Vol 6 Chapter 3086: The strategic value of high-speed wind tunnels

Hearing Wu Hao's words, Qin Xinghe couldn't help but nodded. The blood that had hit Tianling Gai just now gradually faded away, and the whole person began to gradually calm down.

Indeed, he was a little too eager just now. Now that I think about it, I'm not very calm. A huge project like this cannot be developed in a short time.

If it were their aviation system, a huge project like this would probably take at least ten years.

For companies and individuals like Haoyu Technology and Wu Hao who are good at creating miracles, it will take them several years. This is not like making cars, mobile phones, or smart AR glasses. The supply chain is complete and the technology is mature. Basically, you only need to design the relevant solutions, and then you can manufacture them.

But this multi-functional orbiter is obviously not that simple. Not only must it successfully fly into space, but it must also land safely on the ground. This difficulty alone means that few countries and companies in the world can handle it. of.

Although there are some experiences and cases that can be learned from, there are too few that can be learned and helpful.

On the one hand, the object of reference is Laomi's space shuttle. Although it has been retired for more than ten years and almost twenty years, it is still the secret of Laomi's cutting-edge technology and equipment, and very little useful information can be obtained. Secondly, these space shuttles have been developed, produced and used for almost half a century.

In the past half century, aerospace technology, including the entire world's science and technology, has made great progress, so the original technology and design concepts are no longer suitable for the new multi-purpose orbiter.

So they have to do it all by themselves, and you can imagine how difficult it is.

Thinking of this, Qin Xinghe couldn't help but ask: "Are there any difficulties in the research and development work?"

After hearing Qin Xinghe's words, Wu Hao and Zhang Jun couldn't help but smile silently. After talking so much, they were just waiting for each other's words. Otherwise, he wouldn't have been able to explain it in such detail. Is he such a passionate and diligent person?

have. Wu Hao suppressed his smile and said seriously: "There are many difficulties. It can be said that many of them are things we have not encountered in previous projects."

Haha, I think you are probably waiting for me to speak. Qin Xinghe joked with a smile, and then said angrily: "Don't think that I am so omnipotent. There are many things that I can't do anything about."

Wu Hao heard this and said with a smile: "We also don't want to cause trouble to the leaders, so when we encounter difficulties, we grit our teeth and fight hard, go all out, and continue to work hard with the spirit of not letting go. We believe in sincerity. Even if metal and stone are broken, as long as you work hard enough, even an iron rod can be sharpened..."

"Okay, okay, tell me, what difficulties did you encounter?" Qin Xinghe interrupted Wu Hao repeatedly, and then said angrily.

hehe…

Wu Hao smiled, and then said seriously: "During the development process of this multi-functional orbiter, we encountered many problems, and the most troublesome ones were basic science and material issues, as well as some of the entire multi-purpose orbiter. Difficulties have been encountered in the design of the aerodynamic shape of functional orbiters.

First of all, the biggest problem before us is the design of the aerodynamic shape of this multi-functional orbiter. We know that airflow has a huge impact on the entire aircraft.

Therefore, when designing our multifunctional orbiter, we must consider not only the impact of the airflow on the entire multifunctional orbiter during the ascent stage, but also the impact of the airflow on the entire aircraft body during the descent and gliding stage when returning to the atmosphere.

Especially during the return to the atmosphere and landing stage, the speed is very fast. Although we can simulate it on a computer, this is a computer numerical simulation after all and lacks the support of real data.

Therefore, we hope to apply for a high-speed wind tunnel to conduct tests and help us complete the aerodynamic shape design of this multi-functional orbiter. "

After hearing Wu Hao's words, Qin Xinghe couldn't help but ask: "I remember that you have a better relationship with the military, especially the Air Force. You can definitely ask them for help in this regard. It's not much easier than us."

Wu Hao smiled and shook his head when he heard this and said: "You have to know that when the space shuttle returns to the atmosphere, its speed can reach Mach 24. It has to reduce its speed from Mach 24 to Mach 1 in this dense atmosphere, or even higher. Low, only in this way can it land safely instead of smashing into the ground like a ballistic missile.

Most of the wind tunnels used in the entire aviation system are transonic wind tunnels, with a maximum speed of about two or three Mach, which is completely unable to meet our needs.

So we want to apply for the use of a high-speed wind tunnel, so Smart is looking for you in this regard. "

"You have a good plan." Qin Xinghe cursed with a smile, thought for a moment, and then replied: "I can help you ask whether it is possible or not, and I can't give you a guarantee. You should know that this kind of high-speed wind The cave is an important strategic scientific research facility and is responsible for the development of our country's most cutting-edge and most important strategic equipment and weapons, so we may not be able to spare time for you.

It is even more impossible to get them to stop and give time to you. Everything else must give way to national security, do you understand? "

"I see."

Wu Hao immediately responded: "So please help us ask. It would be best if you can spare time. If not, then we will have to find another way."

"Think of another way. What do you think? Do you have any other options?" Qin Xinghe asked.

Forehead…

Faced with Qin Xinghe's rhetorical question, Wu Hao was really confused. Yes, does he have a second choice? There are only a few high-speed wind tunnels like this in the world. It is an important experimental facility resource at a strategic level. How can it be easily opened to the outside world, let alone the design and development of such a cutting-edge aircraft? Who can allow it.

"Let's do this. You prepare a relevant application document for me and send it over. I'll help you ask and see if it works. If it really doesn't work, then you can only follow me to see the leader." Qin Xinghe After thinking for a while, he said to Wu Hao.

"A major aerospace scientific research project like this, although it is only a civilian project, has a huge role in promoting the development of our country's aerospace technology and should be taken seriously. I believe that the leaders will definitely pay attention to it and support you."

Thank you Bureau Qin. Wu Hao felt happy when he heard this and quickly thanked him. He naturally knew who the leader Qin Xinghe was talking about, so he could make him think about it and take him to see the leader. This shows that Qin Xinghe did not refuse this matter, but attached great importance to and supported this project, otherwise he would not have said such words. After all, who wants to make trouble for himself.

"Don't thank me yet, it's up to you whether the matter will be completed or not." Qin Xinghe's voice came from the phone: "This is just one question, what else is there?"
