Chapter 866 Installation targets of domestic large bypass ratio turbofans
This time, Chang Haonan and Luan Wenjie were both stunned by Ding Gaoheng's wild ideas.
It can only be said that he is a veteran who has participated in the development of two bombs and one satellite. He really has something in the long-term planning.
When Chang Haonan was reborn and obtained the system, he did consider space exploration and the like, but his idea at that time was nothing more than landing on the moon and Mars, or establishing an outer space orbital space station.
I even thought about conducting deep space exploration later, and after finding a planet where I could land, I 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 indeed unprecedented.
"That depends on the specific conditions of the alien planet."
Chang Haonan thought seriously for a while, and then said:
"Like Mars The situation is relatively stable, and the main body of the surface is sand and gravel. It cannot be said that there is no hope at all... But for some planets with harsh environments, even solid or gaseous planets... it is definitely hopeless, and there are also plants involved here. It can grow on soil, and it also needs water and oxygen..."
"But having said that, maybe some things like moss or fungi have no possibility of survival?"
He just said it casually at first, but later he actually analyzed it logically. .
Luan Wenjie, who was next to him, actually shook his head and said matter-of-factly:
"The possibility is very small. Although there are indeed some anaerobic plants or microorganisms, it is not possible under any circumstances. All can survive. For example, the oxygen content in the Martian atmosphere is less than 1% and carbon dioxide is more than 98%. Even if there is a certain amount of liquid water as currently widely speculated, the environment is still too bad. It is best to have some An Earth-like planet..."
Chang Haonan frowned slightly:
"It's already an Earth-like planet, so there's a high probability that it has soil similar to the Earth's. Why bother transforming it..."
"Hiss...it seems to be the same..."
The two of them sang and cooperated perfectly, which made Ding Gaoheng, who first proposed the idea, a little helpless:
“Ahem——”
After coughing twice, Chang Hao was finally Nan and Luan Wenjie's attention was attracted again:
"Actually, I just thought about it casually. You don't need to take it so seriously..."
At this moment, China is still working hard to achieve the first manned space flight, let alone extraterrestrial planets, and even the lunar exploration project The project has not yet been officially approved. It is indeed a bit early to consider what happens after landing on alien planets.
So this topic comes to an end.
However.
Although the matter of farming in space is still relatively far away, Ding Gaoheng’s imagination just now brought a lot of inspiration.
"Actually, if I really want to say..."
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. The planet can at least allow us to obtain more detailed surface information of the target from a relatively long distance..."
Chang Haonan did not speak, but just listened to the thoughts Luan Wenjie first described, and then Entering into my own thoughts——
Although extraterrestrial exploration is more realistic than landing on extraterrestrial planets, it must first be able to go to deep space.
The beautiful alien photos that people usually see on the Internet or in books and magazines are actually a lot of secondary renderings.
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 not enough to provide data for in-depth analysis.
To reduce the dimensionality of high-dimensional data, first you must have high-dimensional data.
In short, these can only be regarded as reserved ideas.
However, Chang Haonan just thought of something else.
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.
And I heard that the project application process is already underway.
Of course, Chang Haonan himself has no idea of strengthening his career in the construction industry for the time being.
But if it is promoted...
Modifying the covering on the surface of the moon or Mars to make it capable of being used as a building material is obviously better than growing food seeds in that place. The dishes are much more realistic.
And if you want to verify the feasibility of this road, the first step you need to do is actually no different from what it is on earth.
Exploration, sampling, analysis.
In other words, a return detector must be launched.
“Having said so much, no matter what we plan to do, we still have to go to outer space first.”
While Luan Wenjie finished speaking, Chang Haonan jumped in in time:< br>
"I remember Director Luan mentioned in a meeting before that the space agency is planning to carry out a lunar exploration project?"
In fact, he had never heard of it at all, but vaguely remembered the lunar exploration project in his previous life. The project was probably established in the past few years.
And Luan Wenjie said so much in meetings that he usually held, how could he possibly remember such details? He only thought that he mentioned it during an internal meeting.
However, this time Chang Haonan talked to Ding Gaoheng.
So the latter answered directly:
"That's what happened."
"Comrade Wenjie and Comrade Ye Jianpei, the chief engineer of the Ziyu-2 satellite, have reported to the higher authorities twice through me."
< br>"Technically speaking, launching a satellite to orbit the moon, including achieving a hard landing on the lunar surface, is basically not difficult for us. What is more challenging is the soft landing, and what is beyond Return to Earth.”
