A big country of aerospace with black technology

The short-range ballistic missiles in the waverider configuration are all new technologies in design.

This technical route has never been taken before.

Even successful cases cannot be found, so the technology developed in the early stage is very slow.

The most difficult thing is the design of the shape and aerodynamic layout.

Although the YF-21 hypersonic wind tunnel is assisted, the design team has excellent conditions that other hypersonic weapon design teams in the world do not have.

But the difficulty is still greater than previously imagined.

Several proposals proposed by the team failed to achieve the expected results.

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 has high maneuverability in the middle of the missile.

However, the shape schemes of the missiles that everyone designs now cannot always meet the indicators of the previous theoretical calculations.

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

Holding the latest wind tunnel data, Qiao Yang said unwillingly.

Wind tunnel tests have been going on for almost a month.

However, only the configuration they designed before was tested, which could not reach the theoretical Mach 10 or above.

It can only reach Mach 8 at most, and at this speed, various instability situations will appear.

"The current situation is still expected."

Zhang Xingyang was not too angry, after all, scientific research work was never smooth sailing.

All kinds of problems can arise at any time.

"At the very least, we have verified that this road can really work."

"It can be regarded as a big gain!"

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

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

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

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

"But this kind of non-stop experimentation, isn't it consuming too much experiment funds?"

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

This is not counting the loss of various equipment in the shock tunnel.

Adding it all up, an experiment that lasts less than one second costs tens of thousands of yuan!

In this nearly a 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 one month, almost tens of millions were spent!

However, compared with the tens of billions spent on the construction of the wind tunnel, this money is only a drop in the bucket!

And compared to the output of the wind tunnel, such an investment is worthwhile.

"Don't worry about money."

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

Zhang Xingyang vowed to make his own promise.

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

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

As a partial beneficiary, the wind tunnel experiment base also received a lot of funds from here.

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

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

"The wind tunnel blows enough, and the strongest configuration will definitely come out!"

Zhang Xingyang encouraged Qiao Yang.

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

There are many projects that Zhang Xingyang needs to be responsible for, whether it is a low-orbit satellite communication project or a manned spaceflight project, he needs to participate.

The time that can be allocated to hypersonic missiles is really limited.

"The use time of the wind tunnel is basically used to the limit by everyone."

Qiao Yang said helplessly.

People can work in two or three shifts.

But the equipment is not good, and careful inspection is required after each experiment.

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

No one can afford such a responsibility.

"Unless we can build another wind tunnel like this, it will be difficult to improve work efficiency."

"impossible!"

"These wind tunnels were built with great difficulty."

"The construction cost alone exceeded 10 billion."

Zhang Xingyang directly interrupted Qiao Yang's whimsical thoughts.

"The further construction is to build a higher-level wind tunnel with a test speed exceeding 20 times the speed of sound."

"It's hard to say whether a wind tunnel like this can be built within ten years."

Wind tunnels with a speed of more than 20 times the speed of sound are basically used to verify aerospace fighters, that is, the new standard sixth-generation aircraft.

In this era when the fifth-generation machine 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 also know that building another one is not an easy task." Qiao Yang said.

"It's not that I also want the research and development work to be faster."

Although the verification of the technical route was completed in one month, it can be regarded as very fast.

But Qiao Yang still wanted to speed up the research and development work.

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

The waverider ballistic missile is mainly to replace the Dongfeng-11 and Dongfeng-15 short-range ballistic missiles that are already slightly behind.

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

Zhang Xingyang said to Qiao Yang after reading all the experimental records.

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

"It will be delivered next week."

"Is there anything missing? Make a report and I'll approve it for you."

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

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

You must know that there are thousands of kilometers away from the nearest sea.

All the supplies of the base are transported from other places by railway.

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

Qiao Yang didn't hesitate at all, and directly started making requests.

"However, in terms of warm clothes, there is indeed a part of the gap."

As the person in charge of missile aerodynamics, Qiao Yang has a better understanding of the situation at 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 around the clock.

The power plant produces a huge amount of hot water every moment, and the issue of reuse was also considered at the beginning of the design.

Therefore, heating is basically everywhere in the entire base, and even the small garden in the base has heating, and now you can still see various plants in bloom.

