A big country of aerospace with black technology

It is not particularly difficult for Zhang Xingyang to finalize the design of the fighter.

In particular, the most important wind tunnel experiment problem has been basically completed under Song Tianxing's previous continuous work.

This also reduced Zhang Xingyang's work to do next a lot.

"Xiao Fu, let everyone take a good rest for a few days."

After a brief exchange with Sun Hongtao, Zhang Xingyang said to Xiao Fu who was still worried about Song Tianxing.

"Dean Zhang, how is my teacher doing now?"

Although Xiao Fu didn't rest all night, he still cared about his mentor's situation first.

Song Tianxing treated him well on weekdays, but after Song Tianxing's accident, Xiao Fu also worried for a long time.

"Mr. Song, his situation has stabilized now."

"Don't worry too much. The medical condition of the Air Force General Hospital is very good, and Mr. Song's follow-up treatment has been arranged."

Zhang Xingyang finally coaxed the worried Xiao Fu away.

"Xing Yang, don't spend too much time on fighter planes now."

Sun Hongtao gave a little reminder:

"You have other important work to do."

"Shenzhou-3 is about to launch, and the preparations for the rocket before launch must not be sloppy."

Shenzhou III is scheduled to launch on November 23rd, and now there are less than three months left.

"I see."

"We have used the Hongyan rocket hundreds of times. The overall system reliability is very high, and there will be no accidents."

Zhang Xingyang was not particularly worried about the rocket system.

After all, in the past few years, there have been several Hongyan rocket launches basically every month.

In the entire system, everyone is very clear about all aspects of the rocket, and where there may be problems, everyone has taken precautions in advance.

What's more, the manned Hongyan rocket has added many measures to ensure the safety of astronauts.

For example, the escape tower, which took a lot of effort to design and manufacture at the Rocket Research Institute, can guarantee the safety of astronauts before and during the launch of the rocket.

"Although it has been launched hundreds of times, for us, manned spaceflight is the first time, and we can't take it too seriously."

Sun Hongtao emphasized the importance of this launch mission.

Manned spaceflight, as the most complex space activity on this planet, involves enormous technological and engineering capabilities. Even after twenty years, the number of countries that can achieve manned spaceflight independently can be counted on one hand. have to come.

As for the independent construction of a manned space station, there is only one country.

Except that China has completed the construction of the Tiangong space station independently.

As strong as Eagle Sauce, it also united more than a dozen countries in the world to complete the construction of the International Space Station.

After 2025, the International Space Station will basically complete its decommissioning work.

Since then, the only space station that has been manned in space is Tiangong.

And behind this is the domestic scientific and technological strength and manufacturing capacity that have been growing for decades.

As the world's number one industrial power, it is able to complete such a space miracle.

As for a country with the largest paper GDP in the world, but has completely hollowed out its industries and almost completely relocated its manufacturing industry, it is almost impossible to complete such a job.

"The Shenzhou-3 rocket, which is specially designed and manufactured for manned spaceflight, has completed the factory work."

Zhang Xingyang also began to talk about the current progress of Shenzhou III to dispel Sun Hongtao's worries.

"It is about to be transported to the Jiuquan Launch Center for pre-launch inspection and preparations."

Domestic manned spaceflight launches are all done by the inland Jiuquan Launch Center, mainly out of safety considerations for launches.

In order to prevent sabotage by hostile foreign forces.

"Tomorrow, the first stage of the rocket will be transported by rail to the Jiuquan Launch Center."

Zhang Xingyang rubbed his drowsy head and said after he hadn't slept all night.

Hongyan rocket is a high-thrust rocket, and its first stage is nearly 50 meters high.

If road transportation is used, it is very difficult to find a vehicle that can carry such a huge object, not to mention the traffic control and various troubles that need to be carried out along the way.

In comparison, the railway train is much more convenient and faster.

In less than two days, the first-stage rocket can be transported from the manufacturing base to the Jiuquan Launch Center.

"The second-level rocket and the escape tower will also be shipped tomorrow, but they will be transported by road."