“So the superior’s intention is to wait until our automatic control soft landing technology has passed more tests before officially launching the lunar exploration project...”
Chang Haonan’s previous life to I didn't know much about aerospace, so I specifically brought the topic in this direction. As expected, I heard a lot of things from Ding Gaoheng and Luan Wenjie that I didn't know much about before.
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.
After watching Luan Wenjie leave the office, Ding Gaoheng himself left the office chair and sat on the sofa next to Chang Haonan.
The latter immediately started making tea.
"Xiao Chang, are you here just for space breeding?" Ding Gaoheng took the tea cup from Chang Haonan and asked with a smile.
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.
So actually...
It is indeed.
But since the leader asked specifically, Chang Haonan definitely couldn't answer so straightforwardly.
He nodded first:
"The main reason is indeed for breeding."
After a short pause, he continued:
"But there are still some situations related to the business of the Hangfa Group. I originally planned to report to you at the end of the year. Yes, but I have come today..."
Ding Gaoheng adjusted his sitting posture slightly and assumed a posture of listening attentively.
“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 dispatched. The comrades who participated in the Turbofan 10 project in Shengjing 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..."
Listening to Chang Haonan's answer, Ding Gaoheng gradually became happy.
In the past, his biggest headache was hearing about new projects related to aviation development.
But now, it is completely different.
“Like the three new models you mentioned last year when the Aviation Power Group was established?”
Ding Gaoheng asked:
"I remember that there seemed to be a high-power aeroderivative gas turbine, a high-bypass ratio turbofan engine, and... a 1600kw-class turboshaft?"
"Yes, you remember it correctly."
Chang Haonan affirmed:
"The first ship-use gas turbine, I have contacted with the 701 Institute before, is prepared for the future domestically produced main surface ships. The third A turboshaft engine... Our technical reserves in the turboshaft aspect are still relatively small, and Southern Power has not sent many people, so our capabilities are relatively weak, but it is not that fast.”
"It's just this second project, the large bypass ratio turbofan... we still have to find a suitable installation target."
At this time, Ding Gaoheng understood clearly -
The aerospace engine project was independent of the aircraft model, but it just got rid of its past vassal status.
This does not mean that aviation development development should be disconnected from aircraft models.
Once an engine is built, it must be installed on an airplane to be considered a real success.
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.
So, this is for my own project.
“Can’t it be directly replaced with C909?”
Ding Gaoheng asked:
“Anyway, when our large bypass ratio turbofan is developed, C909 should also be able to complete it. It’s localized.”
“Not good.”
Chang Haonan shook his head:
“When the C909 was designed, it was adapted to the PS90A, which has a relatively smaller diameter. Changing it to a larger size aircraft engine will cause safety risks.”
“ 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 R&D capabilities are currently relatively average, and almost all of its efforts are used in the localization of the two models. , I am afraid that there will be no extra energy in a short period of time, and the brand-new passenger aircraft is equipped with a new engine, which may inevitably cause concerns for the airlines.”
“So I considered letting this model endure a period of time on military aircraft. The test of time. ”
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.
Especially for the international aviation market, China is still a new player.
Furthermore, mainline passenger aircraft also involve airworthiness certification issues.
In short, military aircraft have less worries.
"Military aircraft that use large bypass ratio turbofans... basically only military transport aircraft."
Ding Gaoheng thought:
"But strategic transport aircraft like the IL-76 or C17 may not be available in the short term..."
"We can build a smaller one."
Chang Haonan said. A plan that has been thought of for a long time:
“Our level of structural design and aviation materials is not yet enough to support the research and development of a 200-ton transport aircraft, but those using turbofans do not necessarily have to be heavy-duty transport aircraft. "
"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 load capacity of about 25 tons, which will make it easy to maintain and fly. The comfort could be better.”
"On the one hand, it is for personal use, and we 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."
This kind of use The idea of twin turbofans replacing four turboprops was relatively rare in 2000.
But after 2010, it will basically become the preferred object of all countries in the world.
For example, the KC390 developed by Embraer has almost become the first choice among aircraft of the same level in the 2020s.
The Netherlands, Hungary, Portugal, South Korea, and even the U.S. Air Force are all in favor of this model.
Although Huaxia's products are unlikely to be sold in the United States, other markets can still compete.
After all, even Rafale’s engines use Chinese technology.
After all, the sensitivity of transport aircraft is much lower than that of main battle equipment...