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

"When the wind blows, it's better indoors, and the heating points outside are useless at all."

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

In fact, on the plateau, this is the case all year round, and winter comes very 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, the ancients do not deceive me!

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

Zhang Xingyang kept this matter in his heart.

"Apart from these, is there anything else that is lacking?"

"Gone."

After Qiao Yang answered, he remembered something again.

"Oh, right."

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

This request was a bit beyond Zhang Xingyang's expectation.

After all, the periodicals in this world are very old-fashioned in his eyes.

But this is just his own opinion. In fact, for other people, they still rely on these journals if they want to understand the cutting-edge research content.

"Okay, what kind of content do you need?"

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

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

The wind tunnel experiment base is said to be difficult, but it is also difficult. After all, it is located on a plateau with relatively poor natural conditions.

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

All kinds of materials, once there is a little gap, can be delivered within a week.

——

Beidu, an inconspicuous suburban courtyard.

The yard is full of various plants.

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

"Old Luo!"

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

"I brought you a little present."

As he spoke, Zhang Xingyang stretched out the two large boxes in his hand.

"Come on, come on, and bring any gifts!"

Luo Lao, as a soldier who has experienced various wars before and after the founding of the People's Republic of China, is very disgusted with the practice of giving gifts.

"Old Luo, you absolutely love this thing!"

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

Just knowing this gift, Mr. Luo would never refuse it.

Zhang Xingyang carefully opened one of the boxes.

It was an extremely exquisite rocket model, and even the miniature manned spaceflight logo could be seen on it.

"This thing, how do you do it?"

As soon as Mr. Luo saw what was in the gift box, he couldn't move his eyes away.

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

"Isn't this encouraging the development of space tourism?"

"This is the latest product they launched at the Xichang launch base."

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

"Not bad."

Luo Lao held the rocket with a height of 50 to 60 centimeters, and praised it with a cheerful smile.

"Is this made by your own processing factory?"

"It feels like a good workmanship!"

"Indeed, in fact, everything here is scaled down."

Zhang Xingyang pointed to the rocket and said:

"Of course, I only made four or five such scale models."

"I just wanted to give you one."

Luo Lao seemed to have never seen such an exquisite rocket model before. He looked up and down for a long time before he realized it.

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

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

After entering the room, Mr. Luo took out a tea pot from the cabinet in the main room and began to prepare tea.

Zhang Xingyang also came to Luo's hometown for the first time.

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

So two people can also chat about things that involve confidential content.

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

"The Longjing tea sent by my son from the south is not bad for me. Try it."

Mr. Luo was in a good mood at this time, smiling like Maitreya Buddha.

Zhang Xingyang took a sip, and it was really good.

The entrance is smooth and the aftertaste is sweet.

"Good tea!"

"I heard that you have done a lot of great things recently?"

Old Luo's news is still very well-informed. Although he is mainly in charge of the aerospace field now, his former comrades-in-arms are everywhere.

"Which aspect are you talking about?"

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

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

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

"The explosives you made are too perverted."

When Mr. Luo said this, Zhang Xingyang also knew what the other party was talking about.

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

The birth of nitrogen explosive means that the power of hundreds of kilograms of explosives can be achieved in the future with only a few kilograms.

It can be said that it has changed the appearance of future wars to some extent.

"Good luck, it was made out of messing around in the laboratory."

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

Luo Lao also knew that Zhang Xingyang would definitely not want to go into details, so he didn't care too much about him making excuses to perfuse himself.

"It's a pity that the shooting range is still not far enough. It would be nice if it was farther."

Luo Lao said with a little carelessness.

"It cannot cover the whole area of ​​the foot basin!"

As an old man who survived that war, Mr. Luo has an unimaginable hatred for the foot basin.

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

"After all, the 300mm rocket platform is only a little bit big, and it is already the limit to reach 600 kilometers."

Zhang Xingyang also somewhat understood Luo Lao's mood.

"However, if it is a larger platform, it is not so difficult to do this!"

Although what Zhang Xingyang said was vague, Mr. Luo vaguely heard what he meant.

"Do you have a new research plan?"

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

Mr. Luo is almost ninety years old now, and as his life draws to a close, that's all he thinks about.

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

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

It is enough to complete the blow to any place in the whole territory of the foot basin.

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