The design of the wave-riding body configuration of medium- and short-range ballistic missiles is all new technology.

This technical route has never been taken by anyone before.

Even successful cases could not be found, so the technology developed in the early stage was slow.

The most difficult part was the design of the aerodynamic layout.

Although the YF-21 hypersonic wind tunnel assists, the design team has excellent conditions that no other hypersonic weapon design team in the world has.

But it's still a little more difficult than previously thought.

Several of the proposals proposed by the team did not achieve the desired effect.

Originally, the advantage of the waverider configuration is that it has a high lift-to-drag ratio, which can greatly increase the range of the missile, and the maneuverability in the middle of the missile is very high.

However, the missile shape scheme designed by everyone now always fails to meet the indicators of the previous theoretical calculations.

"Is it only possible to carry out wind tunnel experiments and make adjustments little by little?"

Qiao Yang held the latest wind tunnel data and said a little unwillingly.

Wind tunnel testing has been going on for almost a month.

However, it was only tested that the configuration they had designed before was not up to Mach 10 or more in theory.

It can only reach Mach 8 at most, and at this speed, there will be all kinds of instability.

"The current situation is still expected."

Zhang Xingyang was not too angry, after all, scientific research work was not smooth sailing.

A wide variety of problems can arise at any time.

"At the very least, we've verified that this path really works."

"It's a big catch!"

This is indeed a great success, and sometimes scientific research work is not afraid of anything, but is afraid of the wrong route.

If it is a truth that cannot be followed, then the deeper you go, the greater the loss in the end.

However, the issue of scientific research direction is not a problem in Zhang Xingyang's eyes.

After all, with more than 100 years of forward-looking vision, he can avoid many possible risks.

"But isn't it too much to keep experimenting like this?"

Qiao Yang was a little worried, after all, the YF-21 shock wave wind tunnel needs to consume tens of thousands of yuan just to start once.

And that's not even counting the cost of equipment wear and tear in a shock wave wind tunnel.

All of them add up, an experiment that lasts less than a second will cost tens of thousands of yuan!

In the past month, they have done at least hundreds of experiments in order to verify the shape and aerodynamic scheme of the missile!

In other words, in a month, it took almost tens of millions!

However, this money can only be regarded as a drop in the bucket compared to the tens of billions spent in the construction process of the wind tunnel!

And compared to the output of the wind tunnel, the investment is also worth it.

"Don't worry about money."

"The experimental funds for this project are sufficient, don't worry!"

Zhang Xingyang swore and made his own guarantees.

In fact, tens of millions of experimental funds per month are not a lot for such a large experimental base.

Of course, the reason why Zhang Xingyang has such self-confidence is mainly because of the overseas asset development plan presided over by Zhou Zhengxiong before, which has made a lot of gains in the past two years.

As part of the beneficiary's wind tunnel experimental base, it has also received a lot of funds from here.

Therefore, even if the state does not allocate funds, relying on this part of the income alone, it is not a problem for the wind tunnel test base to maintain its own operation.

"If you want a good configuration, you still have to do more experiments!"

"If the wind tunnel blows enough, it will definitely be able to come out with the strongest configuration!"

Zhang Xingyang cheered Qiao Yang up.

After all, on the side of the wind tunnel base, Qiao Yang is responsible for the main aerodynamic shape modification work.

Zhang Xingyang has many projects that need to be responsible, whether it is a low-orbit satellite communication project or a manned space project, he needs to participate.

The time available for hypersonic missiles is really limited.

"Now the use time of the wind tunnel is basically used to the limit."

Qiao Yang said helplessly.

People can work in two or three shifts.

However, the equipment is not good, and it needs to be carefully checked after each experiment.

Otherwise, if there is any accident for such a big guy, the loss will be calculated according to 100 million yuan.

No one can afford to take such responsibility.

"Unless we can build another tunnel like this, it's going to be very difficult to improve work efficiency."

"Impossible!"

"These wind tunnels were all built with great difficulty."

"The construction cost alone is more than 10 billion."

Zhang Xingyang directly interrupted Qiao Yang's whimsical thoughts.

