The Military-industrial Scientific Research System of the Academic Master Chapter 866

Chapter 866 Installation Targets of Domestic Large Bypass Ratio Turbofans

This time, both Chang Haonan and Luan Wenjie were stunned by Ding Gaoheng's wild ideas.

I can only say that he is a veteran who has participated in the research and development of two bombs and one satellite. He is really good at long-term planning.

When Chang Haonan was first reborn and obtained the system, he did consider things like space exploration, but his idea at that time was nothing more than landing on the moon and Mars, or establishing an outer space orbital space station.

Even later, we even thought about conducting deep space exploration, and after finding a planet where we could land, we would then use technologies such as quantum teleportation to transport equipment, materials, and even living things to the past.

However, farming in outer space is a somewhat simple idea in science fiction...

It is true that it has never happened.

“Not very good.”

"The new generation of medium-sized transport aircraft can also use two high-thrust turbofans instead of four turboprops to achieve a maximum takeoff weight of 80-90 tons and a payload of about 25 tons. This will make the maintenance easier and the flight comfort better. "

During the meeting at the Institute of Geology and Geophysics that day, before he proposed the idea of turning sand into soil, the one that actually attracted most people's attention first was the idea of modifying desert sand and then partially replacing river sand for use in Building materials ideas.

Ding Gaoheng adjusted his sitting posture slightly and assumed a posture of listening attentively.

It is obviously more realistic to modify the covering on the surface of the moon or Mars to make it capable of being used as building materials than to grow food and vegetables in those places.

But after all, Chang Haonan is no longer a member of the Aviation Industry Group, and it is difficult for him to directly direct the work of his brother units.

Chang Haonan shook his head:

“But there are still some things related to the aviation development group's business. I originally planned to report to you at the end of the year, but I'm here today...”

After a short pause, he continued:

In fact, the clarity of images observed by near-Earth space instruments such as the Hubble Telescope is generally quite poor, and there is only a single optical channel, which is simply not enough to provide data for in-depth analysis.

But after 2010, it will basically become the preferred object of all countries around the world.

Chang Haonan thought seriously for a while, and then said:

　　While Luan Wenjie finished speaking, Chang Haonan intervened in time:

“I remember Director Luan mentioned in a previous meeting that the space agency is planning to carry out a lunar exploration project?”

To reduce the dimensionality of high-dimensional data, you must first have high-dimensional data.

The latter immediately started making tea.

“But having said that, maybe some moss or fungi and the like are not without possibility of survival?”

So, this is for my own project.

Furthermore, mainline passenger aircraft also involve airworthiness certification issues.

"The possibility is very small. Although there are indeed some anaerobic plants or microorganisms, they cannot survive under any circumstances. For example, the oxygen content in the Martian atmosphere is less than 1% and carbon dioxide is more than 98%. Even if it is really like It is currently widely speculated that there is a certain amount of liquid water, but the environment is still too bad anyway. It would be better to have an Earth-like planet..."

“Like the three new models you mentioned last year when the Aerospace Power Group was established?”

"Xiao Chang, are you here just for space breeding?" Ding Gaoheng took the tea cup from Chang Haonan and asked with a smile.

Although extraterrestrial exploration is more realistic than landing on extraterrestrial planets, it must first be able to go to deep space.

Especially for the international aviation market, China is still a new player.

“Anyway, when our large bypass ratio turbofan is developed, C909 should also be domestically produced.”

After watching Luan Wenjie leave the office, Ding Gaoheng himself left the office chair and sat on the sofa next to Chang Haonan.

It does not mean that aviation development development should be disconnected from aircraft models.

Luan Wenjie, who was next to him, actually shook his head and said matter-of-factly:

“Having said all that, no matter what we plan to do, we still have to go to outer space first.”

This time, Ding Gaoheng understood clearly—

The conversation continued for about twenty minutes, until Luan Wenjie raised his wrist to look at the time and said that he had a meeting to hold later, and the conversation ended.

but.

“The C909 was designed to adapt to the PS90A, which has a relatively small diameter. Changing to a larger size aircraft engine will cause safety risks.”

Chang Haonan did not speak, but just listened to Luan Wenjie's first thoughts, and then entered into his own thinking—

“Yes, you remember correctly.”

Listening to Chang Haonan's answer, Ding Gaoheng gradually became happy.

Exploration, sampling, analysis.

At this moment, China is still working hard to achieve the first manned space flight. Let alone extraterrestrial planets, even the lunar exploration project has not been officially approved. It is indeed a bit early to consider what will happen after landing on extraterrestrial planets. .

But now, it's completely different.

So this topic comes to an end.

“Hiss…it seems to be the same…”

After coughing twice, Chang Haonan and Luan Wenjie's attention was finally attracted again:

“Actually, I just thought about it casually, you don't need to take it so seriously…”

It's just that this time Chang Haonan talked to Ding Gaoheng.

Although the matter of space farming is still relatively far away, Ding Gaoheng's imagination just now has brought a lot of inspiration.

In short, military aircraft have less worries.

Those beautiful alien photos that people usually see on the Internet or in books and magazines are actually a lot of secondary renderings.

“On the one hand, it is for self-use, and it can also compete with the alternatives of An-12 and C130 in the international market. On the other hand, it can also accumulate some experience for the research and development of future 80-ton mainline passenger aircraft.”