"All the rocket components are expected to arrive at the rocket assembly plant at the Jiuquan Launch Center in three days."

Zhang Xingyang had already arranged these tasks before.

In fact, he should have been arranging the launch of the rocket at the rocket manufacturing base.

It's just that now it's all delayed by Song Tianxing's sudden illness.

"Since you have all made a schedule, I won't say much."

After Sun Hongtao finished talking about the issue of manned spaceflight, he turned to the issue of astronauts.

"Astronaut training, how is it going now?"

"Are they all ready?"

Although the training of astronauts is not under Zhang Xingyang's control at present, he also knew something about it before.

"The training of the astronauts has been completed, and the first batch of astronauts are all ready to go to the sky."

Although the manned capsule of Shenzhou-3 was designed to carry three astronauts.

However, for safety reasons, the first manned spaceflight will only carry one astronaut.

In this way, even in the worst case, when the rocket has an accident and the escape tower cannot be used, it will not cause greater losses.

As an extremely important part of the three-step process of domestic manned spaceflight, the aerospace system has devoted endless efforts to this launch mission.

We all hope that this launch will be a success.

But as a large-scale system engineering, we have to consider the worst case.

Just as the ancients said: People have no long-term worries, but they must have near-term worries!

"Do you want to go back to Beidu together?"

After talking with Zhang Xingyang and finding that he was not panicked, Sun Hongtao was ready to go back.

After all, he still has a lot of important affairs to deal with, and it is impossible to spend all his time on the wind tunnel base.

However, he still invited Zhang Xingyang along the way.

Because he has to rush back to the rocket manufacturing base today to be responsible for the launch of the manned rocket.

"No, there are still some things to deal with in the base."

Zhang Xingyang shook his head and rejected Sun Hongtao's kindness.

Although Zhang Xingyang arranged for the fighter design team in the base to rest just now.

But the follow-up work arrangements still need to be planned well, it is impossible to keep them in a state of leaderless.

Sun Hongtao's special car crushed the wind and sand on the grassland and left the wind tunnel base.

After watching the other party leave, Zhang Xingyang began to think about how to arrange the design team left by Mr. Song.

But before that, Zhang Xingyang still needs to know more about their current work progress.

Zhang Xingyang's reading speed is comparable to quantum reading, and the upper limit of the speed is mainly limited by the information that the eyes can receive within a unit of time.

Even so, it took Zhang Xingyang nearly an hour to read the current wind tunnel test report of the fighter.

Only after reading the mountain of paper reports and the electronic data of unknown gigabytes.

After reading it, I realized that the wind tunnel experiment of the fighter plane can be regarded as completed.

Because there is only the influence of the fighter tail nozzle on the flight state, and no test has been carried out.

But this part involves the design work of the engine.

If Zhang Xingyang remembers correctly, the Aeronautical Development Research Institute, which is in charge of engine design, has completed the research and development of the WS-10 engine for the stealth fighter.

The full-thrust version of the WS-10 uses a saw-toothed tail nozzle, which can greatly reduce the infrared signature of the engine tail flame and improve the survival rate in air combat.

And it adopts binary vector thrust technology, which can improve a lot of maneuverability.

The thrust has also reached an unprecedented level in China, 178KN.

Two full-thrust versions of the WS-10 can allow the fighter jet to reach a thrust of more than 30 tons without afterburner, and a maximum take-off weight of more than 40 tons.

Zhang Xingyang has finished thinking about the engine. Although he knows that the more advanced WS-15 engine is also under intense research and development, the performance index should be very high, and the development is very difficult. There is no possibility of it being installed within at least five years. .

Therefore, for domestic fourth-generation aircraft that want to complete their first flight as soon as possible, it is basically impossible to count on WS-15.

However, the WS-10 engine can actually be used at this stage.

After learning about the current work progress of the design team, Zhang Xingyang took out a piece of A4 paper from the laboratory desk and began to arrange the next work for them.