"If we build it again, we will also build a higher-level wind tunnel with a test speed of more than 20 times the speed of sound."

"It's hard to say whether a wind tunnel like this will be built in 10 years."

A wind tunnel with more than 20 times the speed of sound, which is basically used to verify the aerospace fighter, that is, the new standard sixth-generation aircraft.

In this era when the fifth-generation aircraft has not yet been completed, it is a more advanced concept, so it is basically impossible to build it within ten years.

"Of course I know that it's not easy to build another one." Qiao Yang said.

"I don't want to work faster in R&D."

Although it took a month to complete the verification of the technical route, it can be regarded as very fast.

But Qiao Yang still wants the research and development work to be faster.

Because at this time, we need all kinds of weapons to defend our increasingly severe national defense security.

The wave-riding ballistic missiles are mainly intended to replace the DF-11 and DF-15 short-range ballistic missiles, which are already slightly outdated.

"If you have time, you can improve your current aerodynamic calculation model."

After Zhang Xingyang finished reading all the experimental records, he said to Qiao Yang.

"Didn't the Academy of Sciences get you a supercomputer?"

"It'll be here next week."

"If there is anything missing, make a report, and I will approve it for you."

Although the wind tunnel experimental base is located on a desolate plateau, the living conditions of the experimenters are not bad at all.

In this era of general lack of various grains, oils and non-staple foods, meat can be eaten basically every day, and even some seafood can be eaten during holidays.

You must know that the nearest sea here is also a distance of thousands of kilometers.

All the supplies for the base were brought in by rail from somewhere else.

"In terms of food, there is not much shortage."

Qiao Yang didn't hesitate and directly began to make requests.

"But in terms of warm clothing, it's really a little short."

As the person in charge of the aerodynamics of the missile, Qiao Yang has a better understanding of the situation in the wind tunnel base.

"Isn't there heating everywhere in the base?"

Zhang Xingyang was a little puzzled, after all, there was a thermal power plant in the base that was almost non-stop day and night.

The plant produces huge amounts of hot water at all times, and it was designed with reuse in mind.

Therefore, there is heating everywhere in the entire base, and even the small garden in the base is heated, and you can still see all kinds of plants blooming.

"The cold wind on the plateau is far stronger than when we were in the south."

"When it's windy, it's better indoors, but the outdoor heating spots are useless."

Thinking of those days, Qiao Yang still feels a little incredible.

In fact, on the plateau, this is the case all year round, and winter comes early.

It's only September, and it's only August in the lunar calendar.

The first snow has already fallen on the plateau!

Hu Tian is snowing in August, and the ancients do not deceive me!

"Okay, I'll get them to send a batch of warm supplies as soon as possible."

Zhang Xingyang kept this incident in mind.

"Is there anything else missing?"

"It's gone."

After Qiao Yang finished answering, he remembered something.

"Oh, yes."

"Can you get us some of the latest issues?"

This request was a bit unexpected by Zhang Xingyang.

After all, the journals in this world are very old content in his eyes.

However, this is only his own opinion, in fact, for others, if they want to understand the cutting-edge research content, they still have to rely on these journals.

"Okay, what do you need?"

Since the other party made such a request, Zhang Xingyang still tried his best to meet the other party.

"Write me an entry, and I'll have someone send it to you every month."

The wind tunnel experimental base is said to be hard, but it is also hard, after all, the location is on the plateau with relatively poor natural conditions.

However, their conditions are still much better than those of others who also work on the plateau.

All kinds of materials, once there is a little shortage, can be delivered in less than a week.

——

Beidu, a nondescript suburban courtyard.

The garden is overgrown with a variety of plants.

An old man with gray hair was patiently tending to the bonsai pine in front of him.

"Luo Lao!"

Zhang Xingyang pushed open the door of the small courtyard and walked in.

"I brought you a little present."

As he spoke, Zhang Xingyang stretched out the two big boxes in his hands.

"Come on, come on, what kind of gifts to bring!"

As a soldier who has experienced the major wars before and after the founding of the People's Republic of China, Luo Lao is very disgusted with gift-giving.

"Luo Lao, you absolutely like this thing!"

Zhang Xingyang didn't know Luo Lao's performance, but he still brought things over.

