders of the army and couldn’t wait. He wished he had wings and flew over. If you tell him don’t worry, I guess the leader will have to worry about you. .

  There is no other way but to do things according to the rules. Fortunately, before Zhuang Jianye set off, someone brought some buckets of instant noodles, otherwise I really don’t know how to get the cotton.

After all, not everyone is the same as the military leaders and the heads of the headquarters. I heard that the -12 shock wave wind tunnel was completed. It was so exciting that it was really unnecessary to eat or drink; other technical leaders do not have such powerful skills. You have to eat, especially like a senior researcher, who is about to make the 80s old people bumpy all the way. If you don’t eat a little bit to replenish your energy, how can you survive?

Fortunately, the road went smoothly. When the research team arrived at the National Key Laboratory of Wind Tunnel in Cotton, the status of the research team was not bad. The military leaders naturally took the lead and rushed directly to the location of the 12 shock wind tunnel that was just completed. .

   Soon everyone came to a large test site built of reinforced concrete and armored steel. With the help of it, everyone was shocked by the extremely long series of metal pipes in front of them.

"Everyone, this is the national key construction project undertaken by our China Ascendas, the 12 shock wave wind tunnel, with a total length of 265 meters, of which the driving section is 99 meters long and the inner diameter is 420 mm; the driven section is 89 meters and the inner diameter is 720 mm, by the way Let’s just say that the booster valve at the outermost periphery of the driven section is manufactured with the integrated molding technology of the NB-985Plus metal 3D printer. It is also the largest titanium alloy structural part with the largest cross-sectional area we have produced so far..."

After inserting a sentence, Zhuang Jianye returned to the topic, and continued to point to the 12 shock wave wind tunnel and introduced: "The nozzle outlet diameter is adjustable. When the diameter is 1.5 meters, it is used for supersonic testing; when the diameter is 2.5 meters, it is used for supersonic testing. Hypersonic test.

The last part is that the test section has a length of 11 meters and a diameter of 3.5 meters. The entire -12 shock wave wind tunnel uses a detonation drive system, which uses acetylene, oxygen and nitrogen to produce a deflagration impact, combined with a reduced drive inner diameter. Hypersonic and supersonic jets..."

  Zhuang Jianye’s voice was not swift and slow, and it echoed slowly in the empty wind tunnel test site, but every word sounded extremely important to the military leaders and others.

  The reason is very simple. The technical level of the -12 shock wind tunnel has reached the world's advanced level. In the world, only similar wind tunnels in the United States and Russia can compete with the -12 shock wind tunnel.

  What does this mean?

  In the future, China can do whatever it wants in the field of hypersonic, especially in the field of supersonic. It will not only become easy to maintain national security, but also conquer the distant sea of ​​stars is not an unattainable dream.

"Dear leaders, I only know so much about the -12 shock wave wind tunnel. After all, I am not a professional. This is the chief designer of the -12 shock wave wind tunnel, Professor Yu Zonglin. Let him talk about the specific situation. ."

  Zhuang Jianye is introducing the -12 shock wave wind tunnel, Professor Yu, who was in charge of the design and construction of the shock wave wind tunnel, hurried over with a team of backbones.

  There is no way, the military leaders suddenly come here, and everyone should pay 200% attention. Moreover, even if the military leaders do not come, as long as Zhuang Jianye comes, no matter how busy Professor Yu is, he will take the time to personally accompany him.

  You must know that not everyone can enjoy this kind of treatment here in Professor Yu, not to mention that Professor Yu is an authoritative existence in domestic wind tunnels, especially in the field of shock wind tunnels, whether he is seniority or level.

  In his early years, he studied under Qian Lao, the father of national missiles, and engaged in the technical research of ballistic missiles. Later, following the advice of his instructor, he switched to research on aerodynamics in near-Earth space.

  In the late 1960s and early 1970s, foreign anti-missile missile technology was in the ascendant, especially the formal deployment of the former Soviet Union’s A-35 anti-missile missile defense system, which stimulated research and investment in this area by countries all over the world.

  At that time, the domestic new style was between home and abroad, and a number of anti-missile missile research and development projects were also launched. Among them, the counterattack No. 1 anti-missile missile and the Xianfeng No. 1 anti-missile cannon were the two core anti-missile systems at that time.

  However, both Counterattack One and Pioneer One need to research and test the aerodynamics of near-Earth space. In order to solve this problem, a group of backbones such as Professor Yu from the superior began to develop the shock tunnel.

  After years of hard work, the first-generation shock wind tunnel was finally successfully developed in the late 1970s, which can simulate the operation of the aircraft in the state of Mach 2 to Mach 7.

  If you follow this route, domestic shock wave wind tunnels will continue to make progress, and finally the construction of a large shock wave wind tunnel around Mach 20 will be completed.

  However, the plan could not keep up with the changes. While the spring breeze of reform and opening up was blowing across the land, many military projects ushered in a difficult winter.

  The subsequent shock wave wind tunnel plan was discontinued in this period along with a large number of costly projects such as Counterattack One and Pioneer One.

Although the project was discontinued ~www.readwn.com~, Professor Yu’s personal treatment was still good. After all, Professor Yu’s contribution was placed there in the 1960s and 1970s. Even if the counterattack 1 was not completed and the Pioneer 1 was not completed, the domestic Many technologies of China's long-range launch vehicle are indeed finalized by the tests completed by the first-generation shock tunnel.

Because of this, Professor Yu, who lost the project, was not put on the shelf. Instead, he was transferred to the capital and served as the head of a certain research. After the new year, he was promoted to the head of technology in the aerospace and aerospace field of the National Defense Science and Industry Bureau. Become a leader in technology.

If it’s someone else, it’s probably just lying on the book of credit until retirement and enjoying his twilight years, but Professor Yu is a special axis person, especially seeing that all countries in the world continue to exert efforts in hypersonic and supersonic speeds, for fear of domestic In this regard, Professor Yu, who has fallen behind one step at a time, has continued to advise his superiors to restart the shock wave wind tunnel project.

  At that time, every penny in the country had to be broken into eight petals to spend, how can one have the money to invest in such a big gold swallowing beast?

What's more, even if you have money, it is impossible to spend money in this field based on the domestic and foreign situation at the time. After all, when you were mixing oil with the West at that time, it was not bad to turn your sword into a plow. Sharp sword?

  Have the money to solve the real problems of people’s livelihood, is it not good to be in line with the happy life of western developed countries?
