Previous page        Return to Catalog        Next page

    The problem is that excitement leads to excitement, and Zhuang Jianye simply cannot get a hypersonic wind tunnel, so he can only say with a grimace: "The wcnb-12 shock wave wind tunnel has just been assembled and no further testing has been done.  , the specific situation will only be known after a series of experimental verifications, not to mention wcnb-12 is not in Xingzhou, but is placed in Cotton, which is still far away from here"

    "What's wrong with putting it on cotton? Just go there!"

    Before Zhuang Jianye could finish his words, the military leader interrupted him and immediately turned to look at his confidential secretary: "Go and make arrangements right now, and we'll go to Cotton right now."

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

    Zhuang Jianye was helpless when he saw this. It was almost noon, so he couldn't leave after lunch?  wcnb-12 An object as big as a shock wave wind tunnel can't escape when placed in cotton. Why is it so urgent?

    It's just that Zhuang Jianye dared to mutter these words in his heart. He didn't see that the big leader in the army couldn't wait. He wished he could grow wings and fly over. If you tell him not to worry, the big leader will probably have to worry with you.  .

    "There is no other way but to follow the rules. Fortunately, Zhuang Jianye had someone bring some barreled instant noodles before departure, otherwise I really don't know how to hold on to the cotton.

    After all, not everyone is like the military leaders and headquarters chiefs. When they heard that the wcnb-12 shock wave wind tunnel was built, they were so excited that they could go without eating or drinking. Other technical leaders did not have such powerful skills.  You have to eat when you need to, especially a senior researcher who is almost 80 years old. It¡¯s a bumpy journey. If you don¡¯t eat something to replenish your energy, how can you survive?

    Fortunately, the journey was smooth. When they arrived at the National Key Laboratory of Wind Tunnel in Cotton, the research team was in pretty good condition. Naturally, the military leaders took the lead and rushed directly to the location of the newly completed wcnb-12 shock wave wind tunnel.  past.

    Soon everyone arrived at a large test site built of reinforced concrete and armored steel. When they entered, they were shocked by the rows of extremely long metal pipes in front of them.

    "Everyone, this is the national key construction project undertaken by China Tengfei, the wcnb-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, the boost valve at the outermost edge of the driven section is manufactured using the integrated molding technology of the nb-985plus metal 3D printer. It is also the titanium alloy structural part with the largest cross-sectional area that we have produced so far"

    After inserting a sentence, Zhuang Jianye returned to the topic and continued to point to the WCNB-12 shock wind tunnel and introduced: "The diameter of the nozzle outlet is adjustable. When the diameter is 1.5 meters, it is used for ultrasonic testing; when the diameter is 2.5 meters, it is used for ultrasonic testing.  Conduct hypersonic experiments.

    The last part is that the length of the test section is 11 meters and the diameter is 3.5 meters. The entire wcnb-12 shock wave wind tunnel adopts a detonation drive system, which uses acetylene, oxygen and nitrogen to generate deflagration impact. Combined with the reduced inner diameter of the drive, it can  Achieving hypersonic and ultra-hypersonic jets"

    Zhuang Jianye¡¯s voice was neither fast nor slow, echoing slowly in the empty wind tunnel test site, but every word sounded as heavy as a thousand stones to the military leaders and others.

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

    What does this mean?

    From now on, the country will be able to do whatever it wants in the field of hypersonics, especially ultra-hypersonics. Not only will it become easier to maintain national security, but conquering the distant stars and seas will not be an unattainable dream.

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

    When Zhuang Jianye was introducing the wcnb-12 shock wave wind tunnel, Professor Yu, who was responsible for the design and construction of the shock wave wind tunnel, hurried over with a group of backbones.

    "There is no way. If the military leader suddenly comes here, everyone must pay 200% attention. What's more, even if the military leader does not come, as long as Zhuang Jianye comes, Professor Yu will take time to accompany him personally no matter how busy he is.

    You must know that not everyone can enjoy this kind of treatment in Professor Yu. Not to mention, Professor Yu is an authoritative presence in domestic wind tunnels, especially in the field of shock wave wind tunnels, both in terms of qualifications and level.

    In his early years, he studied under Qian Lao, the father of China¡¯s missiles, and engaged in technical research on ballistic missiles. Later, he followed his mentor¡¯s advice and switched to aerodynamic physics research 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 around the world.

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

    However, both Counterattack 1 and Pioneer 1 need to conduct research and experiments on the aerodynamics of near-Earth space. In order to solve this problem, superiors mobilized Professor Yu and a group of backbones to start the development of shock wave wind tunnels.

    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 aircraft at Mach 2 to Mach 7.

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

    However, the plan could not keep up with the changes. While the spring breeze of reform and opening up was blowing on the earth, many military projects were facing a difficult winter.

    The follow-up shock tunnel plan was canceled during this period, along with a large number of costly projects such as Counterattack 1 and Pioneer 1.

    Although the project was discontinued, Professor Yu's personal treatment was still good. After all, Professor Yu's contribution was there in the 1960s and 1970s. Even if Counterattack 1 and Pioneer 1 were not completed, many of the domestic long-range launch vehicles had  The technology is indeed finalized through experiments completed in the first-generation shock wave wind tunnel.

    Because of this, Professor Yu, who lost the project, was not shelved. Instead, he was transferred to the capital to serve as the person in charge of a certain research. In the next year, he was promoted to the technical person in charge of the aerospace aerodynamics field of the National Defense Science and Technology Bureau.  Become a leader in technology.

    If it were anyone else, he would probably rest on his laurels until he retires and enjoys his old age, but Professor Yu is a very special person, especially seeing that countries around the world are continuing to make efforts in hypersonics and ultra-hypersonics, for fear that domestic  Professor Yu, who was lagging behind step by step in this regard, kept making suggestions to 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 and spent. How could there be money to invest in such a big gold-eating beast?

    What's more, even if you have money, it is impossible to spend money in this field due to the domestic and international situation at the time. After all, it was the time when the West was mixing honey with oil. It would be good if you did not turn swords into plowshares. How could you continue to forge new ones?  A sharp sword?

    With this money, wouldn¡¯t it be better to solve real people¡¯s livelihood problems and live a happy life on par with Western developed countries?