Just knowing this gift, Luo Lao will definitely not refuse.

Zhang Xingyang cautiously opened one of the boxes.

It was an extremely elaborate model of the rocket, and you could even see the miniature manned space logo on it.

"How did you do this?"

As soon as Luo Lao saw the contents of the gift box, his eyes couldn't take his eyes off.

As a person who dedicated the rest of his life to the aerospace industry, Luo Lao really has no resistance to such a gift.

"Isn't this an encouragement for the development of space tourism?"

"This is their latest product from the Xichang Launch Base."

"The Hongyan modified rocket model of Shenzhou-1 was launched!"

"Not bad, not bad."

Luo Lao held the rocket with a height of fifty or sixty centimeters, and praised with a happy smile.

"Is this your own processing plant?"

"It feels good!"

"Indeed, in fact, everything here is miniature in equal proportions."

Zhang Xingyang pointed at the rocket and said:

"Of course, there are only four or five such scale-scale models."

"I just thought I'd send you one."

Luo Lao seemed to have never seen such a delicate rocket model, and he looked up and down for a long time before he reacted.

I should have invited Zhang Xingyang into the house to sit down.

"Come in and sit down, and I'll pour you some tea."

After entering the house, Luo Lao took out a tea jar from the cabinet in the hall and began to prepare to make tea.

Luo's hometown, Zhang Xingyang is also the first time to come.

However, he also knew before that Luo Lao's wife left early, and his son worked in the south, so he was the only one in the family.

So the two of them were also able to talk about something that involved confidential content.

Luo Lao took out two large porcelain cups with a sense of age and poured a full cup of tea.

"The Longjing tea sent by my son from the south, I drink it well, you can taste it."

Luo Lao was in a good mood at this time, and the whole person smiled like Maitreya Buddha.

Zhang Xingyang took a sip, it was really good.

Smooth in the mouth and sweet in the aftertaste.

"Good tea!"

"I heard you've done a lot of great things lately?"

Luo Lao's news is still very well-informed, although he is now mainly responsible for the aerospace field, but his former comrades-in-arms are everywhere.

"What are you talking about?"

He has done a lot of things in the past two years, and Zhang Xingyang doesn't know which aspect Luo Lao is referring to.

"The navy was going to send you a pennant some time ago!"

After Luo Lao took a sip of tea, he smiled and said:

"The explosives you've made are so perverted."

As soon as Luo Lao said this, Zhang Xingyang also knew what the other party was talking about.

The ship-borne 300 mm rocket artillery is extremely ferocious in both ground and ship strikes.

The advent of all-nitrogen explosives means that the power of the original charge of hundreds of kilograms can be achieved by only a few kilograms in the future.

It can be said that it has changed the face of future warfare to some extent.

"Luckily, I made it up in the lab."

Zhang Xingyang casually found an excuse, after all, the appearance of this thing cannot be investigated.

Luo Lao also knew that Zhang Xingyang was definitely unwilling to say it in detail, so he didn't care too much about him making excuses to perfunctory himself.

"It's a pity that the range is still not far enough, if only it were farther."

Luo Lao sighed with some nonchalantness.

"You can't cover the whole area of the footbasin!"

As an old man who survived that war, Luo Lao has an unimaginable hatred for the footbasin.

After all, his parents and brothers all died in that war.

"After all, the 300-mm rocket platform is a little bit bigger, and it is already the limit to be able to do 600 kilometers."

Zhang Xingyang can also understand Luo Lao's mood a little.

"But if it's a bigger platform, it's not that hard to do that!"

Although Zhang Xingyang said very vaguely, Luo Lao vaguely heard what he meant.

"Do you have a new research plan?"

"I just don't know if I still have a chance to see that day!"

Luo Lao is now almost ninety years old, and as his life is coming to an end, he has been thinking about it a little bit.

"There will be a chance, Luo Lao." Zhang Xingyang said.

The new waverider configuration medium-range ballistic missile has a design range of up to 4,000 kilometers.

Enough to complete the blow to any part of the whole territory of the foot basin.

Even Guam in the Pacific Ocean is within its deterrent range!
