Chapter 1247

The problem is that excitement comes back to excitement, excitement comes back to excitement. Zhuang Jianye couldn't get the hypersonic wind tunnel at all, so he said with a bitter face: "the wcnb-12 shock tunnel has just been assembled, and no further test has been done. The specific situation can only be known after a series of experimental verification. What's more, wcnb-12 is not in Xingzhou, but in cotton, It's still a long way from here... "

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

Without waiting for Zhuang Jianye to finish his speech, the leader of the army directly interrupted him and immediately turned to his confidential secretary: "you're going to arrange it, we're going to cotton."

After that, he walked out of the workshop without looking back. The head of the headquarters followed suit. Naturally, other members of the research group had no objection. After all, the leader of the army was the number one leader of the research group. No one dared to listen to what he said.

Zhuang Jianye is helpless. He can't leave after lunch because it's almost noon? Wcnb-12 shockwave wind tunnel is so big that it can't run on cotton. Is it in such a hurry?

Just these words, Zhuang Jianye dare to mutter in his heart. He can't wait to see the big leader in the army. He wants to fly by with his wings. If you tell him not to worry, he will have to worry with you.

I can't help it. I can only do things according to the rules. Fortunately, Zhuang Jianye had people bring some bottled instant noodles before he started. Otherwise, I really don't know how to get to the cotton.

After all, not everyone is the same as the leaders of the army and the head of the headquarters. When they heard that the wcnb-12 shock tunnel had been built, they were so excited that they could not eat or drink; Other technical leaders don't have such strong skills. They have to eat when they need to. For example, senior researchers, who are almost 80 years old, can't afford to be bumpy all the way. If they don't eat some energy, how can they survive?

Fortunately, all the way was smooth. When we arrived at the State Key Laboratory of wind tunnel in cotton, the research team was in good condition. Naturally, the military leaders took the lead and ran directly to the site of the newly completed wcnb-12 shock tunnel.

Soon they came to a large test site made of reinforced concrete and armored steel, and they were shocked by the long row of metal pipes in front of them.

"Ladies and gentlemen, this is the national key construction project undertaken by China Tengfei, wcnb-12 shock tunnel, with a total length of 265 meters, of which the length of the driving section is 99 meters and the inner diameter is 420 mm; The driven section is 89 meters and the inner diameter is 720 mm. By the way, the booster valve at the periphery of the driven section is made by nb-985plus Metal 3D printer integrated molding technology, and it is also the largest titanium alloy structural part with cross-sectional area produced by us so far. "

After inserting a sentence, Zhuang Jianye returned to the topic, Pointing to the wcnb-12 shock tunnel, he continued: "the nozzle outlet diameter is adjustable. When the diameter is 1.5m, it can be used for hypersonic test; When the diameter is 2.5m, it is used for hypersonic test.

The last part is that the length of the test section is 11 meters and the diameter is 3.5 meters. The whole wcnb-12 shock tunnel adopts the detonation driving system, which uses acetylene, oxygen and nitrogen to produce deflagration impact. Combined with the reduced driving inner diameter, the hypersonic and hypersonic jet can be realized... "

Zhuang Jianye's voice is slow, It reverberates slowly in the open wind tunnel test site, but every word sounds like a precipitous word to the military leaders and others.

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

What does that mean?

In the future, China will be able to do whatever it wants in the field of hypersonic, especially in the field of hypersonic. Maintaining national security will not only become more comfortable, but conquering the distant stars and oceans is not a distant dream.

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

When Zhuang Jianye was introducing the wcnb-12 shock tunnel, Professor Yu, who was in charge of the design and construction of the shock tunnel, came with a group of backbone members in a hurry.

There's no way. No matter how busy he is, no matter how busy he is, Professor Yu will take time to accompany him.

You know, not everyone here can enjoy this kind of treatment. Besides, Professor Yu's qualification and level are authoritative in the field of domestic wind tunnel, especially in the field of shock tunnel.

In his early years, he studied ballistic missile technology under the guidance of Qian Lao, the father of national missile. Later, he followed his tutor's advice and switched to the research of aerodynamic physics in near earth space.In the late 1960s and early 1970s, foreign anti missile technology was in the ascendant, especially the formal deployment and service of the A-35 anti missile defense system of the former Soviet Union, which stimulated the research and investment of countries in this field.

At that time, the domestic and foreign new models also launched a number of anti missile research and development projects. Among them, the anti missile No.1 and Xianfeng No.1 anti missile artillery were the two core systems of anti missile at that time.

However, both counterattack-1 and pioneer-1 need to study and test the aerodynamics of near earth space. In order to solve this problem, the higher authorities dispatched a group of backbone personnel such as Professor Yu to start the development of shock tunnel.

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

If we go along this route, we will continue to make progress in shock tunnel in China, and eventually complete the construction of a large shock tunnel at Mach 20.

However, the plan can't keep up with the changes. While the spring breeze of reform and opening up is blowing across the land, many military projects are facing a tough winter.

During this period, the subsequent shock tunnel project, together with a large number of costly projects such as counterattack-1 and pioneer-1, was launched.

Although the project was launched, Professor Yu's personal treatment was still good. After all, in the 1960s and 1970s, Professor Yu's contribution was there. Even if the counterattack-1 and pioneer-1 were not completed, many technologies of domestic long-range launch vehicles were finalized by the first generation shock wave wind tunnel.

Because of this, Professor Yu, who lost the project, was not put on the shelf. Instead, he was transferred to Beijing as the director of a certain research project. After the new year, he was promoted to the technical director of the national defense science, technology and Industry Administration in charge of the aerospace and pneumatic field, and became a leader in the technical field.

If it's someone else, it's estimated that he will lie on the credit book until he retires and enjoys his old age. However, Professor Yu is a special person, especially seeing that countries all over the world continue to make efforts in hypersonic and hypersonic fields. He is afraid that China will fall behind in this field. After that, Professor Yu keeps giving advice to his superiors and restarting the shock tunnel project.

At that time, every penny in China had to be broken into eight pieces to spend. How could we afford to invest in such a big gold gobbler?

What's more, even if they had money, it was impossible for them to spend money in this field because of the domestic and international situation at that time. After all, it was time to mix oil with the West. It would be good if they didn't turn swords into plows. How could they continue to forge new swords?

Is it not good to have more money to solve the problems of people's livelihood and keep up with the happy life of western developed countries