The Netherlands, Hungary, Portugal, South Korea, and even the US Air Force are all very fond of this model.

"At this moment, the design of the Turbofan 10 is about to be finalized. Although there will still be production and finalization tasks in the future, the manpower required is much less than now, especially when other factories are sent to Shengjing to participate in the Turbofan 10 The comrades on the project will be able to return to their original units before the Spring Festival next year at the latest, so that they can take on some new projects..."

In the past, his biggest headache was hearing about new projects related to aviation development.

After a brief silence, Luan Wenjie broke the silence first:

“Compared to transforming alien planets, the technology developed by Mr. Chang seems to be more suitable for exploring alien planets. At least it allows us to obtain more detailed surface information of the target from a relatively long distance...”

“So the intention of our superiors is to wait until our automatic control soft landing technology has passed more tests before officially launching the lunar exploration project..."

And I heard that the project application process is already underway.

Chang Haonan didn't know much about aerospace in his previous life, so he specifically brought the topic in this direction. Sure enough, he heard a lot of things from Ding Gaoheng and Luan Wenjie that he didn't know much about before.

He nodded first:

“Ahem—”

For example, the KC390 developed by Embraer has almost become the first choice among aircraft of the same class in the 2020s.

"The first naval gas turbine, which I have contacted with Institute 701 before, is prepared for future domestically produced main surface ships. The third turboshaft engine... We still have relatively few technical reserves in the turboshaft aspect. In addition, there are not many people sent by Southern Dynamics, and their capabilities are relatively weak, but they are not that fast. "

Ding Gaoheng asked:

“I remember that there seems to be a high-power aeroderivative gas turbine, a large bypass ratio turbofan engine, and a... 1600kw-class turboshaft?”

"In the long run, we will definitely design a new passenger aircraft of the same level as the Airbus A320 or Boeing 737 from scratch. However, Hufei's research and development capabilities are currently relatively average, and almost all of its efforts are used in the localization of the two models. Above, I am afraid there will be no extra energy in a short period of time, and the new passenger aircraft is equipped with a new engine, which may inevitably cause concerns for the airlines. "

"Technically speaking, launching a satellite to orbit the moon, including achieving a hard landing on the moon, is basically not difficult for us. What is more challenging is the soft landing, and later the return to the earth. ”

Once an engine is built, it must be installed on an airplane to be considered a real success.

And if you want to verify the feasibility of this road, the first step you have to do is actually no different from what it is on earth.

The aviation field is different from most other fields. The requirements for reliability, maintenance hours, and safety of civilian aircraft are much more stringent than those of military aircraft.

The two sang and coordinated so seamlessly that it actually made Ding Gaoheng, who first proposed the idea, a little helpless:

This idea of using twin turbofans to replace four turboprops would have been relatively rare in 2000.

“So I thought it would be better to let this model stand the test on military aircraft for a period of time.”

Chang Haonan frowned slightly:

“It's already an Earth-like planet, so there's a high probability that it already has soil similar to the Earth's, so why bother transforming it…”

“Actually, what I really want to say…”

Ding Gaoheng thought:

“But strategic transport aircraft like the IL-76 or C17 may not be available in the short term..."

“That's what happened.”

“You can make it smaller.”

And Luan Wenjie had said so much in meetings that he usually held, how could he remember such details? He only thought that he had mentioned it during an internal meeting.

“Can't it be directly replaced with C909?”

In fact, he had never heard of it at all. He only vaguely remembered that the lunar exploration project in the previous life was probably established in the past few years.

So actually...

Of course, Chang Haonan himself has no idea of strengthening his career in the construction industry for the time being.

“Mainly for breeding purposes.”

“Military aircraft that use large bypass ratio turbofans...basically only military transport aircraft.”

“Comrade Wenjie and Comrade Ye Jianpei, the chief engineer of the Ziyu-2 satellite, have reported to the higher authorities twice through me.”

"Like Mars, the situation is relatively stable, and the main surface is sand and gravel. It can't be said that there is no hope at all... But for some planets with harsh environments, even solid or gaseous... then there is definitely no hope, and there are also involved Plants cannot grow without soil, they also need water and oxygen..."

In other words, a return detector must be launched.

Chang Haonan affirmed:

However, Chang Haonan just thought of something else.

So the latter answered directly:

“This is just the second project. The large bypass ratio turbofan... still needs to find a suitable installation target.”

But if we promote it...

Ding Gaoheng asked:

Chang Haonan said the plan he had thought of for a long time:

“Our level of structural design and aviation materials is not yet sufficient to support the development of a 200-ton transport aircraft, but those using turbofans do not necessarily have to be heavy-duty transport aircraft.”

Although Huaxia's products are unlikely to be sold in the United States, other markets can still compete.

But since the leader asked specifically, Chang Haonan definitely couldn't answer so straightforwardly.

The aero-engine project was established independently of the aircraft model, but it just got rid of its past vassal status.

In short, these can only be regarded as reserved ideas.

Indeed.

“That depends on the specific conditions of the outer planet.”

He just said it casually at first, but later he actually analyzed it logically.

Although the few people just talked about a lot, the ocean surveillance satellites and lunar exploration were purely coincidences caused by Luan Wenjie's presence here.

After all, even Rafale's engines use Chinese technology.

The sensitivity of transport aircraft is still much lower than that of main battle equipment...