Zhang Xingyang did not arrange some extremely difficult tasks for them, but mainly carried out a certain number of wind tunnel experiments.

There are still many places that can be fine-tuned in the current fighter design.

Before Zhang Xingyang was able to free up time to preside over the work of the fighter, they mainly had to do some tinkering work.

Of course, Zhang Xingyang also set a relatively strict work schedule for them.

In order to prevent subsequent work to fall ill.

After finishing the work schedule, Zhang Xingyang took the paper and went to the office building first, and found Qiao Yang who is currently in charge of the life and work of the base part-time.

"After three days, let them work according to this schedule."

Zhang Xingyang said to Qiao Yang patiently.

"Especially the time schedule above, they must be strictly implemented."

After finishing speaking, Zhang Xingyang seemed to think of something:

"correct."

"I will talk to the doctors at the base hospital later today, and plan to organize a base-wide physical examination."

"Everyone must attend."

Qiao Yang looked at Zhang Xingyang with a serious face, so he could understand what he meant.

Obviously, the sudden collapse of Song Tianxing yesterday gave a big warning to everyone in the base.

"I see."

"I'll discuss with them later, the order of medical examination arrangements."

But after finishing speaking, Qiao Yang said seriously:

"Dean Zhang, you also want to participate."

"I?"

Zhang Xingyang's first reaction was to shirk. After all, he had to go back to work at the rocket manufacturing base in the afternoon. It would be a waste of time to have a physical examination at this time.

"Next time, let's talk next time."

"No, if you, the person in charge of the base, can't take the lead to participate, how can we persuade everyone to participate?!"

Qiao Yang's attitude was much more serious, and what he said was not unreasonable.

If Zhang Xingyang, the representative of the base who stayed up late for a long time, did not have a physical examination, then others would have a reason not to participate.

Zhang Xingyang quickly realized the consequences of doing this.

So he said reluctantly:

"Okay, I'll take part."

"But I don't have much time, so arrange it as soon as possible."

Qiao Yang worked very fast. In less than half an hour, he and the doctors confirmed the items to be checked for the physical examination.

And also developed the sequence of physical examination of each department.

An hour later, the physical examination of the whole base officially started.

The first person to undergo the physical examination was Zhang Xingyang, the person in charge of the base.

Although the scale of the base hospital is not very large, after all, it only needs to provide medical services to a few thousand people in the base, but all departments are well-equipped.

Therefore, during the physical examination, there are many items to check.

There are seven or eight items in color Doppler ultrasound, CT, etc. alone.

As for blood routine, urine routine and other laboratory examination subjects, there are more than a dozen items in total.

Even though Zhang Xingyang repeatedly asked to speed up the physical examination, it still took three to four hours to complete such a set of examinations.

However, the examination proved that Zhang Xingyang's body is relatively healthy even with long-term irregular work and rest.

There is nothing wrong with it except that my weight is a bit low because I usually eat too little.

But most of the researchers in the base don't have such good health as Zhang Xingyang.

Because of staying up late for a long time and irregular diet, many people have high blood pressure.

Some researchers who like to relieve stress through overeating also have fatty liver problems.

"Dean Zhang, most of the people in the base have more or less physical problems."

"The serious thing is these few. We found some shadows on their bodies through CT."

The medical examiner handed several physical examination reports in his hand to Zhang Xingyang and said.

Zhang Xingyang originally planned to leave after the physical examination, but he found that the health of the researchers in the base was worse than he thought.

So I postponed my departure for half a day, planning to leave after watching their physical examination.

"You mean, there may be tumors on these people?"

Although Zhang Xingyang doesn't know much about medicine, he also understands what shadow means.

"Can the hospital's equipment detect whether it is a benign tumor or a malignant tumor?"

"Our equipment is not particularly complete. It is best to let them go to a large hospital in Beidu for such an examination."

Zhang Xingyang looked at the report in his hand, thought for a few seconds and said:

"All right!"

"I'll arrange for them to check."

Ask for a monthly pass, ask for a monthly pass! ! !
